SUMMARY:Seminar on Machine Learning\, Artificial Intelligence\, Neuro Imaging Focusing on Longevity and Dementia (MANIFOLD)
DESCRIPTION:Abstract\nBrain health is one of the key societal challenges for the 21st century\, and much progress has been made in understanding and treating brain health conditions\, aided by growing use of neuroimaging. Meanwhile\, artificial intelligence and machine learning (AI/ML) technologies have revolutionised many domains\, including healthcare. However\, there is still a translational gap between AI/ML methods and the use of neuroimaging to detect\, treat and care for people with neurodegenerative or neurodevelopmental conditions. My talk will provide an overview of the research of the MANIFOLD lab at UCL\, that aims to bridge this gap and provide clinically useful neuroimaging tools to improve brain health. I will focus on methods that emphasise the individual patient\, namely the brain-age paradigm and neuroanatomical normative modelling\, applied to Alzheimer’s disease and dementia with Lewy bodies and frontotemporal dementia. Beyond this\, I will talk about our research in explainable AI (XAI)\, AI/ML data fusion\, automated ML and accessible MRI using portable scanners and how we have or plan to apply these in studies of brain diseases. \nSpeaker\nProf. James COLE\nProfessor of Neuroimage Computing\,\nUCL Hawkes Institute and the Dementia Research Centre (DRC)\,\nUniversity College London (UCL) \nSpeaker’s Biography\nJames Cole is Professor of Neuroimage Computing at the UCL Hawkes Institute and the Dementia Research Centre (DRC) at University College London (UCL). His research interests include brain ageing\, neurological and psychiatric diseases\, with a particular focus on ageing\, neurodegeneration and dementia.

SUMMARY:RPG Seminar – Design of Novel Structured Light Beams in Optical Manipulation and Two-Photon Microscopy
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/6983793721?pwd=UjwaYARlhjvhUf7DDp3bMjbJnlhVbr.1 \nAbstract\nStructured illumination refers to a class of optical imaging methods in which the sample is illuminated with a controlled spatial light pattern rather than uniform illumination. By altering the illumination pattern\, it can facilitate the extraction of spatial or temporal information from the sample\, and may improve imaging performance such as resolution or acquisition speed. It also enables precise manipulation of microscopic objects through targeted light patterns. One example is the higher-order BBs generated by adding a vortex phase to the zero-order BBs and exhibiting a ring-shaped intensity distribution. Their characteristic length results in different trapping states of particles with different sizes\, which is of assistance to the size-sorting process. To this date\, there has been no research on high-order conveyor beams with a vortex modulation. In this study\, a spatial light modulator (SLM) is used to generate the ring-shaped conveyor beams. The beam profile is simulated and then confirmed with a two-photon microscopy system. The conveyor beam shows two alternating rings with an axial period. This technique opens a door to simultaneous optical manipulation of the particle’s OAM and longitudinal translation. The application of another class of beams\, axially encoded beams\, in multiphoton microscopy (MPM)\, will also be introduced. Combined with computational decoding\, these beams enable axially parallel excitation (APEX) that extends per-plane exposure without slowing acquisition or requiring higher power. High-speed volumetric MPM with improved contrast will be demonstrated. \nSpeaker\nMs. Minghui SHI\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nSpeaker’s Biography\nMinghui SHI received the B.S. degree in optical information science and technology from the Beijing University of Technology\, Beijing\, China\, in 2021. She is currently working toward the Ph.D. degree with the Department of Electrical and Electronic Engineering\, The University of Hong Kong\, Hong Kong. Her research interests include structured illumination\, fluorescence imaging\, and mid-infrared laser applications. \nOrganiser\nProf. Kenneth K.Y.

SUMMARY:RPG Seminar – Design of High-Performance and Energy-Efficient AI Accelerator for Edge Computing
DESCRIPTION:Abstract\nThis seminar provides a systematic showcase of our end-to-end energy-efficient solutions in AI accelerator design\, spanning from the foundational compute unit to specialized architectures and large model deployment on edge devices. We begin by introducing a novel Reconfigurable Processing Element (PE)\, the core compute unit designed to support multiple floating-point (e.g.\, BF16\, FP16) and fixed-point (e.g.\, INT8\, INT4) Multiply-Accumulate (MAC) operations with 100% hardware utilization\, achieving exceptional energy efficiency exceeding 1700 GFLOPS/W for deep learning tasks. Subsequently\, addressing the need for extreme efficiency in edge vision\, we present dedicated\, multiplication-free Look-Up Table (LUT) accelerators like BDLUT (for blind denoising)\, EdgeLUT (for all fixed-resolution image restoration) and ScaleLUT (for real-time 4K super-resolution). These designs replace traditional convolutional operations with efficient LUT inference\, resulting in significantly lower hardware and power consumption. Finally\, we focus on high-efficiency acceleration for complex modern AI models: we propose the QuadINR framework\, which utilizes hardware-efficient piecewise quadratic activation functions for Implicit Neural Representations (INR). For Large Language Models (LLMs)\, EdgeLLM is a highly efficient CPU-FPGA heterogeneous accelerator that employs a mixed-precision PE array (FP16/FP16 and FP16/INT4) and a unified data parallelism scheme\, successfully tackling LLM deployment challenges to achieve up to 1.91x higher throughput and 7.55x better energy efficiency than commercial GPUs. In summary\, this presentation offers a comprehensive view of our complete technological roadmap in the world of efficient AI chips\, achieved through co-optimization of hardware and algorithms\, to realize high-performance and energy-efficient AI acceleration for edge computing. \nSpeaker\nMr. Boyu Li\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nBoyu Li is a Ph.D. candidate in the Department of Electrical and Electronic Engineering at The University of Hong Kong\, under the supervision of Professor Ngai Wong. His research focuses on deep learning\, reconfigurable computing\, and the design of AI accelerators. \nOrganiser\nProf. Ngai Wong\nDepartment of Electrical and Electronic Engineering\, The University of Hong Kong \nAll are welcome.

SUMMARY:Seminar on An Update on Machine Learning for Communication Networks
DESCRIPTION:Abstract\nThe speaker aims to provide an update on recent progress by his research team on machine learning for communication networks. If time permits\, he will also highlight his work on distributed quantum computing and quantum machine learning. \nEfficient allocation of limited resources to competing demands is a crucial issue in the design and management of communication networks. In this seminar\, the speaker will first introduce a new reinforcement-learning (RL) technique for achieving optimal resource allocation in networks with periodic traffic patterns. The effectiveness of this method will be demonstrated through numerical examples. \nIn addition\, a new RL technique will be presented that separates representation learning from RL to enable fully decentralised learning in partially observable multi-agent settings. The approach relies on learned beliefs over the underlying system state. A belief model is first trained by using complete environment information\, which is then used by a state-based RL algorithm using distributed\, local observations only. A set of partially observable environments is constructed\, and the efficacy of this new approach is shown and compared to relevant benchmarks. \nIf time permits\, the speaker will also highlight his recent work on distributed quantum computing and quantum machine learning. \nSpeaker\nProf. Kin K.

SUMMARY:RPG Seminar – Towards End-to-End Visual Generation: from Matching to Evaluation
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/91953486299?pwd=lEW6N6JKhmAHLoS38VohufbEoJyJtw.1 \nAbstract\nThis seminar examines how modern image generation models can be redesigned to achieve both high fidelity and high efficiency under flexible inference budgets. I will begin with a brief overview of generative modeling\, focusing on diffusion models and related flow-based formulations. While these approaches deliver strong stability and visual quality\, they typically rely on iterative reverse-time sampling and therefore require many sequential steps at inference\, which limits practicality in latency- or compute-constrained settings. \nNext\, I will discuss mainstream strategies for reducing inference steps—such as distillation and consistency-style objectives—and highlight their common limitations\, including reliance on strong pretrained teachers or difficulties in stable training from scratch at scale. Building on this\, I will introduce an end-to-end perspective that unifies matching and evaluation within a single training framework. In particular\, I will present the idea of self-evaluation as a training signal: the model learns from data-driven local supervision while simultaneously assessing its own generated samples using its current estimates\, effectively acting as a dynamic self-teacher. This coupling bridges local learning and global distribution alignment\, enabling any-step text-to-image inference that degrades gracefully with fewer steps and improves monotonically as more steps are allocated. \nSpeaker\nMr. Xin Yu\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nMr. Xin Yu is currently pursuing the Ph.D. degree with the Department of Electrical and Electronic Engineering\, supervised by Professor Xiaojuan Qi. He received his bachelor’s degree in Mathematics and Applied Mathematics from Sun Yat-sen University in 2021. His research interests primarily lie in generative models for computer vision. \nOrganiser\nProf. Xiaojuan Qi\nDepartment of Electrical and Electronic Engineering\, The University of Hong Kong \nAll are welcome.

SUMMARY:RPG Seminar – Bridging Visual Generation and Understanding in Native MLLMs with a Unified Visual Tokenizer
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/98499142544?pwd=zvVs3BqWzIzCA071Dqq2rYW7vIAqj7.1 \nAbstract\nThe advent of GPT-4o highlights the immense potential of Multimodal Large Language Models (MLLMs) with native visual generation capabilities. These unified models offer precise control in multimodal interactions\, enabling exceptional fluency in tasks such as multi-turn image editing and visual in-context learning. However\, a fundamental dilemma remains in the choice of visual tokenizers for unified MLLMs – e.g.\, semantic tokenizers like CLIP excel in multimodal understanding but complicates generative modeling due to its high-dimensional\, continuous feature space; Conversely\, VQVAE tokenizers fit autoregressive generation but struggles to capture essential semantics for understanding. \nThis seminar explores how to design a unified visual tokenizer to bridge the gap in multimodal generation and understanding. Recent studies attempt to address this by connecting the training of VQVAE (for autoregressive generation) and CLIP (for understanding). However\, directly combining these training objectives has been observed to cause severe loss conflicts.  We will show that reconstruction and semantic supervision do not inherently conflict. Instead\, the underlying bottleneck stems from limited representational capacity of discrete token space. Building on these insights\, we introduce UniTok\, a unified tokenizer featuring a novel multi-codebook quantization mechanism that effectively scales up the vocabulary size and bottleneck dimension. \nSpeaker\nMr. Chuofan Ma\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nMr. Chuofan Ma is currently pursuing the Ph.D. degree with the Department of Electrical and Electronic Engineering\, supervised by Professor Xiaojuan Qi.

SUMMARY:RPG Seminar – Mamba model acceleration on RRAM-Based Compute-in-Memory (CIM) Systems integrated with Selective State-Space Streaming
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/97793742616?pwd=YIyYlokhzOsap3IvbsbwmfaHVHFoin.1 \nAbstract\nAs Generative AI shifts toward handling massive context windows\, the quadratic complexity of Transformer architecture has become a significant bottleneck. State Space Models (SSMs)\, particularly Mamba\, have emerged as a promising solution\, offering linear-time scaling and superior efficiency. However\, the unique computational duality of SSMs—requiring both memory-intensive projections and agile\, input-dependent state updates—presents new challenges that traditional von Neumann architectures and GPUs struggle to address efficiently. \nThis seminar explores the evolution of efficient sequence modeling and the critical hardware innovations required to support it. We will examine the “Memory Wall” problem in modern AI deployment and introduce Compute-in-Memory (CIM) using Resistive RAM (RRAM) as a paradigm shift to minimize data movement. The discussion will focus on the principles of hardware-software co-design\, illustrating how tailored architecture can bridge the gap between memory-bound operations and dynamic recursions. By integrating specialized streaming dataflows with non-volatile memory technologies\, we can define a new computational fabric capable of enabling the next generation of energy-efficient edge AI. \nSpeaker\nMr. Mingzi Li\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nMr. Mingzi Li is currently pursuing the Ph.D. degree with the Department of Electrical and Electronic Engineering\, supervised by Professor Han Wang.

SUMMARY:Seminar on Semiconductor Nanodimer as a Partially Open Terahertz Resonator
DESCRIPTION:The event has been rescheduled to December 8\, 2025 (Monday). \nAbstract\nResonators are often the first apparatus to be constructed and thoroughly investigated when a new region of the spectrum is being explored. From the days of spark-gap generators in early radio transmission to the more recent maser and laser era\, resonant systems have always been essential in enabling a given range of the spectrum to become accessible to electronic communication and instrument applications. With the current interest in terahertz technology\, it would appear logical to search for structures or physical processes that exhibit natural resonances in the terahertz range. Plasma resonance in extrinsic semiconductors can be designed to exhibit field concentration and guiding characteristics that are impetus for sensing and circuitry applications for research and development of terahertz technology. While a single semiconductor nanoparticle (SNP) does exhibit surface plasmon resonance\, the local terahertz field garnered near the two poles of an SNP lacks symmetry and is strongly influenced by the embedding medium. On the other hand\, a semiconductor nanodimer (SND) formed by two SNPs with a gap in between them offers a more secluded environment for field enhancement with better symmetry in field distribution. Considerable attention has been given to metallic nanodimers\, leading to their roles in sensing and antenna applications. On the other hand\, investigations on SNP and SND are currently in the early stage. The salient characteristics of SNDs formed with matched and dissimilar SNPs are discussed in light of their potential for terahertz components and systems development. \nSpeaker\nProf. Thomas WONG\nProfessor Emeritus\,\nDepartment of Electrical and Computer Engineering\,\nIllinois Institute of Technology\nAdjunct Professor of HKU-EEE \nSpeaker’s Biography\nThomas WONG received the B.Sc. degree from the University of Hong Kong\, and the M.S. and Ph.D. degrees from Northwestern University\, all degrees being in Electrical Engineering.

SUMMARY:RPG Seminar – A Hybrid Iterative Framework for AC Unit Commitment: Integrating Global Linearization Updates with Local Constraint Corrections
DESCRIPTION:Zoom Link:  https://hku.zoom.us/j/96462551842?pwd=MFNEYU1qcmZzeE9Rby9aRVZLQ0RZdz09 \nAbstract\nTo address the computational challenges of AC Unit Commitment (AC-UC)\, this paper proposes a hybrid iterative framework that decomposes the MINLP model into a linearized MILP master problem and an exact AC feasibility check. The approach integrates Taylor-expansion-based linearization with a novel switching strategy that coordinates global updates for initial geometric alignment and local constraint corrections for subsequent stability. By freezing the Jacobian matrix after the initial phase\, the method effectively mitigates integer oscillation. Case studies on IEEE standard test systems verify that the proposed method significantly reduces linearization errors\, improves the quality of unit commitment decisions\, minimizes physical violations and operating costs\, and decreases the number of iterations required for convergence. \nSpeaker\nMiss Miao Cheng\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nMiao Cheng received her bachelor’s degree from Beihang University and her master’s degree from Tsinghua University\, both in electrical and electronic engineering.

SUMMARY:RPG Seminar – Planning and Operation Optimization of Electric-Coupled Systems for High-Speed Railways towards Flexibility and Resilience
DESCRIPTION:Zoom Link:  https://hku.zoom.us/j/97338207102 \nAbstract\nElectrified high-speed railways are emerging as major and spatially distributed electricity consumers in modern power systems\, and their traction demand is tightly coupled with train dynamics and timetable scheduling. With the increasing exploitation of renewable resource endowments along railway corridors\, electrified railways are evolving from pure loads into potential flexibility and resilience providers for low-carbon power systems. However\, this evolution also brings new challenges and opportunities. On the one hand\, existing models and operation strategies often treat high-speed railways as rigid electrical loads\, leading to simplified kinetic-electrical representations and limited utilization of flexibility arising from coordinated train control and energy management of electric-coupled traction power supply systems. On the other hand\, existing planning approaches for railway energy infrastructure remain largely economy-oriented and seldom incorporate explicit resilience criteria or the multi-stage couplings between energy supply adequacy and transportation service continuity. Hence\, for the first challenge\, we develop a unified kinetic-electrical coupling model together with a space-domain multi-phase pseudospectral coordination framework that jointly optimizes train trajectories and the operation of electric-coupled traction power supply systems with integrated photovoltaics and hybrid energy storage. The proposed method simultaneously accounts for detailed railway operating constraints and power system operating constraints within a numerically efficient optimal control formulation\, demonstrating reduced traction energy cost\, enhanced renewable utilization\, and mitigated power fluctuations at the grid interface compared with benchmark strategies. For the second challenge\, we propose a multi-stage resilience enhancement framework that integrates risk-aware capacity planning\, rolling emergency energy management\, and adaptive train control. A two-stage stochastic program with risk measurements is employed to co-optimize renewable\, storage\, and backup generation capacities under extreme grid outage and adverse weather scenarios\, while operational layers coordinate distributed resources and train trajectories in real time. Case studies show that the proposed framework can substantially improve both energy supply resilience and transportation service robustness with moderate additional cost\, highlighting electrified high-speed railways as promising flexibility and resilience resources in future power systems. \n \nSpeaker\nMr. Ruizhang Yang\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nRuizhang Yang received his B.S. and M.S. degree in Electrical Engineering from Huazhong University of Science and Technology\, China in 2017 and 2020\, respectively.

SUMMARY:RPG Seminar – Lightweight Blockchain for Spatially and Temporally Scalable Federated Learning in Edge Networks
DESCRIPTION:Zoom Link:  https://hku.zoom.us/j/97347520963?pwd=ohdjCe9kx6axOTFn2m2M9gsVojb2kG.1 \nAbstract\nFederated Learning (FL) has rapidly advanced as a foundational paradigm for realizing privacy-preserving intelligence in edge networks. However\, its real-world deployment is fundamentally challenged by two dimensions: spatial scalability across a large\, heterogeneous population of devices\, and temporal robustness over long-lived\, evolving learning processes. While blockchain technology offers inherent benefits like tamper-proof logging and decentralized trust\, its naïve integration with FL is often intractable. This intractability stems from complex communication topologies\, severe resource limitations\, and the increasing cost of maintaining and retrieving an ever-expanding\, shared knowledge base. \nThis seminar presents a unified view of lightweight blockchain designs systematically engineered to overcome these challenges. We introduce two novel systems: LiteChain and LiFeChain. LiteChain addresses spatial scalability in massive edge networks. Furthermore\, it incorporates a Comprehensive Byzantine Fault Tolerance (CBFT) consensus and a secure update mechanism to reduce end-to-end latency\, on-chain storage overhead. LiFeChain tackles the temporal dimension in Federated Lifelong Learning (FLL) for edge networks. It is combined with a Segmented Zero-knowledge Arbitration (Seg-ZA) protocol that enables efficient\, bidirectional model verification with minimal on-chain disclosure. Implemented as a plug-and-play component in representative FLL frameworks\, LiFeChain significantly enhances model robustness against long-term\, cumulative attacks while sustaining efficiency and scalability. \nThese works demonstrate a systematic methodology for redesigning blockchain architectures to support FL that is simultaneously capable of scaling out in space and enduring over time within highly constrained edge networks. \nSpeaker\nMiss Handi Chen\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nHandi Chen received the B.E. degree in network engineering from Tianjin University of Since and Technology in 2019\, and the M.E. degree in network engineering from the Dalian University of Technology in 2022.

SUMMARY:RPG Seminar – Foldable Inverted Perovskite Solar Cells Enabled by Dual Strain Release
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/8157366378?omn=98994435560 \nAbstract\nThe poor mechanical durability of perovskite films due to the severe intrinsic strain\, and the brittle nature of the flexible ITO electrode hinder foldable perovskite solar cells (F-PSCs) realization. In this talk\, the strategy of region-dependent microscopic and macroscopic strain suppression is demonstrated to achieve efficient F-PSCs on silver nanowires (AgNWs) electrodes. Fundamentally\, by introducing the region-dependent modification approach of functionalized polymer incorporation\, the significant release of microscopic strain in perovskite film is demonstrated by effectively suppressing defects at places with crystallization orientation variation of perovskite surface/grain boundaries. Equally important\, the gradient macroscopic strain is simultaneously eliminated by inhibiting the FA+ (formamidinum) gradient distribution in perovskite film’s depth direction. The two-strain relaxations greatly enhance the mechanical durability of perovskite film\, while also improving phase stability and suppressing ion migration. Finally\, efficient F-PSCs (23% PCE) with remarkable foldability is realized.\n \nSpeaker\nMr. Biao Zhou\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nZHOU Biao received the M.S. degree from Sichuan University in 2022.

SUMMARY:RPG Seminar – Direct Data-driven Control for Marine Vehicles
DESCRIPTION:Zoom Link:  https://hku.zoom.us/j/91408893076?pwd=5rgw1jrHuqg5lKfbIba5O5OsJGZbdf.1 \nAbstract\nMarine vehicles play an essential role in modern ocean operations\, where reliable motion control is critical for safe\, precise\, and efficient task execution. This talk presents a direct data-driven control framework that synthesizes controllers directly from input–state–output data\, thereby bypassing the need for complex hydrodynamic modeling and system identification. We address two fundamental motion control problems: autopilot (heading) control and trajectory tracking. For the autopilot problem\, we design a linear state-feedback controller at each time step by solving a set of data-dependent linear matrix inequalities. The resulting controller guarantees internal stability together with a prescribed level of disturbance attenuation\, and we further establish iterative feasibility of the underlying optimization problem\, enabling real-time implementation. For the more challenging trajectory-tracking problem—which requires simultaneous regulation of heading and position and involves a kinetic subsystem with many unknown hydrodynamic parameters—we first derive a data-driven representation of the vessel kinetics. Building on this representation\, we formulate a robust data-based optimization problem for controller synthesis that ensures global uniform ultimate boundedness of the closed-loop system. \nSpeaker\nMr. Jinjiang Li\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nJinjiang Li is a Ph.D. student in the Department of Electrical and Electronic Engineering.

SUMMARY:RPG Seminar – Data-Driven Intelligence and Energy-Aware Edge–Cloud Collaboration for IoT Systems
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/92852691758?pwd=ApSXYeoYJk3Y5MLcS33duwNe4ZyTnM.1 \nAbstract\nThe rapid growth of Internet-of-Things (IoT) deployments\, combined with increasing adoption of edge computing\, has created substantial challenges in energy efficiency\, real-time intelligence\, and collaborative resource management. IoT systems—ranging from smart buildings to cellular base stations—exhibit highly dynamic\, heterogeneous\, and energy-intensive behaviors that require new data-driven methods for prediction and optimization. This seminar investigates a unified edge–cloud collaborative framework that advances intelligent energy management across large-scale IoT environments. The first part presents HALO\, a transformer-based HVAC load forecasting framework designed to address intrinsic complexities in real-world building operations. HALO incorporates adaptive preprocessing\, a multi-scale local–global attention architecture\, and a scale-fusion mechanism to handle data variability\, multi-temporal fluctuations\, and electronic sensor anomalies. Evaluations on six buildings with diverse climates and user patterns demonstrate that HALO significantly improves 24-hour load forecasting accuracy compared to state-of-the-art baselines. The second part introduces PATNet\, an incentive-aware framework for energy–computation collaboration in mobile edge computing (MEC) networks. Leveraging an Overlapping Coalition Formation model\, PATNet jointly optimizes MEC workload offloading\, backup-battery utilization\, and participation in real-world power adjustment (PA) incentive programs. Experiments using large-scale operational traces from up to 118\,000 base stations show that PATNet increases utility significantly over existing strategies while maintaining service reliability. Together\, HALO and PATNet demonstrate how data-driven prediction and energy-aware collaboration can be seamlessly integrated to enhance the intelligence\, efficiency\, and sustainability of next-generation IoT systems. \nSpeaker\nMs. Cheng Pan\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nCheng Pan is currently pursuing her Ph.D. in Electrical and Electronic Engineering at the University of Hong Kong under the supervision of Prof. Edith Ngai.

SUMMARY:RPG Seminar – Ultrafast quantum sensing enabled by in-sensor computing
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/96428082165?pwd=Ra2k3v7nAa8r90G3Ntje8n6uspb3V4.1 \nAbstract\nNitrogen Vacancy (NV) center\, an optically addressable defect in diamond\, has been explored as a promising sensing platform\, due to its exceptional electronic spin properties at the room temperature. The widefield quantum sensing\, leveraging this special property\, allows for parallel readout of spatially resolved NV fluorescence\, and therefore offers enormous potential in diverse fields\, including temperature and magnetic field capturing. Conventional widefield quantum sensing method relying on traditional frame-based cameras\, however\, is usually limited in its sensing speed because it generates a massive amount of data in the form of image frames that needs to be transferred from the camera sensors for further processing. \nThis seminar will talk about a new method that realizes the ultrafast widefield quantum sensing by leveraging the bio-inspired in-sensor processing capability. The designed intelligent system mimics the working process of human eyes that merges signal detecting and processing together\, and the resonance frequencies then can be extracted during the sensing period while no redundant raw data needs to be transferred outside\, and thus an ultrashort sensing time (~ 10 µs in theory) can be achieved. \nSpeaker\nMr. Du Zhiyuan\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nDu Zhiyuan received his B.S. and M.S. degree from the School of Optics and Photonics at Beijing Institute of Technology (BIT)\, China in 2016 and 2019\, respectively.

SUMMARY:Seminar on Bi-Static Sensing for Next Generation Perceptive Communication Networks: Technologies and Applications
DESCRIPTION:The event time has been revised to start at 2:00 pm. \nAbstract\nIntegrated Sensing and Communications (ISAC) represents a paradigm shift from conventional communication-only networks toward systems that natively integrate radar-like sensing capabilities. It has become a foundational technology for next-generation wireless systems\, including Wi-Fi and 6G networks. \nBi-static sensing\, where a sensing receiver exploits signals transmitted by another node\, naturally aligns with the topology of communication networks. It circumvents the stringent full-duplex requirements of mono-static sensing and offers enhanced spatial sensing diversity. However\, clock (Local oscillating signal) asynchronism\, which inherently exists among spatially separated communication nodes\, poses a central and challenging problem. It can cause ranging ambiguities and disrupt coherent processing of discontinuous measurements\, such as those required for Doppler frequency estimation. If effectively resolved\, sensing could be seamlessly realised within existing communication infrastructures\, requiring minimal hardware or architectural modifications. \nThis talk explores advanced techniques for tackling clock asynchronism in bi-static sensing\, with a focus on efficient single-receiver-based solutions. The problem will first be introduced in the context of 6G perceptive mobile networks\, followed by a comprehensive overview of recent methods applicable to both multi-antenna and single-antenna configurations. I will then present our latest sensing applications developed using these techniques\, including moving-object tracking\, respiration and heartbeat monitoring\, behavior recognition\, and environmental sensing such as rainfall and water-level detection. The talk concludes by outlining key open challenges and future research directions in this rapidly evolving field. \nSpeaker\nProf. Andrew ZHANG\nUniversity of Technology Sydney \nSpeaker’s Biography\nProf. J.

SUMMARY:RPG Seminar – Enhancing Ultrasound Shear Wave Elasticity Imaging Through Spectral Methods and Optimized Sparse Arrays
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/97206601239?pwd=ZZh3WRdq0GpwIlSkVT1UP19HuJD2XQ.1 \nAbstract\nShear wave elasticity imaging (SWEI) is a widely-used technique for quantifying the stiffness of biological tissues. Tissue stiffness varies with pathological processes\, for instance\, local tissue stiffening due to increased stromal density in cancer. However\, there still exist some challenges in SWEI. Specifically\, on the one hand\, the performance of current shear wave speed estimation methods still suffer from biased estimations or time-consuming computations\, and are prone to wave distortions in in vivo cases. On the other hand\, the 2-D nature of conventional SWEI leads to a lack of comprehensive analysis for 3-D shear wave propagation\, for instance\, in anisotropic tissues.  Hence\, for the first challenge\, we have proposed a parameter-free\, robust\, and efficient group SWS estimation method coined as Fourier energy spectrum centroid (FESC). The proposed FESC method is based on the center of mass in ω − k space. It has been evaluated on data from computer simulations with additive Gaussian noise\, a commercial elasticity phantom\, an ex vivo pig liver\, and in vivo biceps brachii muscles of three young healthy male subjects. The FESC method has been compared with four other benchmark methods. Statistical results showed that our FESC method exhibited excellent performance compared the other benchmark methods in terms of precision and computational efficiency. For the second challenge\, due to the instantaneity of shear wave propagation and the adverse effect of high sidelobes on shear wave imaging. We initially have designed an on-grid quasi-flatten side-lobe (Q-Flats) 2D sparse array with 252 activated elements\, which aims to achieve as high contrast performance as possible under the limits of resolution and maximum number of independent channels (i.e.\, 256). The imaging performance of the Q-Flats array has been evaluated using Field II simulations in a multi-angle steered diverging wave transmission scheme. It is demonstrated that the Q-Flats finds a good trade-off among resolution\, contrast\, and number of activated elements. \nSpeaker\nMr. Xi Zhang\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nXi Zhang received the B.S. degree in Electrical Engineering and its Automation from Huazhong University of Science and Technology in 2017 and the Master degree in Biomedical engineering  from Tsinghua university in 2020\, respectively.

SUMMARY:RPG Seminar – Stretchable\, Enhancement-mode PEDOT:PSS Organic Electrochemical Transistors
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/97481664242 \nAbstract\nThe rise of wearable and implantable bioelectronics necessitates stretchable electronic devices and systems to seamlessly integrate with soft biological environments. Stretchable organic electrochemical transistors (OECTs)\, based on conducting polymer poly (3\, 4-ethylenedioxythiophene) doped with polystyrene sulfonate (PEDOT: PSS)\, have emerged as a promising candidate because of their combined high stability and high transconductance. However\, a stretchable\, enhancement-mode PEDOT: PSS OECT (SE-OECT) is still missing\, limiting the development of complementary and low-power integration systems. In this Letter\, we report SE-OECTs. The devices showed typical enhancement-mode transistor behaviors with standby power as low as 0.1 μW while maintaining stable performance after 1000 cyclic tests within 50% strain. \nSpeaker\nMiss Yan Wang\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nYan Wang received her B.Sc in Chemistry from Nankai University.

SUMMARY:RPG Seminar – Efficient Learning for Image Restoration and Single-Photon Imaging without Clean Data
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/92646013468?pwd=lkoH511LkjLHtW43awHeBpEVnLfZ7b.1 \nAbstract\nSupervised deep learning has revolutionized computational imaging but relies heavily on vast datasets of clean\, ground-truth images\, which are often challenging to acquire in practice. This seminar presents a series of methods that break this dependency by embracing weakly-supervised and unsupervised learning\, directly addressing the challenge of learning without clean data. First\, I will introduce a Fourier-based statistical equivalence between learning with noisy targets and clean targets. Building on this\, I will present a weakly supervised framework for diverse image restoration tasks\, along with two unsupervised denoising methods specifically designed for pixel-wise and stripe-wise noise. Finally\, I will introduce a physics-informed unsupervised framework that can enable image restoration learning for single photon imaging with only the training data degraded by the blurring effect\, Poisson noise\, and readout noise. Collectively\, this seminar demonstrates powerful and flexible learning paradigms that advance the computational imaging for scenarios where clean data is unavailable. \nSpeaker\nMr. Haosen Liu\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nHaosen Liu received his B.Sc. and M.S. degrees from Huazhong University of Science and Technology\, and is currently a fourth-year Ph.D. candidate in the Department of Electrical and Electronic Engineering at The University of Hong Kong under the supervision of Prof. Edmund Y.

SUMMARY:RPG Seminar – Brain-inspired Random Memristors Pruning for Input-aware Dynamic SNN
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/96497087839?pwd=5X1msaxhZNiH87SuzGTPgQHZILJmgi.1 \nAbstract\nMachine learning has advanced unprecedentedly\, exemplified by GPT-4 and SORA. However\, they cannot parallel human brains in efficiency and adaptability due to differences in signal representation\, optimization\, run-time reconfigurability\, and hardware architecture. To address these challenges\, we introduce PRIME—a pruning optimization for input-aware dynamic memristive spiking neural networks. PRIME leverages spiking neurons to emulate biological spiking mechanisms and optimizes the topology of random memristive SNNs\, mitigating memristor programming stochasticity. Additionally\, it employs an input-aware early-stop policy to reduce latency and memristive in-memory computing to alleviate the von Neumann bottleneck. Validated on a memristor-based macro\, PRIME achieves competitive classification accuracy and superior energy efficiency. \nSpeaker\nMr. Bo Wang\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nBo Wang received B.Eng. degree in Power Engineering\, Beihang University\, Beijing\, China\, in 2020\, and M.Eng. degree in Pattern Recognition and Intelligent Systems\, Beihang University\, Beijing\, China\, in 2022.

SUMMARY:RPG Seminar – High-throughput Neuromorphic Computational Imaging
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/99712347936?pwd=P2oHpewBKizDaTJNY9m4YowNQLZfaP.1 \nAbstract\nHigh-throughput dynamic imaging must recover fine spatial structure under rapid motion\, yet no conventional sensor can fully overcome the trade-offs between spatial resolution\, temporal resolution\, and motion-induced degradation. Frame sensors inevitably blur fast dynamics due to global integration\, while event sensors\, although extremely fast and high-dynamic-range\, provide only local 1-bit temporal changes and lack global spatial context. These sensing limitations fundamentally constrain applications ranging from defect inspection to phase-flow analysis. In this seminar\, I will present a neuromorphic computational imaging paradigm\, Neuromorphic Super-Resolution (NeuroSR)\, that addresses these limitations through physics-informed spatio-temporal feature inference. NeuroSR unifies the complementary measurements of frames and events into a fully differentiable architecture\, enabling high space–time resolved reconstruction and direct inference of physical structure such as motion blur kernels or coherent wave propagation. To illustrate the generality of this paradigm\, I will also introduce Neuromorphic Wave-Normal Sensing (NeuroSH) as a representative white-box example. NeuroSH demonstrates how asynchronous event cues can recover large-gradient wavefront information and surpass classical spot-overlapping constraints in dynamic wavefront sensing systems. Together\, these results highlight a unified neuromorphic approach that transforms both dynamic imaging and physical-structure inference\, enabling ultrafast defect inspection\, large-gradient wavefront analysis\, and high-throughput computational imaging well beyond the limits of conventional sensors. \nSpeaker\nMr. Chutian Wang\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nChutian Wang received the B.S. degree from the University of Science & Technology Beijing in 2020\, and the M.S. degree at Imperial College London in 2021.

SUMMARY:RPG Seminar – Trustworthy data sharing in power systems via blockchain
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/99852061481?pwd=QAsfylVs3cR4U1q4B4fczaBQpbyzKl.1 \nAbstract\nWith the digitalization of smart grids\, data becomes vital for advanced applications like load forecasting\, energy management\, and demand response. To unlock its full potential\, the critical challenge becomes how to build a trustworthy data-sharing framework for diverse stakeholders. Blockchain stands out as a promising solution. In this report\, we introduce a comprehensive framework to support both direct and implicit sharing methods via blockchain. For direct sharing\, we introduce a blockchain based searchable encryption for secure data retrieval from the cloud. For implicit sharing\, we propose a blockchain assisted federated framework to achieve collaborated training. To realistically deploy blockchain within existing infrastructure\, an optimization approach for node deployment is proposed to ensure practical implementation. Through this series of framework constructions\, we demonstrate the significant potential of blockchain applications in building a secure and efficient data-sharing ecosystem for the next generation of smart grids. \n  \nSpeaker\nMr. Ruiyang Yao\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nRuiyang Yao received the integrated master’s degree in mathematics from University of Oxford in 2021.

SUMMARY:RPG Seminar – On the Understanding of Uncertainty in Load Forecasting
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/92603659701 \nAbstract\nIn the context of digital transformation of the energy system\, how to effectively manage and quantify the uncertainty in forecasting has become a key bottleneck that restricts its reliable operation. This report will introduce our systematic work in the field of probabilistic load forecasting\, dedicated to addressing this core challenge. Our research establishes a complete solution around uncertainty\, covering three key aspects: firstly\, data preprocessing\, aimed at reducing the uncertainty of raw data; Next is model construction\, which precisely quantifies the uncertainty of predictions through innovative deep learning models; Finally\, the model explanation provides a unified and clear explanation framework for the probabilistic forecasting model of the “black box”. Through this series of studies\, we have not only significantly improved forecasting accuracy\, but also developed an open-source toolkit aimed at promoting the practical application of high reliability load forecasting technology in future energy systems. \nSpeaker\nMr Zhixian Wang\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nZhixian Wang received the B.S. degree in Statistics from The University of Science and Technology of China in 2022.

SUMMARY:RPG Seminar – Generative AI-empowered Time Series Synthesis in Smart Grids
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/94936719507?pwd=ceXhzS1htWuwj8oG0vJGQLS3JMpVwF.1 \nAbstract\nThe reliable operation and strategic planning of smart grids are critically dependent on high-fidelity time series data. However\, the increasing stochasticity of both energy supply and demand challenges conventional analytical methods\, exacerbated by potential extreme scenarios. This research posits Generative Artificial Intelligence (AI) as a transformative approach\, empowering not only the synthesis of realistic load/renewable energy time series\, but also their conditional generation for predictive analysis. This seminar will go through time series generation on both the supply and demand sides\, and then investigate the refinement for the generated data. Finally\, a Python library\, GenTS\, is constructed to provide a unified framework for benchmarking generative time series models under various tasks. \nSpeaker\nMr. Chenxi Wang\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nChenxi Wang received the B.S. degree in Electrical Engineering from South China University of Technology in 2022.
