Title of talk: The Perils of Pre-Smoothing Light Curves Prior to Conducting Transit Searches
Abstract
The transit method is the most successful technique for identifying exoplanet, producing ~75% of the ~6000 known exoplanets to date. Detection theory provides tools for dealing with non-white (Gaussian) stochastic noise processes often encountered in astronomical contexts, including the detection of weak transiting planet signatures in time series photometric observations of star fields. In this talk I present an overview of the application of detection theory to the search for transiting planets and describe its implementation for the Kepler and TESS science pipelines developed at NASA Ames Research Center. I also discuss how common approaches to transit detection that include pre-smoothing the photometric time series prior to applying a simple matched filter, such as Box Least Squares and Transit Least Squares, are inherently suboptimal and can lead to invalid and/or misleading results.

Titleof talk:ThefirstAGIwillbeFederated
Abstract
As established scaling laws indicate, the future performance improvements of AI depend on the amount of computing and data sources we can leverage. Where will we get the necessary compute and data to drive the continued advances in AI that the world now has grown to expect? I believe all roads lead to federated learning, and approaches of this kind. In the relatively near future, decentralized and federated techniques in machine learning will be how the strongest LLMs (and foundation models more generally) are trained; and in time, aspirational capabilities like AGI will finally be achieved, in part, due to the adoption of federated methodologies. In this talk, I will describe why the future of AI will be federated, and describe early solutions developed by Flower Labs and CaMLSys that address the underlying technical challenges that the world will face as we shift from a centralized data-center mindset to de-centralized alternatives.

Title of talk: Future Societies Are Driven by Sustainability and Resilience Besides 6G Enabled Efficiency Improvements
Abstract
The usage scenarios of IMT-2030 will expand on those of IMT-2020. In addition, IMT-2030 will enable new use cases arising from 6G capabilities, such as AI and sensing, which previous generations of IMT were not designed to support. The grand targets for IMT-2030 include supporting sustainable development, enabling ubiquitous intelligence, connecting the unconnected, and maintaining security and resilience. 6G Metaverse-type applications are pushing researchers to explore the limits of realizable communication systems, while real-time automation with high reliability drives system optimization in another direction. The challenges are enormous, requiring the provision of sufficient and trustworthy coverage and services regardless of user location. What do these developments mean for technology enablers? How should spectrum regulation evolve to meet future needs? What changes are necessary in value chains and ecosystems? How should future networks be developed to enable truly ubiquitous digital services? How can we improve the resilience of mobile networks? These are some of the questions we must critically discuss before rushing into the tedious 3GPP standards process.

Title of talk: Vision Transformer Quantization for Efficient Deep Learning
Abstract
Vision transformers (ViTs) have demonstrated state-of-the-art performance across various computer vision tasks. However, the deployment of ViT models on edge platforms is limited by their high computational cost and large memory footprint. Quantization of vision transformers reduces memory usage and computational load by representing network parameters with lower precision. In this talk, we discuss vision transformer quantization strategies, including knowledge distillation, post training quantization and quantization aware training. We present a new explainability-based approach for mixed-precision quantization of vision transformers that is designed to provide efficiency and maintain performance. Our results demonstrate the effectiveness of mixed-precision models compared to fixed bit quantization.

Title of talk: A framework for soft decision code construction
Abstract
In a hard detection setting, the minimum Hamming distance and, more generally, the Hamming weight spectrum of a binary linear error correction code form key indicators of its quality. In the presence of soft information, where each received bit has an associated likelihood of being correct, Hamming statistics are usually regarded as being appropriate proxies for code quality as it is not evident how to incorporate the impact of the continuous side information into considerations.
Inspired by the operation of Ordered Reliability Bits Guessing Random Additive Noise, which has recently been proven to be almost capacity achieving, we introduce a simple new model of the soft detection setting called the Linear Reliability Channel. Despite capturing all core facets of soft information decoding, it is a discrete model where soft detection channel reliabilities are described by the declaration of a random permutation of received bits. This channel model provides a discrete framework for assessing soft detection performance through combinatoric considerations, including the determination of appropriate statistical correlates to high quality soft detection codes.

Title of talk: FAQ: A Fuzzy-Logic-Assisted Q Learning Model for Resource Allocation in 6G V2X
Abstract
Cellular V2X (CV2X) communications empower advanced applications but at the same time bring unprecedented challenges in how to fully utilize the limited physical-layer resources, given the fact that most of the applications require both ultra-low latency, high data rate and high reliability. Resource allocation plays a pivotal role to satisfy such requirements as well as guaranteed quality of service (QoS). In this Talk, we introduced our proposed novel fuzzy logic assisted Q learning model (FAQ) is proposed to intelligently and dynamically allocate resources by taking advantage of the centralized allocation mode. The proposed FAQ model reuses the resources to maximize the network throughput while minimizing the interference caused by concurrent transmissions. The fuzzy-logic module expedites the learning and improves the performance of the Q-learning.

Title of talk: Extreme precipitation nowcasting using deep generative models
Abstract
Extreme weather events, such as the floods recently in Valencia, Spain, have led to substantial impacts, including loss of life and major economic losses. Therefore, weather forecasts need to become more reliable, especially for extreme weather events. There has been a recent breakthrough in precipitation nowcasting, which is precipitation forecasting for the next few hours: Machine learning models, particularly deep generative models, can provide improved forecast quality compared to the state-of-the-art nowcasting and physics-based models. However, these new models are not adequate for extreme weather events. In our team, we are developing new deep generative models specifically for nowcasting extreme precipitation. Concretely, we are designing transformer-based generative models, in particular, VideoGPT with Extreme Value Loss (EVL) regularization. Leveraging a comprehensive dataset from the Royal Netherlands Meteorological Institute (KNMI), we aim to predict short-term extreme precipitation with high accuracy. We introduce a novel method for computing EVL without assuming fixed extreme representations, addressing the limitations of current models in capturing extreme weather events. Currently, we are also validating our deep generative nowcasting models on datasets from the US, Singapore, and India. We will present both qualitative and quantitative analyses, demonstrating the superior performance of the proposed VideoGPT-EVL in generating accurate precipitation forecasts, especially when dealing with extreme precipitation events.

Title of talk: Affective Computing for Alzheimer's: Unlocking the Power of Visual Data
Abstract
Alzheimer's Disease (AD) presents a significant global health challenge, characterized by progressive cognitive decline and emotional disturbances. Traditional diagnostic methods often rely on subjective assessments and can be time-consuming. In recent years, advancements in artificial intelligence and computer vision have opened new avenues for early detection and improved management of AD.
A key area of exploration lies in leveraging image analysis for affective computing. By analyzing visual data such as facial expressions, body language, and gait patterns, intelligent systems can objectively assess emotional states, cognitive function, and behavioral changes in individuals with AD. This approach offers the potential to identify subtle signs of cognitive decline, such as apathy, anxiety, and depression, which may precede overt symptoms and provide valuable insights into disease progression.
An exploration of image analysis applications in affective computing forms the foundation of this talk. The review begins by examining how affective computing intersects with image analysis techniques. Building upon these fundamentals, we delve into various methods of emotion recognition through visual data, encompassing facial information. The discussion concludes by investigating the potential impact and current limitations of these technologies in studying neurodegenerative conditions.

Title of talk: Physical Layer Security in Cell-Free Massive MIMO
Abstract
Cell-free massive multiple-input multiple-output (MIMO) is a system where many (hundreds or thousands) access points or base stations coherently serve many (tens or hundreds) users. Unlike current cellular (mobile) networks where the coverage area is divided into cells, in cell-free massive MIMO, there are no fixed cells or cell boundaries. Cell-free massive MIMO is expected to overcome the boundary effect—the inherent limitation of current cellular networks which has persisted for the last 50 years. It is expected to ensure connectivity everywhere, fulfilling the key requirements of next-generation wireless communication systems (beyond 5G and towards 6G). In this talk, we will first focus on the fundamentals of cell-free massive MIMO. We will then discuss the PHY security aspects of cell-free massive MIMO, along with a range of important topics and future directions.

Title of talk: Autonomous Spectrum Awareness for Spectrum Innovation in Future Networks
Abstract
While mmWave and THz spectrum bands have been proposed to provide the high data rates required by several key 6G applications, lower (sub-6 GHz) spectrum bands remain critically important to the success of 6G. In this context, spectrum sharing is seen as the way forward to fully exploit the potentials of all available spectrum bands. However, harmonious spectrum sharing requires accurate spectrum awareness information for the interference-free coexistence of various networks in the same spectrum. Databases have been the preferred choice (e.g., WRAN, LSA, CBRS), with direct spectrum monitoring (sensing) seen as a secondary or complementary requirement. This talk explores the possibility of a fully autonomous spectrum awareness system entirely based on independent spectrum monitoring, which removes the need of external network infrastructure and external database providers and enables fully autonomous operation of dynamic spectrum sharing systems. The talk presents the underlying idea of such system concept as well as different approaches to overcome practical limitations (including heuristic algorithms, analytical-based solutions and deep-learning techniques). The performance of these approaches is compared and a proof-of-concept validation based on software defined radios is presented as well. A practical application example in the coexistence between cellular and wireless LANs is described as well.

Title of talk: Reducing Label Dependency for Automated Analysis of Underwater Imagery
Abstract
With the increasing use of robotics to study coral reefs and seagrass meadows, vast amounts of imagery are generated. Traditionally, analyzing this data has been challenging, time-consuming, and expensive, as it heavily relied on marine experts. This talk describes innovative artificial intelligence methods which automatically identify marine species and reduce the annotation effort for domain experts. These contributions span design of data collection and annotation methodology; segmentation from image-level labels only; and use of large language models as a supervisory signal in domain-specific applications. The talk will also describe a human-in-the- loop labelling regime where a model and marine scientist work together to improve annotation efficiency for coral images. Finally, I will describe our work with the Reef Restoration and Adaptation Program and the Australian Institute of Marine Science on the Deployment Guidance System, which performs broad-scale automated distribution of coral re-seeding devices.

Title of talk: Tactile Intelligence and Haptics: Paving the Way for Breakthroughs in Robotics and Advanced Prosthetics
Abstract
Despite significant advancements in the field of robotics, robots remain largely confined to warehouses and industrial settings, yet to seamlessly integrate into our daily lives or operate effectively in unstructured environments. One key limitation is the absence of robust tactile sensing—a fundamental sense that enables humans to navigate safely, manipulate objects with dexterity, and adapt to unpredictable surroundings. Unlike localized senses such as vision or hearing, tactile sensing relies on a vast network of mechanoreceptors with varying densities, distributed across complex 3D surfaces. To replicate this in robots, tactile sensing systems must also be flexible, scalable, and capable of covering large, irregular areas—posing significant challenges compared to artificial vision or auditory processing. In the realm of prosthetics, tactile sensing plays an equally crucial role in fostering embodiment—the feeling that a prosthetic limb is a natural extension of the body. Without rich sensory feedback, users struggle with precise control and intuitive interaction with their environment. Integrating electronic skin (e-skin) with advanced haptic feedback mechanisms can bridge this gap, enhancing both functionality and the psychological acceptance of prosthetic limbs.
This talk will explore my research on developing tactile sensing electronic skin (e-skin) for robotics and prosthetics, addressing critical aspects such as material innovations, device architectures, fabrication techniques, system interfaces, intelligence and applications. Advancing tactile intelligence holds transformative potential, paving the way for more adaptive, human-like robots, next-generation prosthetics and rehabilitation technologies.

Title of talk: AI Ethics in Education: Confronting the Rise of “Erudite Illiterates”
Abstract
As artificial intelligence continues transforming the educational landscape, the rise of AI-generated content (AIGen) presents extraordinary opportunities and profound ethical dilemmas for higher education. In this keynote, we will explore the pivotal question: how can educators and institutions embrace AIGen as a tool for innovation while safeguarding academic integrity, equity, and the essence of learning? This session dives deep into the transformative potential of AIGen to personalize learning, streamline administrative tasks, and foster creativity in teaching and research. At the same time, we’ll confront the challenges of plagiarism, bias, and the risk of diminishing critical thinking skills in a world where AI can compose essays, solve equations, and even generate lesson plans. More importantly, this talk calls for a shared commitment to an ethical framework for AIGen adoption that champions transparency, equity, and the enduring value of human intellect. By addressing these challenges head-on, we’ll empower educators, administrators, and students to become co-creators of an AI-enhanced future where technology enriches, rather than undermines, the pursuit of knowledge.

Title Improving Estimates of the Frequency of Earth-like Planets in the Habitable Zone of Sun-Like Stars by Reprocessing the Kepler Dataset
Abstract :
NASA is moving forward with the Habitable Worlds Observer (HWO) mission concept recommended by the 2020 Astrophysics Decadal Survey and slated for launch in the 2040s. HWO is expected to be a 6-m class IR/Op-cal/UV Observatory optimized for exoplanets and general astrophysics and one of the most powerful space-born observatories ever conceived. Its chief goal is to image ~25 planetary systems around Sun-like stars, including Earth-size exoplanets in their star’s habitable zone and characterize their atmospheric content. By measuring the spectra of these planets, HWO will search for biosignatures such as water, methane, oxygen and/or ozone. The success of HWO depends on η⊕, the expected number of Earth-size exoplanets orbiting in the habitable zone of a Sun-like star. This defines the distance out to which HWO needs to operate to achieve its goals, and thus its size and performance, which are the primary cost drivers. Current estimates of η⊕ have very large uncertainties, primarily due to the paucity of reliable Earth-size, rocky exoplanets in the habitable zone of Sunlike stars. The Kepler mission dataset will likely be the only high-quality data set available in time to inform HWO’s design. Since the end of the Kepler mission, a great deal has been learned about transit detection, the construction of exoplanet catalogs suitable for population studies, and the inference of η⊕ from such catalogs. Kepler data are better understood, and better approaches to photometry and systematic error correction have been developed. Most significantly, the Gaia mission has delivered vastly improved, high-precision stellar catalogs to better understand the stellar population observed by Kepler as well as the background stars around each target. Gaia will help to improve the quality and precision of Kepler data products and the sensitivity of the planet search, enabling the detection of more small exoplanets in the habitable zone of Sun-like stars. Our team was awarded a 5-year grant to develop an improved version of the Kepler pipeline and to reprocess all Kepler data, starting from the existing calibrated pixels and ending with a new exoplanet catalog and η⊕ computation. Our pipeline will be open source, written in java and python, leveraging existing software whenever possible,and designed for wide use with general transit data. We hope to encourage community efforts to explore complementary techniques and technologies to this effort by developing the code in the open to achieve the best estimates for η⊕ and thus, the best design requirements for HWO.

Title Blockchain Tokens for Universal Encrypted Access: A System for Healthcare Information Networks
Abstract :
The digitization of healthcare, driven by technological advancements and the digitization of medical records, presents both opportunities and challenges in secure and efficient medical data management. Key concerns revolve around data security, privacy, and accessibility, particularly in the centralized nature of existing systems. Blockchain technology has emerged as a promising solution, offering a decentralized and transparent framework for data exchange and management. However, the interoperability of multiple blockchain-based healthcare networks presents a new challenge, limiting their effective utilization in the healthcare sector. Inadequate data management across different blockchain systems can lead to duplications, inconsistencies, and inefficiencies, putting patient record privacy and security at risk. To tackle these challenges, this thesis proposes a novel approach by introducing blockchain tokens as a universal encrypted access system, facilitating the seamless transfer of patients' medical data across various blockchain-based healthcare networks. Assigning a unique token to each patient addresses the issues of data fragmentation and lack of interoperability that impede blockchain adoption in healthcare. To achieve universal access using tokens, our solution leverages distributed storage systems (DSS), employs steganography and integrates cryptographic techniques. DSS eliminates centralized storage of sensitive medical data, preventing a single point of failure. To protect against the public nature of DSS and the NFT metadata, steganography protects data unique identifiers and sensitive metadata, granting access only to authorized parties. Information is further secured with a strong password when embedded within an image, serving as an NFT image for simplified data retrieval during patient transitions. Cryptographic techniques secure password transfer during patient mobility across networks. Our model leverages the mutability of NFT data to introduce "updatable patient-specific NFTs" for accommodating dynamic medical data while using the immutability of NFT data to establish an ownership mechanism for patients that ensures privacy, uniqueness, and a trusted sharable protocol. This approach seamlessly integrates new patient records in real time on the public blockchain. To evaluate the feasibility, a scoping study is conducted using a medical test network to explore Hyperledger blockchain capabilities in healthcare records management (HRM). Building on insights gained, the scope expanded to two blockchain medical networks, engaging multiple institutions in implementing and testing the integration of medical records on IPFS within the private blockchain network via updatable NFTs on a public blockchain. Performance analysis confirms feasibility and effectiveness and validates practical application potential.

Title Virtually Full-Duplex Cell-Free Massive MIMO for 6G
Abstract :
Cell-free massive multiple-input multiple-output (MIMO) is a system where many (hundreds or thousands) access points or base stations coherently serve many (tens or hundreds) users. Different from the current cellular (mobile) networks where the coverage area is divided into cells, in cell-free massive MIMO, there are no cells or cell boundaries. Cell-free massive MIMO is expected to overcome the boundary effect--the inherent limitation of the current cellular networks which persists over the last 50 years. It is expected to ensure everything and everywhere get connected, and hence, fulfils the key requirements of next generation wireless communication systems (beyond 5G and towards 6G). In this talk, we will first focus on the fundamentals as well as signal processing designs for virtually full-duplex cell-free massive MIMO where full-duplex transmission is virtually realized via half-duplex hardware devices. A range of important topics and future directions will be then discussed.

Title Machine Learning and the Data Center: A Dangerous Dead End
Abstract :
The vast majority of machine learning (ML) occurs today in a data center. But there is a very real possibility that in the (near?) future, we will view this situation similarly to how we now view lead paint, fossil fuels and asbestos: a technological means to an end, that was used for a time because, at that stage, we did not have viable alternatives – and we did not fully appreciate the negative externalities that were being caused. Awareness of the unwanted side effects of the current ML data center centric paradigm is building. It couples to ML an alarming carbon footprint, a reliance on biased close-world datasets, serious risks to user privacy – and promotes centralized control by large organizations due to the assumed extreme compute resources. In this talk, I will offer a sketch of preliminary thoughts regarding how a data center free future for ML might come about, and also describe how some of our recent research results and system solutions (including the Flower framework -- http://flower.dev) might offer a foundation along this path.

Title Vacuum processed Perovskites for Optoelectronic Devices
Abstract :
Metal-halide perovskites made a breakthrough in photovoltaic and light-emitting technologies in the last ten years. MHPs are one of the most promising low-cost materials, due to their excellent optoelectronic properties and fabrication versatility. Since the advent of the first perovskite solar cells (PSCs) in 2009, their power conversion efficiency (PCE) has now reached 25.6% [1], for active areas smaller than 1 cm2 and their operational stability is constantly improving [2-4]. The interest in transferring the existing technology into large-area perovskite modules using industrial-compatible techniques is exploding. In this talk, I will show why thermal evaporation is a promising perovskite fabrication technique to bring this technology closer to reliable and extended production, by relying on excellent size scalability, promising stability, fine composition control, and surface adaptability [5]. The co-evaporated perovskite thin ?lms are uniform over large areas with low surface roughness and a long carrier lifetime. I will present our highly ef?cient, large area, PSCs where the MAPbI3 perovskite is deposited by thermal co-evaporation. Developing optimization strategies customized for n.i.p [6, 7] and p.i.n [8] architectures the PSCs achieved PCEs above 20% in both configurations. Moreover, the co-evaporated MAPbI3is formed intrinsically strain-free and the PSCs showed remarkable structural robustness and impressive thermal maintaining over ≈80% of their initial PCE after 3600 under continuous thermal aging at 85 °C without encapsulation [9].

Title Dimensions of Assessing the Quality of Peer Review Reports of Scientific Articles
Abstract :
Assuring the quality control of publications in the scientific literature is one of the main challenges of the peer review process. Consequently, there has been an increasing demand for computing solutions that will help to maintain the quality of this process. Recently, the use of Artificial Intelligence techniques has been highlighted, applied in the detection of plagiarism, bias, among other functions. The assessment of the reviewer’s review has also been considered as important in the process, but little is known about it, for instance, which techniques have been applied in this assessment or which criteria have been assessed. Therefore, a systematic literature review was made to find evidence regarding the computational approaches that have been used to evaluate reviewers' reports. To achieve this, five online databases were selected, from which 72 articles were identified that met the inclusion criteria of this review, all of which have been published since 2000. The result returned 10 relevant studies meeting the evaluation requirements of scientific article reviews. The review revealed that mechanisms to rank review reports according to a score, as well as the word analysis, are the most common tools, and that there is no consensus on quality criteria. The systematic literature review has shown that reviewers’ report assessment is a valid tool for maintaining quality throughout the process. However, it still needs to be further developed if it is to be used as a resource which surpasses a single conference or journal, making the peer review process more rigorous and less based on random choice.

Title Gaussian Process Methods for Object Detection, Tracking and Sensor Scheduling with Uncertainty Qualification
Abstract :
Sensor networks generate massive amounts of data. These are often comprised of sensors with different modalities such as radar, acoustic sensors, LIDAR, combined with optical and thermal cameras. Moreover, data arrives with different time rates and levels of accuracy. Making sense of such multiple heterogeneous data is a challenging task that has been extensively studied, but the provision of reliable solutions for autonomous and semi-autonomous systems is a task that remains only partially solved. Fusion of data from multiple heterogeneous sensors of this type is part of the challenge; even more so when the autonomous decisions have to be performed in sequentially and in real-time. Capturing confidence and uncertainty from the integration of heterogeneous large-scale data remains a challenging task.
This talk will present recently developed Gaussian process methods for object detection, tracking and sensor scheduling. Both centralised and decentralised methods will be presented. The power of the methods is especially when dealing with different uncertainties in the sensor data and quantifying their impact on the developed solutions. These can be part of safe and reliable autonomy at different levels.

Title Fuzzy based Fall Risk Prediction in Older Adult’s.
Abstract :
The global elderly population is increasing rapidly, leading to a rise in chronic illnesses and co-existing conditions, which in turn results in higher healthcare expenses. Accidental falls are among the leading causes of injury-related deaths in elderly individuals. This study aims to create a real-time monitoring system using vital signs to foresee a future fall in older adults by identifying abnormalities through continuous monitoring. The proposed fall prediction technique, employing the Fuzzy-based Fall Prediction Algorithm, utilizes Fuzzy rules to learn and execute tasks. The obtained results are then classified according to different levels of predicted risk indicators. The developed model is tested using data from older adults sourced from a public repository and compared with the results of the theoretical evaluation. The simulated outcomes demonstrate that the proposed algorithm achieves 96% accuracy, 93.75% sensitivity, and 100% specificity. Utilizing these advancements in the proposed heterogeneous technology allows for the early prediction of falls in the elderly and can potentially save lives.

Title Advancements in Visual Place Recognition: From Loop Closure to Localization and Beyond
Abstract :
In this presentation, I will explore the evolving landscape of Visual Place Recognition (VPR), a critical component in robotics that allows machines to recognize previously visited locations based solely on visual data. While early applications were largely confined to loop closure in Simultaneous Localization and Mapping (SLAM), the utility of VPR is now being extended to localization-only pipelines where a pre-existing map is available.
Key Highlights include:
- Event-Based Sensing and Processing: I will focus on innovative methods utilizing event cameras and spiking neural networks for enhanced VPR capabilities.
- State-of-the-Art Methods: An introduction to ground-breaking techniques that are redefining VPR, including our award-winning method, Patch-NetVLAD.
- RoboStack: RoboStack is a versatile tool for running the Robot Operating System (ROS) across multiple operating systems while integrating the latest packages in machine learning, computer vision, and robotics.

Title Continual Adaptation in Gradually Changing Environments
Abstract :
As deep learning models get deployed in the real world, they encounter a new set of challenges including robustness, generalization and adaptation. The performance of classification models degrades significantly when operating in new environments with different distributions compared to the training data. Domain Adaptation (DA) aims to overcome the dataset bias problem by closing the gap in classification performance between the source domain used for training and the target domain where testing takes place. We present a new framework for Continual Domain Adaptation, where the target domain samples are acquired in small batches over time and adaptation takes place continually in gradually changing environments. Our Continual Domain Adaptation approach utilizes concepts from both DA and continual learning and achieves state-of-the-art results on various datasets under challenging conditions.

Title Perception error modelling for autonomous driving
Abstract :
Even though virtual testing of Autonomous Vehicles (AVs) has been well recognized as essential for safety assessment, AV simulators are still undergoing active development. One particular challenge is the problem of including the Sensing and Perception (S&P) subsystem into the virtual simulation loop in an efficient and effective manner. In this article, we define Perception Error Models (PEM), a virtual simulation component that can enable the analysis of the impact of perception errors on AV safety, without the need to model the sensors themselves. In this talk, we propose a generalized data-driven procedure towards parametric modeling , and we demonstrate the usefulness of PEM-based virtual tests, by evaluating camera, LiDAR, and camera-LiDAR setups. Our virtual tests highlight limitations in the current evaluation metrics, and the proposed approach can help study the impact of perception errors on AV safety.

Title Brain over Brawn: Rethinking Robot Learning for Autonomy at Scale
Abstract :
A long-standing vision has been to create intelligent robots capable of learning from the world around them to assist humans in everyday tasks from domestic chores to transportation. However, most robots deployed today are still tailored for specific tasks and environments, avoiding contact with humans. Although the past decade has witnessed unprecedented advances in machine learning techniques for various autonomy tasks, they have increased the dependency on manually annotated labels or reward engineering, which are both environment- and task-specific. Moreover, as different robots have different hardware configurations (e.g., sensor modalities, viewpoints, locomotion), the transferability of these learned autonomy modules has become even more challenging. To achieve our goal of ubiquitous robots, we need to develop learning methods for robot autonomy that generalize effectively across diverse tasks, robots, and unstructured environments. In this talk, I will present our efforts in alleviating the aforementioned challenges in service robots ranging from autonomous vehicles to mobile manipulators. Specifically, I will discuss three fundamental aspects of learning autonomy at scale: 1) learning multiple diverse tasks simultaneously by sharing knowledge and exploiting complementary cues, 2) learning to adapt tasks across different robots and environments, and 3) learning efficiently with minimal human supervision. These techniques have not only facilitated setting the new state-of-the-art, they have opened doors to a wide variety of new applications in human-centered environments. Lastly, I will conclude the talk by presenting our ongoing efforts to address fairness in robot learning for ensuring safe, trustworthy, and responsible innovation, which is crucial for both scalability and fostering acceptance in society.

Title Antenna arrays of sub-wavelength size for beamforming and localization within limited volume
Abstract :
Traditionally, the beamforming and angle of arrival estimation are performed with large antenna arrays, where antennas are separated by l/2 distance. However, this approach does not allow for antenna miniaturisation, as larger aperture size is required for better angular resolution. In this talk, a new approach is proposed, which relies on direct spherical-mode beamforming; It generates a number of omnidirectional spherical modes, with each mode exhibiting an intrinsic phase-variation across its radiation pattern. Since each mode is by definition orthogonal, it can be independently controlled. Therefore, by applying appropriate phase shift, an unidirectional beam can be created. Overall, the proposed antennas have total diameter between 0.6 – 0.76 l wavelength, which respectively offer size reduction of 70 – 60% as compared to linear arrays, with Angle-of-arrival resolution outperforming their larger counterparts.

Title Achieving Extreme Link Reliability for xURLLC Services in 6G Networks
Abstract :
There is an urgent need to support extremely ultra-reliable connectivity in 5G/6G emerging applications such as Industry 5.0, intelligent transportation systems, tactile Internet, remote healthcare, mission-critical services and ad-hoc disaster/emergency relief, among others. The demanding requirements set in terms of connection reliability for such applications make the wireless access design very challenging in terms of protocols and associated transmission techniques. In this context, this talk will provide a brief overview of the 5G/6G use cases, with a special emphasis on extreme Ultra-Reliable Low-Latency Communication (xURLLC), and will introduce a novel technique specifically devised to improve the link reliability for 5G/6G services based on an hybrid transmission scheme with adaptive diversity combining that dynamically switches between sub-6GHz/mmWave/THz bands to exploit their complementary characteristics. This novel scheme can achieve the same level of reliability as a continuous dual-link transmission scheme but with a much lower level of link usage and without sacrificing (and indeed enhancing) the capacity, thus making it a suitable candidate to deliver xURLLC services in a resource-efficient manner.

Title Universal decoding - revisiting the need for standardization in error-correcting codes
Abstract :
While 5G has provided some notable successes in introducing new technologies, such as millimeter wave and adoption of massive multi-input multi-output (MIMO), many of the above desiderata have been pushed at this stage to 6G. The causes of these unrealized ambitions are varied, but much can be attributed to the fact that the architecture of 5G remains patterned after previous generations, an overlay of many quasi-sedimentary layers of successive legacies, from conventional suboptimal modulations, to interleaving over channels, to being limited to a small number of long-and low-rate physical layer codes such as LDPCs, to hybrid ARQ and ARQ repetition at the MAC and transport layers. 5G has often resorted to increasing bandwidth to mask the inefficiencies of these legacy issues by running systems in fast forward.

Title A Joint Physical-Layer Network Coding Based Medium Access Control
Abstract :
Vehicular network plays a crucial role in intelligent transportation system. It can provide road safety by broadcasting Basic safety message (BSM). Based on the framework of Dedicated Short-Range Communication (DSRC), this paper proposes an efficient and reliable MAC protocol for BSM packets dissemination in last-mile vehicular networks from the train station. It perfectly integrates Physical-Layer Network Coding (PNC) and Random Linear Network Coding (RLNC) in both roadside unit (RSU) and onboard unit (OBU) nodes. Comprehensive simulation shows that compared with the existing schemes for BSM dissemination, the proposed protocol achieves both high flexibility and excellent performance in packet delivery ratio (PDR).

Title Ziggy, a Portable, Scalable Infrastructure for Science Data Processing Pipelines and its Application to a Proxy, Legacy Global Hyperspectral Data Set for NASA’s Earth System Observatory’s Upcoming Surface, Biology and Geology Mission
Abstract :
The Surface Biology and Geology (SBG) mission recently passed mission confirmation review and has entered phase A – design and development. SBG will acquire high resolution solar-reflected spectroscopy and thermal infrared observations at a data rate of ~2.5 TB/day and generate products at ~40 TB/day. Given that the per-day volume is greater than NASA’s total extant airborne hyperspectral data collection, collecting, processing, disseminating, and exploiting the SBG data present new challenges. To meet these challenges, we have developed a prototype science data processing pipeline using a legacy hyperspectral data set to help prepare for SBG’s flight. Our science pipeline infrastructure, Ziggy, is based on the technology developed for NASA’s Kepler and TESS planet-hunting missions. We integrated Ziggy with Earth Observer-1/Hyperion workflows to build a prototype SBG pipeline and ingested the 17-year Hyperion archive that provides globally sampled visible through shortwave infrared spectra that are representative of SBG data types and volumes. We fully implemented the first stage and processed the entire 55 TB Hyperion data set from the raw data (Level 0) to top-of-the-atmosphere radiance (Level 1R). We are currently evaluating the ISOFIT atmospheric correction module to convert the L1R data to surface reflectance spectra (Level 2) before reprocessing the full data set to L2. Cross Checks are being performed with RadCalNet as well as with coincident observations by AVIRIS. This effort demonstrates that Ziggy can significantly reduce the cost, risk and time required to develop complex science data processing pipelines for extremely large data sets.

Title Identifying psychiatric manifestations in schizophrenia and depression from audio-visual behavioral indicators through a machine-learning approach
Abstract :
Schizophrenia (SCZ) and depression (MDD) are two chronic mental disorders that seriously affect the quality of life of millions of people worldwide. We aim to develop machine-learning methods with objective linguistic, speech, facial, and motor behavioral cues to reliably predict the severity of psychopathology or cognitive function, and distinguish diagnosis groups. We collected and analyzed the speech, facial expressions, and body movement recordings of 228 participants (103 SCZ, 50 MDD, and 75 healthy controls) from two separate studies. We created an ensemble machine-learning pipeline and achieved a balanced accuracy of 75.3% for classifying the total score of negative symptoms, 75.6% for the composite score of cognitive deficits, and 73.6% for the total score of general psychiatric symptoms in the mixed sample containing all three diagnostic groups. The proposed system is also able to differentiate between MDD and SCZ with a balanced accuracy of 84.7% and differentiate patients with SCZ or MDD from healthy controls with a balanced accuracy of 82.3%. These results suggest that machine-learning models leveraging audio-visual characteristics can help diagnose, assess, and monitor patients with schizophrenia and depression.

Title Can we keep humans away from sewers?
Abstract :
Safe, efficient and cost effective condition assessment of all shapes of wastewater assets is significant for the wastewater managers. The value of sewerage infrastructure assets in the United States and Australia is estimated to be more than $1 trillion and $100 billion respectively. Wastewater assets are deteriorating at a cost estimated to be $13.75 billion per year in the United States, $50 billion per year in Germany, and $100 million per year in Australia, which are further expected to rise. Failure to maintain such infrastructures will result in a variety of negative economic, social and environmental consequences for utilities and the governments. With increasing urbanization, industrialization, effects of climate change and expectation of higher quality of life and reputation, there is an unprecedented demand for making the old wastewater systems more efficient, durable and resilient. This requires frequent, safe, cost effective and efficient condition assessments without exposing humans in sewers.

Title Analysing the affective computing by image processing
Abstract :
The physiological signals also known biosignals, most common and used for biomedical and biometric identification, are the electrocardiogram (ECG) and electroencephalogram (EEG). ECG measures the electrical activity of the heart and EEG measures the electrical activity of the brain. There is other very rarely used signals that we consider studying as part of this work. For example, the electromyogram (EMG) which is a record of the electrical activity produced by the muscles and nerves and the galvanic skin response (GSR)or skin conductance, which is an indication of psychological or physiological arousal such as fear, anger or other feelings. The detection of the degree of emotion through physiological signals is a very poorly studied area that can offer a new and efficient system, which deals with using the combination of several physiological signals as a method of identifying the degree of emotion in affective computing. The objective of this proposal is to analyze the physiological signals that show people's emotions, quantify it and perform an automatic detection, which can become an innovative and robust tool that shows the degree of emotion

Title Chiral spintronics for massive digital data memory-storage
Abstract :
Spintronics is a field of research that harnesses the electron’s spin to create novel materials with exotic properties and devices especially those for storing digital data that is the lifeblood of many of the most valuable companies today. Spintronics has already had two major technological successes with the invention and application of spin-valve magnetic field sensors that allowed for more than a thousand-fold increase in the storage capacity of magnetic disk drives that store ~70% of all digital data today. Just recently, after almost a 25-year exploration and development period, a high performance nonvolatile Magnetic Random Access Memory, that uses magnetic tunnel junction memory elements, became commercially available. A novel spintronics memory-storage technology, Magnetic Racetrack Memory is on track to become the third major success of spintronics. Racetrack Memory is a novel, non-volatile memory in which data is encoded in mobile chiral domain walls that are moved at high speeds by current induced spin-orbit torques to and thro along synthetic antiferromagnetic racetracks. Chiral domain walls are just one member of an ever-expanding family of nano-scopic chiral spin textures that are of great interest from both a fundamental as well as a technological perspective. A zoology of complex spin textures have been discovered including, anti-skyrmions, elliptical Bloch skyrmions, two-dimensional Néel skyrmions, and fractional anti-skyrmions. Finally, I will discuss some of our recent work in superconducting spintronics that could lead to a very low energy-consuming cryogenic racetrack memory that is needed for advanced quantum computing systems.

Title Algebras for Advanced Signal Processing and Data Mining: New Analytical Tools Beyond Calculus
Abstract :
Linear algebra, multivariate calculus, applied probability and statistics, and convex optimizations are well-established mathematical tools that have been used extensively in designing variety of engineering systems. These tools are very effective in processing numerical values as well as manipulating basic mathematical objects including variables, vectors and functions. However, as the systems are getting much more sophisticated and embed intelligent decision makings, their design demands much more advanced approaches and going beyond traditional calculus. There is a great need to work with more advanced mathematical structures and abstractions. This talk will outline modern algebraic concepts for abstract modeling and manipulating complex mathematical structures including data topology, algebras and category theory.

Abstract :
In this talk, mathematical formulations of five design specifications in accordance with the three-dimensional drawing with programming implementations by MATLAB are presented. For designing controllers by using the introduced three-dimensional graphical method, system design specifications such as phase margin, gain margin, phase flatness, low-frequency output disturbance rejection and high-frequency noise rejection are considered, and their important characteristics are shown. The requirements are mapped in the three-dimensional Euclid space by three-dimensional surfaces or lines so that the proportional, integral, derivative control coefficients can be chosen to meet the given specifications in an optimum way and to allow trade-off or compromise.

Title The Road to 6G: From MIMO to Cell-Free Massive MIMO
Abstract :
Cell-free massive multiple-input multiple-output (MIMO) is a system where many (hundreds or thousands) access points or base stations coherently serve many (tens or hundreds) users. Different from the current cellular (mobile) networks where the coverage area is divided into cells, in cell-free massive MIMO, there are no cells or cell boundaries. Cell-free massive MIMO is expected to overcome the boundary effect--the inherent limitation of the current cellular networks which persists over the last 50 years. It is expected to ensure everything and everywhere get connected, and hence, fulfils the key requirements of next generation wireless communication systems (beyond 5G and towards 6G).

Title A Model for Information and Sensor Validation
Abstract :
Sensor validation is critical for many applications. Without it, machine learning and decision-making models suffer from the garbage in/garbage out problem. In this presentation, I will present a Bayesian model for information and sensor validation model that was developed with colleagues at Mexican Instituto de Electricas. The model represents relationships between variables using Bayesian networks and utilizes probabilistic propagation to estimate the expected values of variables. If the estimated value of a variable differs from the actual value, an apparent fault is detected. The fault is only apparent since it may be that the estimated value is itself based on faulty data. The theory extends our understanding of when it is possible to isolate real faults from potential faults and supports the development of an algorithm that is capable of isolating real faults without deferring the problem to the use of expert provided domain-specific rules. To enable practical adoption for real-time processes, an any time version of the algorithm is developed, that, unlike most other algorithms, is capable of returning improving assessments of the validity of the sensors as it accumulates more evidence with time. The developed model is tested by applying it to the validation of temperature sensors during the start-up phase of a gas turbine when conditions are not stable; a problem that is known to be challenging

Title Suppression of Gibbs Ringing in MR Images
Abstract :
Gibbs ringing arises when discontinuous signals are reconstructed from Fourier domain data. Such a situation occurs in magnetic resonance (MR) imaging, which measures discrete Fourier domain data. Ringing artifacts can confuse diagnosis based on such an MR image. There are a variety of algorithms for processing MR images to remove ringing artifacts, but these are poorly evidenced. We discuss the quantitative evaluation of such algorithms and present results.

Title Efficient CNNs and Transformers for Video Understanding and Image Synthesis
Abstract :
In this talk, I will first discuss approaches that reduce the GFLOPs during inference for 3D convolutional neural networks (CNN) and vision transformers. While state-of-the-art 3D CNNs and vision transformers achieve very good results on action recognition datasets, they are computationally very expensive and require many GFLOPs. While the GFLOPs of a 3D CNN or vision transformer can be decreased by reducing the temporal feature resolution or the number of tokens, there is no setting that is optimal for all input clips. I will therefore discuss two differentiable sampling approaches that can be plugged into any existing 3D CNN or vision transformer architecture. The sampling approaches adapt the computational resources to the input video such that as much resources as needed but not more than necessary are used to classify a video. The approaches substantially reduce the computational cost (GFLOPs) of state-of-the-art networks while preserving the accuracy. In the second part, I will discuss an approach that generates annotated training samples of very rare classes. It is based on a generative adversarial network (GAN) that jointly synthesizes images and the corresponding segmentation mask for each image. The generated data can then be used for one-shot video object segmentation

Title Multi-scale Representations for Human Pose Estimation
Abstract :
Human pose estimation is a topic of interest for research and applications, such as human-computer interaction, activity recognition and health monitoring. Pose estimation methods have advanced significantly due to deep learning architectures based on convolutional neural networks and more recently on vision transformers. We discuss an efficient Waterfall Atrous Spatial Pooling (WASP) architecture for multi-scale feature extraction that is useful for both pose estimation and semantic segmentation. Our waterfall architecture leverages the efficiency of progressive filtering in cascade, while maintaining multiscale fields-of-view comparable to spatial pyramid configurations. The waterfall module is used with various backbones in an encoder-decoder framework producing state-of-the-art results for single person and multi-person 2D pose estimation. We extend our framework to 3D pose from a single image and 2D hand pose estimation. We conclude by outlining new directions and applications for future work.

Title How Could we Increase Autonomy with Machine Learning Methods?
Abstract :
There is a fast development of different machine learning methods – for object classification, tracking, action recognition and other tasks with multiple types of data – from images and videos to time series data. Autonomous image and video analytics face a number of challenges due to the huge volumes of data that sensors provide, the changeable environmental conditions and other factors. However, it is important to know when the methods work well and when they are not reliable, e.g. how much could we trust the obtained results? How could we characterize trust is a related question. How could we quantify the impact of uncertainties on the developed solutions? This talk will discuss current trends in the area of machine learning and show results for image and video analytics for autonomous systems.

Title Co-Evaporated Metal Halide Perovskites: from Small Areas Solar Cells to Mini module
Abstract :
Metal-halide perovskites made a breakthrough in photovoltaic and light-emitting technologies in the last ten years. MHPs are one of the most promising low-cost materials, due to their excellent optoelectronic properties and fabrication versatility. Since the adventofthefirstperovskite solar cells (PSCs) in 2009, their power conversion efficiency (PCE) has now reached 25.6% [1], for active areas smaller than 1 cm2 and their operational stability is constantly improving [2-4]. The interest in transferring the existing technology into large-area perovskite modules using industrial-compatible techniques is exploding. In this talk, I will show why thermal evaporation is a promising perovskite fabrication technique to bring this technology closer to reliable and extended production, by relying on excellent size scalability, promising stability, fine composition control, and surface adaptability [5]. The co-evaporated perovskite thin ?lms are uniform over large areas with low surface roughness and a long carrier lifetime. I will present our highly ef?cient, large area, PSCs where the MAPbI3 perovskite is deposited by thermal co-evaporation. Developing optimization strategies customized for n.i.p [6, 7] and p.i.n [8] architectures the PSCs achieved PCEs above 20% in both configurations. Moreover, the co-evaporated MAPbI3is formed intrinsically strain-free and the PSCs showed remarkable structural robustness and impressive thermal maintaining over ≈80% of their initial PCE after 3600 under continuous thermal aging at 85 °C without encapsulation[9].

The approach has been through a striking evolution in the last years and it is becoming an increasingly important part of the healthcare infrastructure. So, telemedicine is usually present in Maturity Models for management of Hospital Information Systems, as a characteristic of maturity stages and/or maturity influencing factors. This talk starts with an introduction to growth stages theory and maturity models, specifically those related with information systems management. Then, an analysis and a discussion are done to show where telemedicine is positioned in Maturity Models for management of Hospital Information Systems and, at the end, some conclusions are drawn.

Title Deep Learning for Hematopathology
Abstract :
Computer Aided Diagnosis (CAD) systems are increasingly utilizing image analysis and Deep Learning (DL) techniques, due to their high accuracy in several medical imaging fields, including the detection of Acute Lymphoblastic (or Lymphocytic) Leukemia (ALL) from peripheral blood samples. CAD systems based on DL can support the pathologists in performing their decision by analyzing the blood samples images to determine the presence of lymphoblasts. However, when using DL, the limited dimensionality of ALL databases may highlight bias in the data and cause overfitting, favoring the use of transfer learning techniques to reduce the bias and increase the accuracy in the detection, in particular by considering Convolutional Neural Networks (CNN) pretrained on larger databases. This talk will present recent possible solutions for high accuracy ALL detection based on CNNs, addressing some of the problems of medical data, such as bias and limited dimensionality.

Title Innovative Antennas for Satellite Telecom, Radar Systems and Radio Telescope
Abstract :
The talk discusses the innovative antennas being developed for various telecom, radar and radio telescope applications. A 350 m diameter reflector antenna is being developed as a detector for the Lunar Crater Radio Telescope. Once deployed, it will be one of the largest filled aperture telescopes. The RF design and development thus involve complexities in terms of structural constraints and environmental interactions, which will be discussed in the talk. All metal circularly polarized patch excited cup antenna arrays being developed for direct to Earth communication from the potential Europa Lander and for Lunar missions. These antennas project the capability to survive high power levels, cryogenic temperature and high radiation on the Europa and Lunar surface. The optimum placement of these antennas will also be discussed to maximize the coverage hours and data volume per day. All metal meta surface antennas have been designed for Ku band radar and are currently being used for ice sounding measurements. These antennas form an integral part of the development for future space missions

Title Compact circularly polarized antenna designs for RF energy harvesting system
Abstract :
Global demand for energy has grown rapidly in recent years. To meet the long-term demand of global energy, different techniques of wireless energy harvesting were introduced. Harvesting RF energy is an alternative solution, especially with the advances and popularity of wireless communication devices. These communication devices are constantly transmitting RF energy, so RF energy harvesting paves a way to utilize the abundant scattered electromagnetic (EM) waves in our surroundings environment. The available EM waves (RF energy) can be in any polarizations, such as elliptical, linear, or circular. By using an appropriate receiving antenna, EM waves can be converted into electrical energy for low-powered devices, and thus, there is much focus put toward RF energy-harvesting (RFEH) systems, especially in the antenna designs. A CP antenna enables the system to harvest RF energy regardless of the device orientation as well as making the insensitive to polarization loss. The RF waves/energy that is found in the surrounding area can exist in any orientation and phase alignment, so CP antennas are more desirable for energy harvesting systems.

Title Dielectric Properties of Healthy Human Skin and Challenges towards Dermal Anomaly Detection using Electromagnetic Techniques
Abstract :
The subject talk aims to present the complex nature of the human body's largest organ (skin) in terms of its dielectric properties. Skin is the primary barrier to the external environment and protects vital organs from harmful organisms. Any malignancy damaging this first line of defense would require an urgent clinical response. Therefore, as a pre-requisite towards building an electromagnetic skin cancer detection system, it is necessary to understand the dielectric nature of healthy skin and its variation across multiple body regions. The talk will discuss the statistical relationship between the dielectric properties of measured dermal regions and various bio-features, such as skin pigmentation, body weight and gender, observed across 50 healthy volunteers. The observations are aimed at assisting the development of an electromagnetic skin cancer detection system by identifying the causes of dielectric variations across different dermal measurement conditions. The interactive session will also address the measurement challenges and proper characterization procedures of this heterogeneous biological tissue in the clinical environment.

Title Securing IoT: Antennas as Padlocks, Propagation as a Key
Abstract :
Physical layer (PHY-layer) security is a topic of paramount significance, as it attempts to restrict the physical areas towards which the communication is transmitted. While numerous cryptographic schemes have been implemented to secure communication in higher layers of telecommunication stack, the PHY-layer offers the unique possibility to link the cryptographic scheme to the physical location of transmitter/receiver.
Dynamic Directional Modulation (DM) is a key-less technique to increase privacy of the wireless communication using features of antenna and propagation. Its traditional implementations require bulky antenna arrays, which are impractical for compact Internet of Things (IoT) devices. The talk presents recent advances in beamforming-capable electrically small antennas, their use for on-body DM. To support the low-power aspect of IoT, it demonstrates dynamic DM scheme with single RF chain and simplified computational power. Lastly, it discusses the double-edged use of MIMO systems, which can be deployed by attacker for their advantage.

Title How to properly apply novel ideas to a conventional research domain—a journey from signal processing to compressive antenna arrays
Abstract :
High-impact scientific publications have been shown to be highly conventional, while also drawing inspiration from a few highly unexpected sources. Balancing novelty and conventionality is a tricky business. In this talk, we look at the case of compressive antenna arrays, and how a signal-processing concept went from being naively copied to antenna arrays, to inspiring a new type of antenna array that offers improved performance in conventional antenna-array terms.

Title PHY Layer Enhancements and Resource Allocation in mmWave and sub-THz
Abstract :
Based on the channel properties in mmWave and sub-THz, various physical layer enhancements are considered. Novel modulation and coding methods, sensing based on LiDAR to predict blockages and incorporation of RADAR sensing into communication system are among those. LiDAR / RADAR are considered as infrastructure based as opposed to vehicle mounted providing the base station – network with accurate position details enabling location based beamforming and facilitating beam management. Reconfigurable intelligent surfaces (RIS) can add to the more deterministic nature of the channel with suitable placement and how these are used effectively is an interesting avenue for research. In terms of resource allocation, instead of complex optimization implementations, we can consider machine learning based solutions in cell free massive MIMO systems. The challenge is to reduce complexity and facilitate a stable rate through suitable power control methods.
