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:Seminar on Automatic Rank Determination for Low-Rank Adaptation via Submodular Function Maximisation
DESCRIPTION:Abstract\nIn this talk\, we will introduce SubLoRA\, a rank determination method for Low-Rank Adaptation (LoRA) based on submodular function maximisation. In contrast to prior approaches\, such as AdaLoRA\, that rely on first-order (linearised) approximations of the loss function\, SubLoRA utilises second-order information to capture the potentially complex loss landscape by incorporating the Hessian matrix. We show that the linearization becomes inaccurate and ill-conditioned when the LoRA parameters have been well optimised\, motivating the need for a more reliable and nuanced second-order formulation. To this end\, we reformulate the rank determination problem as a combinatorial optimisation problem with a quadratic objective. However\, solving this problem exactly is NP-hard in general. To overcome the computational challenge\, we introduce a submodular function maximisation framework and devise a greedy algorithm with approximation guarantees. We derive a sufficient and necessary condition under which the rank-determination objective becomes submodular\, and construct a closed-form projection of the Hessian matrix that satisfies this condition while maintaining computational efficiency. Our method combines solid theoretical foundations\, second-order accuracy\, and practical computational efficiency. We further extend SubLoRA to a joint optimisation setting\, alternating between LoRA parameter updates and rank determination under a rank budget constraint. Extensive experiments on fine-tuning physics-informed neural networks (PINNs) for solving partial differential equations (PDEs) demonstrate the effectiveness of our approach. Results show that SubLoRA outperforms existing methods in both rank determination and joint training performance. \nSpeaker\nDr. Yihang GAO\nDepartment of Mathematics\,\nNational University of Singapore (NUS)\, Singapore \nSpeaker’s Biography\nYihang GAO is currently a Research Fellow in the Department of Mathematics at the National University of Singapore (NUS)\, Singapore.

SUMMARY:RPG Seminar – Incentive Mechanism Design for Split Federated Learning
DESCRIPTION:Abstract\nSplit Federated Learning (SFL) combines computational efficiency with privacy preservation\, but existing incentive mechanisms assume uniform cut-layer configurations across clients. This seminar presents a novel incentive mechanism that accounts for heterogeneous cut layer selections in SFL systems. \nWe formulate the problem as a Stackelberg game and derive theoretical convergence guarantees. The proposed mechanism provably achieves equilibrium with desirable strategic properties. Experimental results demonstrate significant improvements in participation rates\, model accuracy\, and resource efficiency compared to existing approaches. \nSpeaker\nMs. Xi Lin\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nMs. Xi Lin is an Mphil student in the Department of Electrical and Electronic Engineering at The University of Hong Kong\, supervised by Prof. Xianhao Chen.

SUMMARY:Seminar on Quantum Dot Nanocrystal Based Optoelectronic Devices and Infrared Image Sensors
DESCRIPTION:Abstract\nColloidal semiconductor quantum dot nanocrystals (QD NCs) have been shown to be promising materials for electronic and optoelectronic device applications because of their unique size dependent properties and solution processability. We develop a systematic methods to engineer the surface chemistry of quantum dot nanocrystals to control the charge carrier statistics as well as optical properties. We fabricate QD based infrared photodetectors (PDs) by examining and modifying the charge carrier transport and injection and by designing the structures of the nanocrystal based devices. Combinational studies have been conducted to improve the responsivity\, linear dynamic range\, noise\, detectivity of the PDs. A new patterning method is introduced by engineering the surface states of QDs\, achieving the high resolution devices. Newly developed patterning method is compatible with conventional photolithography process based on all‐solution processes. We introduce the pixel based and pixel-less image sensors with photomultiplication process in QD thin films. Finally\, the strategy to incorporate various NCs and QDs into multi-functional devices and system is discussed. \nSpeaker\nProf. Soong Ju OH\nDepartment of Materials Science and Engineering\,\nKorea University \nSpeaker’s Biography\nProf. Soong Ju OH obtained B.S. degree in Materials Science and Engineering from Korea University in 2007\, and received his Ph.D degree in Materials Science and Engineering from the University of Pennsylvania.

SUMMARY:Seminar on Approaches to Modelling and Analysis of Sustainable Power Networks
DESCRIPTION:Abstract\nDue to the evident climate change and environmental pressures the future power/energy systems will have to operate\, sooner rather than later\, in a net-zero environment. This will manifest in a mix of wide range of electricity generation\, storage and demand technologies (increasingly power electronics interfaced); blurred boundaries between transmission and distribution system; significantly higher reliance on the use of legacy and measurement data including global signals for system identification\, characterisation\, and control and Information and Communication Technology embedded within the power system network and its components. The key characteristics of such a complex system\, would certainly be proliferation of power electronic devices in different shapes and forms and for different purposes\, increased uncertainties in system operation and parameters and much larger reliance on the use of measurement and other data collected. \nThis presentation will first briefly introduce some of the key characteristics of net-zero power systems characterised by high proliferation of power electronics (PE) based transmission and control devices/technologies and power electronics connected low carbon technologies (generation\, demand and storage). It will then discuss the control and operation advantages that introduction of these technologies offers\, reflect on resulting challenges that their introduction in the power system poses and elaborate on the need for holistic (multi parameter\, multi criteria and multi system) approach to solving the identified challenges. \nThis will be followed by illustrative examples of both\, advantages and disadvantages resulting from proliferation of power electronics based technologies on power system’s steady state and dynamic performance and examples of a holistic approach to multicriteria multi system analysis of net zero power systems focusing on applications of nondeterministic approaches\, use of data analytics and machine learning. \nThe presentation will conclude with recommendations for overcoming the identified challenges and harnessing the full potential of power electronics based or interfaced technologies for transition to net-zero power systems in foreseeable future. \nSpeaker\nProf. Jovica V MILANOVIĆ\nFormer Head of Department (Dean)\,\nElectrical and Electronic Engineering\,\nThe University of Manchester \nSpeaker’s Biography\nProf. Jovica V MILANOVIĆ received Dipl.Ing. and M.Sc. degrees from the University of Belgrade\, Yugoslavia\, Ph.D. degree from the University of Newcastle\, Australia\, and D.Sc. degree from The University of Manchester\, UK.

SUMMARY:Seminar on Distributed Optimisation Frameworks for Large-Scale Nonlinear Programming in Power Systems
DESCRIPTION:Abstract\nThe ongoing energy transition is challenging centralised power system paradigms by rapidly integrating distributed energy resources (DERs)\, which introduce significant supply-demand variability. This variability complicates grid management and necessitates enhanced coordination among operators. Centralised data aggregation further exacerbates privacy risks and strains the communication infrastructure as the proliferation of controllable devices increases.\nTo address these challenges\, this presentation introduces advances in distributed frameworks for nonconvex nonlinear programming (NLP). The first approach refines a distributed Sequential Quadratic Programming (SQP) framework that integrates the barrier method and Schur-complement-based communication reduction\, enabling efficient parallelisation through graph decomposition. Large-scale AC optimal power flow (OPF) benchmarks demonstrate its superiority over the centralised solver IPOPT. The framework solves problems with over 500\,000 variables at speeds 2–8 times faster than IPOPT on standard workstations while maintaining numerical robustness. The second approach leverages the hierarchical structure of integrated transmission–distribution (ITD) systems and casts coordination as a non-iterative\, two-layer optimisation scheme. By communicating aggregated distribution-level flexibility to the transmission layer\, the method eliminates the need for detailed distribution-network models in system-level coordination. Simulations under severe weather conditions in Germany demonstrate robustness to prediction errors and underscore the scalability and privacy-preserving properties of the proposed strategy. \nSpeaker\nDr. Xinliang DAI\nPostdoctoral Research Associate\,\nPrinceton University \nSpeaker’s Biography\nDr. Xinliang DAI received the B.Sc. degree from Jilin University\, China\, and the M.Sc. and Ph.D. degrees from the Karlsruhe Institute of Technology (KIT)\, Germany.

SUMMARY:RPG Seminar – New Paradigm for Universal Graph Prompt Tuning
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/92120929746?pwd=aL2f7KSR1uAb9rKfYOyaxpOKa9SBQL.1 \nAbstract\nWe strengthen the theoretical foundation of universal graph prompt tuning by introducing stricter constraints\, demonstrating that adding prompts to all nodes is a necessary condition for achieving the universality of graph prompts. To this end\, we propose a novel model and paradigm\, Learning and Editing Universal GrAph Prompt Tuning (LEAP)\, which preserves the theoretical foundation of universal graph prompt tuning while pursuing more ideal prompts. Specifically\, we first build the basic universal graph prompts to preserve the theoretical foundation and then employ actor-critic reinforcement learning to select nodes and edit prompts. Extensive experiments on graph- and node-level tasks across various pre-training strategies in both full-shot and few-shot scenarios show that LEAP consistently outperforms fine-tuning and other prompt-based approaches. \nSpeaker\nMr. Jinfeng Xu\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nJinfeng Xu is a Ph.D. candidate in the Department of Electrical and Electronic Engineering at The University of Hong Kong\, under the supervision of Prof. Edith C.

SUMMARY:RPG Seminar – Category Extrapolation for Long-Tail Learning
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/98761635562?pwd=7QQk1kgMNRmNcaNcVr3bsVi0A2LbZs.1#success \nAbstract\nThis paper tackles long-tailed learning where tail classes suffer from poor feature generalization due to limited sample diversity. It makes a key observation—finer-grained datasets are less harmed by class imbalance—and supports it with quantitative and qualitative evidence showing that increasing granularity improves tail-category feature generalization. Motivated by this\, the authors propose Category Extrapolation: they augment the dataset with open-set\, fine-grained auxiliary classes related to existing categories to strengthen representation learning for both head and tail classes. To automate auxiliary data collection\, they use LLMs as a knowledge base to discover related categories and web crawling to retrieve images. To prevent auxiliary classes from dominating training\, they introduce a neighbor-silencing loss that keeps the model focused on discriminating target classes; at inference time\, auxiliary classifier weights are masked out\, using only the target classes. \nSpeaker\nMr. Shizhen Zhao\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nShizhen Zhao is a PhD student in the Department of Electrical and Electronic Engineering at The University of Hong Kong (HKU).

SUMMARY:Seminar on AI Methods for Learning Quantum Systems
DESCRIPTION:Abstract\nAs quantum technologies redefine the landscape of modern electronics and communication networks\, the efficient characterisation and monitoring of complex quantum systems have become essential. In this talk\, I will present AI-driven methods to address the challenges in quantum state learning and property characterisation. First\, I will introduce the Generative Query Network for Quantum (GQNQ)\, which constructs succinct\, data-driven representations from measurement data to accurately predict unseen quantum statistics across diverse quantum systems. I will then discuss a multi-task neural network framework that extracts intricate global properties solely from short-range measurement statistics. Crucially\, our findings demonstrate powerful transfer-learning capabilities\, allowing models trained on small-scale\, classically tractable systems to generalise to much larger quantum systems. These approaches provide a scalable and universal toolkit for optimising next-generation quantum-enhanced electronic and networking systems. \nSpeaker\nDr. Amy Yuexuan WANG \nSpeaker’s Biography\nDr. Amy Yuexuan WANG obtained her Ph.D. from Zhejiang University in 2003.

SUMMARY:RPG Seminar – A Hierarchical Predictive Control Approach for Wireless Electric Vehicle Energy Network with Integrated Microgrids Incorporating Degradation Costs
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/2597624634?omn=91226274349 \nAbstract\nIntegrating the wireless electric vehicle energy network with microgrids benefits vehicle owners and grid operators. Yet\, economical and reliable operations for such combinations under renewable energy uncertainties remain examined. To address this\, achieving cost-effective and reliable performance\, a novel hierarchical predictive control approach is utilized. Its core innovation schedules optimal power dispatches for integrated microgrids using different time frames with upper-level control minimizing energy costs and battery energy storage systems’ degradation costs\, whereas lower-level control additionally lowers degradation costs. Moreover\, the approach inherently enhances system reliability by minimizing power fluctuations using control references from upper-level control and state variables feedback from lower-level control under renewable energy uncertainties. The unique cross-time-frame integration of this approach enables modeling and incorporating degradation costs to adapt costs associated with longer time frames into optimal power dispatches in shorter time frames\, reflecting the unique features of hybrid energy storage systems. Comparative studies reveal that various energy storage systems can be employed at different hierarchical control levels for tailored power distribution objectives. Effectiveness of the utilized approach is confirmed by comparing it with control benchmarks through its reduction of energy costs\, degradation costs\, and expected energy not served. \n  \nSpeaker\nMr. Ye Duan\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nYe DUAN received the B.Eng. degree in mechanical engineering and automation from Chongqing University\, Chongqing\, China\, and an M.Sc. degree in mechanical engineering and applied mechanics from The University of Pennsylvania\, Philadelphia\, USA\, in 2020 and 2022\, respectively.

SUMMARY:Seminar on Cross-Species Functional MRI (fMRI) Investigations of Reinforcement Learning
DESCRIPTION:Abstract\nReinforcement learning in humans depends on distributed neural circuits for value updating and behavioural adaptation. Cross-species comparisons\, particularly with macaques\, greatly facilitate our understanding of these mechanisms in humans by revealing conserved and evolved elements\, but they crucially depend on precise anatomical alignment to identify homologous regions and interpret functional parallels or divergences across species. \nIn this talk\, I will synthesise recent cross-species fMRI evidence on prefrontal contributions to reinforcement learning. I will first outline key methods for anatomical comparison that enable functional inferences across species despite marked differences in brain morphologies. I will then present findings from reversal learning tasks in humans and macaques\, demonstrating conserved orbitofrontal cortex signals that support rapid value updating in response to changing reward contingencies. Next\, I will discuss anterior cingulate cortex (ACC) activations in both species\, which play a key role in enacting adaptive changes. Finally\, I will highlight the anatomical uniqueness of the human frontopolar cortex (FPC)\, particularly its lateral subdivision\, which lacks a clear homolog in macaques and shows emerging functional importance in our recent findings for handling higher-dimensional aspects of reinforcement learning. \nSpeaker\nProf. Bolton KH CHAU\nDepartment of Rehabilitation Sciences\,\nThe Hong Kong Polytechnic University \nSpeaker’s Biography\nProf. Bolton KH CHAU is an Associate Professor in the Department of Rehabilitation Sciences and Associate Director of the Mental Health Research Centre at The Hong Kong Polytechnic University. He received my DPhil from the University of Oxford and was APS Rising Star by the Association for Psychological Science. His research interests lie in decision neuroscience\, with a particular focus on how the brain integrates information and sometimes arrives at irrational or biased choices. He adopts a multidisciplinary approach\, combining computational modelling\, behavioural experiments\, brain imaging\, and brain stimulation to investigate the mechanisms underlying decision-making in both simple and complex contexts. Recently\, he has developed a keen interest in the frontopolar cortex\, a region uniquely expanded in the human brain\, and its role in supporting complex decision-making.

SUMMARY:Seminar on Integration of Renewable Energy for Power Restoration: Real-time Digital Simulation Approach
DESCRIPTION:Abstract\nThe drive toward aggressive decarbonization goals is rapidly transforming the power grid\, highlighted by an increase in renewable energy production. This expansion relies heavily on Distributed Energy Resources (DERs)\, yet operators face challenges due to the lack of transparency in DER operations. This opacity poses significant risks to grid stability as the growing number of DERs could exceed the capacity of the current power network. In response\, the emergence of Digital Twins (DT) technology provides a potential solution by creating virtual replicas of the physical grid infrastructure\, which require minimal data transmission. DT technology overcomes the obstacles of real-time data flow and enhances system transparency. To encourage the wider application of DT in the industry\, it is crucial to develop and test its applications through practical experiments. For this purpose\, Power Hardware-in-the-Loop (PHIL) experiments are used to compare the effectiveness of real power components with DT models. These experiments connect Grid-forming Inverter (GFMI) to a Real-time Digital Simulator (RTDS) for PHIL and DT testing\, enabling detailed analysis of photovoltaic inverter behaviour. \nThis research presents a platform specifically built for immediate simulation suited to DT and PHIL methods. It is designed to prototype\, demonstrate\, and assess GFMIs under various critical scenarios for power restoration. By incorporating the Perez Model into the DT model through simulation exchange\, the accuracy in comparison with the traditional PHIL model is enhanced. Thus\, the entire restoration process can be thoroughly represented and analysed. All in all\, this paper introduces a novel approach to integrating renewable energy resources using PHIL-based digital twins technology to enhance power restoration stability. \nSpeaker\nDr. Jason Man Hin CHOW\nLecturer at Vocational Training Council (VTC) \nSpeaker’s Biography\nDr. Jason Man Hin CHOW obtained a BEng from the University of Sheffield and an MSc and a PhD from The University of Hong Kong\, all in Electrical and Electronic Engineering.

SUMMARY:RPG Seminar – Synthetic Aperture for High Spatial Resolution Acoustoelectric Imaging
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/97208194193 \nAbstract\nAcoustoelectric imaging (AEI) refers to the mapping of electric fields in electrolyte and tissue media by measuring the acoustoelectric (AE) effect. It shows promise for non-invasive electrophysiological mapping down to the resolution of diagnostic ultrasound imaging. AE signals are typically induced by applying focused ultrasound (FUS) waves\, which sift out the electric signals at a defined focal spot. However\, the spatial resolution of FUS-AEI is limited by the finite focal extent. To achieve improved AEI spatial resolution across the full imaging depth\, we propose to perform AEI by adopting a Synthetic Aperture (SA) approach. SA-AEI images were reconstructed through pixel-oriented delay-and-sum of the unfocused AE signals. Experiments were done on an NaCl volume and an ex vivo lobster nerve. Overall\, SA-AEI exhibited superior lateral resolution compared to FUS-AEI\, particularly for electric targets outside the focal zone of FUS-AEI. Due to inherently lower SNR of the SA approach\, we further proposed coherence-based beamforming to enhance the image quality of SA-AEI images. We envision that proposed SA-AEI would be a useful strategy for AEI\, when spatial resolution is the top imaging performance criterion and prior locations of bioelectric sources are unknown. \nSpeaker\nMr. Wei Yi Oon\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nWei Yi OON received his BEng in Medical Engineering from The University of Hong Kong in 2021.

SUMMARY:RPG Seminar – LLMs for Social Good: Addressing Data Scarcity and Opacity for Alzheimer’s Diagnosis and Prognosis
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/94842355191?pwd=02bHCUfep3119O1jbeDHbnZNKaKUJ8.1 \nAbstract\nEarly detection of Alzheimer’s Disease (AD) through non-invasive speech analysis offers a highly promising diagnostic avenue. However\, the development of robust computational models is severely hindered by the fundamental imperfections of real-world clinical data. Spontaneous patient speech is often noisy and highly variable\, while longitudinal clinical records suffer from severe data scarcity\, temporal sparsity\, and missing values. Consequently\, traditional deep learning models act as opaque “black boxes\,” and this inherent opacity undermines the clinical trust required for real-world deployment. Furthermore\, while Large Language Models (LLMs) show revolutionary potential\, they too struggle to robustly model individualized disease progression from sparse data without specialized architectural integration. This leads to the central research question: How can an LLM-driven framework be systematically designed to extract clinically meaningful features and synthesize high-fidelity multi-modal data\, thereby overcoming the intertwined limitations of data incompleteness and black-box opacity? \nTo address this\, this seminar proposes an LLM-driven spatio-temporal multi-modal framework. The overarching objective is to develop theoretically grounded methodologies that leverage LLMs to robustly distill raw patient speech into structured Cognitive-Linguistic (CL) atoms and interpretable linguistic markers. Concurrently\, the framework integrates qualitative medical knowledge and synthesizes rich\, realistic training samples to effectively enrich decision boundaries in data-deficient environments. This research significantly advances AI for Social Good by providing a scalable\, low-cost methodology for early dementia screening that reduces the reliance on invasive and expensive traditional diagnostics. \nSpeaker\nMr. Tingyu MO\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nMr. Tingyu MO is a Ph.D. candidate with the Advanced Well-being and Society Research Platform (AI-WiSe) at The University of Hong Kong\, under the supervision of Prof. Victor O.K. Li\, Prof. Jacqueline C.K. Lam\, and Prof. Yunhe Hou. He received his B.S. degree in Intelligence Science and Technology from the University of Science and Technology Beijing in 2021\, and his M.Eng. degree in Electronic and Information Engineering from Beihang University. His research interests include AI for Social Good\, with a specific focus on Alzheimer’s diagnosis and prognosis. \nOrganiser\nProf. Victor O.K Li\, Prof. Jacqueline C.K Lam\, Prof. Yunhe Hou\nDepartment of Electrical and Computer Engineering\, The University of Hong Kong \nAll are welcome.

SUMMARY:RPG Seminar – Scaling Up Spatial Awareness: High-Fidelity Data Synthesis for 3D Scene Understanding
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/91627715757?pwd=ByKZvbK3QYx8VSWXVoNGBsZXTpFEz3.1 \nAbstract\nSpatial understanding constitutes a fundamental pillar of human-level intelligence\, yet its advancement is currently bottlenecked by the scarcity of diverse\, high-fidelity 3D data. Existing research predominantly relies on domain-specific or manually annotated datasets\, creating a critical void: the absence of a principled\, scalable engine capable of synthesizing high-quality spatial data at scale. To address this\, we elucidate the core design principles for robust spatial data generation and introduce OpenSpatial—an open-source engine engineered for high fidelity\, massive scalability\, and broad task diversity. OpenSpatial adopts 3D bounding boxes as the foundational primitive to architect a comprehensive data hierarchy across five essential dimensions: Spatial Measurement\, Spatial Relationship\, Camera Perception\, Multi-view Consistency\, and Scene-Aware Reasoning. Leveraging this infrastructure\, we curate OpenSpatial-3M\, a large-scale dataset that enables models to transition from simple recognition to sophisticated spatial intelligence. Extensive evaluations demonstrate that models trained on our synthesized data achieve state-of-the-art performance across a wide spectrum of benchmarks\, showing substantial and consistent improvements over existing baselines. Furthermore\, we provide a systematic analysis of how synthesized data attributes influence the emergence of spatial perception in vision-language models.

SUMMARY:RPG Seminar – Broadband Mamyshev Oscillator at 1.7 μm for Multicolor Three-photon Fluorescence Microscopy
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/95690107722?pwd=KARbsSPDxqYtCaSbRQ0AbxNFmlyBl2.1 \nAbstract\nThree-photon fluorescence (3PF) microscopy enables high-contrast deep-tissue imaging with cellular resolution\, especially in 1.7 μm wavelength range\, yet its widespread adoption has been hindered by the lack of compact\, tunable\, and high-power femtosecond laser sources. Here\, we demonstrate a broadband tunable ultrafast Mamyshev oscillator operating in the 1.7 μm wavelength region\, specifically designed for multicolor 3PF microscopy. The all-fiber ring cavity\, incorporating two arms with tunable grating-based filters\, generates stable ultrashort pulses with flexibly tunable central wavelength from 1730 nm to 1810 nm and adjustable bandwidth up to 140 nm at 10 dB. The oscillator at 7.14-MHz repetition rate are amplified using a chirped pulse amplification (CPA) system to achieve 80-nJ pulses with a slope efficiency of 46.2%\, and finally compressed to 65 fs. We showcase the versatility of this laser source through various imaging modalities. High-contrast\, label-free third-harmonic generation (THG) images of diverse biological samples are presented. Deep-tissue vasculature 3PF images in an ex vivo mouse brain down to a depth of 1 mm are visualized. Crucially\, we achieve multicolor 3PF imaging with a single excitation wavelength for various co-labeled mouse brain samples\, visualizing the interaction between neurons and plaques with distinct morphologies in an Alzheimer’s disease mouse model. This compact\, tunable\, and high-power 1.7 μm ultrafast fiber laser establishes a powerful tool for advanced biomedical imaging\, particularly for deep tissue and multiplexed studies of neurodegenerative diseases. \nSpeaker\nMiss Xiaoxiao Wen\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nXiaoxiao Wen received her bachelor’s degree and the master’s degree from the South China University of Technology (SCUT) in 2019 and 2022\, specializing in ultrafast laser dynamics measurement. She is currently a PhD candidate at the Department of Electrical and Electronic Engineering\, the University of Hong Kong\, under the supervision of Prof. Kenneth Kin-Yip Wong.

SUMMARY:Seminar on Exploring the Feasible Net-Zero Transition Pathway in China
DESCRIPTION:Abstract\nNet-zero energy transition is projected to accelerate the replacement of fossil fuels with renewables\, leaving system flexibility resources increasingly scarce. Here\, we present a sub-annual energy-environment-economy model with endogenous hourly energy demand profiles and power balance dynamics\, including power dispatch\, storage operations and demand-side response that co-optimises supply- and demand-side flexibility\, to map feasible transition pathways for China. The results show that compared with coarser timeslice representative of common modelling practice\, sub-annual representation tightening flexibility needs with a high variable renewable energy and high electrification energy system. Accounting for temporal variability in supply and demand\, the cost-optimal solution exhibits marginal abatement costs that are over 9% higher\, but incorporating demand-side flexibility measures can mitigate cost growth and delineate least-regret portfolios for reliable\, affordable decarbonization. Incentives for demand-side response\, such as load time-shifting and vehicle-to-grid can reduce investment in pumped hydro by 23% and yield more than a threefold cost-benefit ratio. The study highlights enhanced modelling of temporal dynamics within future energy model development and incentive-compatible market mechanism design for dispatchable resource development. \nSpeaker\nProf. Shu ZHANG\nAssistant Professor\,\nInstitute of Energy\, Environment and Economy\,\nTsinghua University \nSpeaker’s Biography\nProf. Shu ZHANG is an Assistant Professor at the Institute of Energy\, Environment and Economy\, Tsinghua University.

SUMMARY:Seminar on Can Industrial Overcapacity Enable Seasonal Flexibility in Electricity Use?
DESCRIPTION:Abstract\nIn many countries\, declining demand in energy-intensive industries such as cement\, steel\, and aluminum is leading to industrial overcapacity. Although industrial overcapacity is traditionally envisioned as problematic and resource-wasteful\, it could unlock energy-intensive industries’ flexibility in electricity use. Here\, using China’s aluminum smelting industry as a case study\, we evaluate the system-level cost-benefit of retaining energy-intensive industries overcapacity for flexible electricity use in decarbonised energy systems. We find that overcapacity can enable aluminum smelters to adopt a seasonal operation paradigm\, ceasing production during winter load peaks that are exacerbated by heating electrification and renewable seasonality. This seasonal operation paradigm could reduce the investment and operational costs of China’s decarbonised electricity system by 23-32 billion CNY/year (11-15% of the aluminum smelting industry’s product value)\, sufficient to offset the increased smelter maintenance and product storage costs associated with overcapacity. It may also provide an opportunity for seasonally complementary labour deployment across the aluminum smelting and thermal power generation sectors\, offering a potential pathway for mitigating socio-economic disruptions caused by industrial restructuring and energy decarbonization. \nSpeaker\nMr. Ruike LYU\n5th year PhD.

SUMMARY:RPG Seminar – Efficient AI for Neural Signal Decoding in Healthcare Applications
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/93628966280 \nAbstract\nRecent advances in artificial intelligence have brought new momentum to healthcare driven by neural signal decoding. This seminar presents three lines of our research on AI-based neural signal analysis across diverse application domains\, including wearable EEG-based epileptic seizure detection\, emotion recognition in SSVEP-based brain–computer interfaces (BCIs)\, and multimodal neuroimaging-based tinnitus diagnosis. First\, for real-time epileptic seizure detection on resource-constrained wearable devices\, we propose a multi-scale LBP-based hyperdimensional computing framework that captures seizure-related temporal dynamics with a compact model size\, strong few-shot learning capability\, and improved interpretability. Second\, to enhance emotion-aware interaction in SSVEP-based BCIs\, we develop a valence-arousal disentangled representation learning method that separates core emotional factors\, extracts global affective features\, and improves cross-subject generalization. Third\, for objective tinnitus diagnosis\, we introduce TinnitusLLM\, a multimodal large language model that integrates EEG and fMRI through neuro-inspired positional encoding\, multimodal autoregressive pretraining\, and subject-invariant cross-modal fine-tuning. Across these studies\, our common goal is to build efficient\, interpretable\, and clinically meaningful learning frameworks for robust neural decoding in real-world healthcare and human–machine interaction scenarios. \nSpeaker\nMr Yipeng Du\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nYipeng Du is currently pursuing the Ph.D. degree in the Department of Electrical and Electronic Engineering at The University of Hong Kong.

SUMMARY:RPG Seminar – Doppler LiDAR Motion Planning for Highly-Dynamic Environments
DESCRIPTION:Zoom Link:\nhttps://us05web.zoom.us/j/83514440427?pwd=4Lao2gGnkpLnw510JJXc0mXIaXCmJ5.1 \nAbstract\nExisting motion planning methods often struggle with rapid-motion obstacles due to an insufficient understanding of environmental changes. To address this limitation\, we propose integrating motion planners with Doppler LiDARs which provide not only ranging measurements but also instantaneous point velocities. However\, this integration is nontrivial due to the dual requirements of high accuracy and high frequency. To this end\, we introduce Doppler Planning Network (DPNet)\, which tracks and reacts to rapid obstacles using Doppler model-based learning. Particularly\, we first propose a Doppler Kalman neural network (D-KalmanNet) to track the future states of obstacles under partially observable Gaussian state space model. We then leverage the estimated motions to construct a Doppler-tuned model predictive control (DT-MPC) framework for ego-motion planning\, enabling runtime auto-tuning of the controller parameters. These two model-based learners allow DPNet to maintain lightweight while learning fast environmental changes using minimum data\, and achieve both high frequency and high accuracy in tracking and planning. Experiments on both high-fidelity simulator and real-world datasets demonstrate the superiority of DPNet over extensive benchmark schemes. \nSpeaker\nMr Wei Zuo\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nWei Zuo received his bachelor’s degree from Beijing Institute of Technology (BIT) in 2024\, majored in Automation.

SUMMARY:RPG Seminar – Evolving LEO Satellite Constellations into Multi-Service Platforms
DESCRIPTION:Abstract\nLow Earth orbit (LEO) satellite constellations offer global communication capabilities\, yet fundamental system challenges restrict their full utility. Specifically\, under increasing user demands\, these networks face difficulties in optimizing internal traffic distribution and efficiently delivering advanced content services. Furthermore\, seamlessly integrating space-based infrastructure with terrestrial systems to ensure resilient operations remains an unresolved issue. Solving these challenges is required to transition LEO constellations from basic connectivity relays into integrated service platforms. \nThis presentation explores optimization and extension strategies for evolving LEO satellite networks. Focusing first on the internal constellation network\, we begin with Matchmaker to address traffic distribution challenges through effective load balancing to enhance network performance. To ensure quality of service (QoS) in large-scale constellations\, an efficient heuristic algorithm that minimizes maximum satellite utilization and handovers is proposed. With this optimized network foundation\, we elevate the constellation’s capabilities through SpaceCache+\, transforming it into a space-based content delivery network (CDN). SpaceCache+ deploys cache-equipped satellites and optimizes cache replacement by managing dynamic coverage and regional preferences through zero-shot meta-learning and spatial-temporal mixing. Having expanded the constellation’s internal capacity\, we finally project its utility outward to assist terrestrial infrastructure via SpaceHelper. This work integrates satellite resources with terrestrial software-defined wide area networks (SD-WANs) to construct a resilient out-of-band control plane\, ensuring rapid reconnection during terrestrial link failures. Together\, these works illustrate a continuous system evolution\, advancing LEO networks from basic Internet access to comprehensive space-based multi-service platforms. \nSpeaker\nMr Dou Songshi\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nSongshi Dou received B.E. degree from North China Electric Power University\, Beijing\, China\, in 2019\, and M.E. degree from Beijing Institute of Technology\, Beijing\, China\, in 2022.

SUMMARY:Seminar on Machine Learning for Integrated Sensing and Communication
DESCRIPTION:Abstract\nIntegrated sensing and communication (ISAC) is a key technology for the sixth-generation (6G) wireless networks\, where the same spectral and hardware resources are used for both communication and environmental sensing. Many optimization problems in ISAC require accurate sensing and communication channel models\, which are often difficult to obtain. Machine learning (ML) is a powerful tool for solving ISAC problems by enabling data-driven solutions that can bypass the reliance on explicit models. This talk will explore how ML techniques can improve ISAC performance beyond traditional optimisation approaches. Two case studies will be discussed: sensing-assisted predictive beamforming and cooperative sensing through ML. These examples will demonstrate the potential of ML to enable end-to-end signal processing for ISAC in 6G wireless networks. \nSpeaker\nProf. Vincent WONG\nProfessor\,\nDepartment of Electrical and Computer Engineering\,\nUniversity of British Columbia\, Vancouver\, Canada \nSpeaker’s Biography\nVincent WONG is a Professor in the Department of Electrical and Computer Engineering at the University of British Columbia\, Vancouver\, Canada.

SUMMARY:RPG Seminar – System Design for Wide-field Miniature Fluorescence Microscope
DESCRIPTION:Zoom Link:\nhttps://us05web.zoom.us/j/89432980495?pwd=LSDClCuSVwd9fL5oZaI532byF2aC1a.1 \nAbstract\nMiniature fluorescence microscope\, or miniscope\, is a compact fluorescence imaging system that integrates the excitation source\, optical filters\, imaging optics\, and image sensor into a small platform.  Among various technical approaches\, one-photon widefield miniscopes are especially attractive because of their relatively simple architecture\, strong engineering feasibility\, and compatibility with two-dimensional superficial imaging tasks. However\, existing miniscope systems still face important challenges\, particularly in balancing a large field of view with high spatial resolution\, maintaining image quality across the full field\, and achieving compact system integration. \nThis seminar focuses on the optical design of one-photon widefield miniature fluorescence microscopes for two-dimensional superficial imaging\, with the main emphasis placed on a single-channel system. The study investigates the key design considerations of excitation and emission light separation\, imaging optics configuration\, aberration control\, and system compactness\, aiming to achieve high-resolution fluorescence imaging over a relatively large field of view within a miniature platform. On this basis\, scalable multi-channel architectures are briefly considered as extensions to examine the feasibility of multi-channel integration in miniature fluorescence imaging systems. The work provides a system-oriented design framework for one-photon widefield miniscopes and highlights practical strategies for improving imaging performance\, structural integration\, and architectural scalability. \nSpeaker\nMr Wentao Ye\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nWentao Ye is an MPhil student in the Department of Electrical and Computer Engineering at The University of Hong Kong\, supervised by Prof. Feifei Wang.

SUMMARY:RPG Seminar – A General Deep Learning Framework for Wireless Resource Allocation under Discrete Constraints
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/99219579381?pwd=IjEXStaAdwdBhtSyoZ0aYbLavr0zhX.1 \nAbstract\nDeep learning (DL)-based methods have achieved remarkable success in continuous wireless resource allocation\, yet its application to problems involving discrete variables remains hindered by the zero-gradient issue\, complex constraint enforcement\, and the lack of non-same-parameter-same-decision (non-SPSD) guarantees. To address these challenges\, this seminar presents a novel DL framework that leverages probabilistic modeling of the discrete support set to enable efficient\, end-to-end optimization. The speaker will further demonstrate the efficacy of this framework through two challenging mixed-discrete wireless resource allocation applications: (a) joint user association and beamforming in cell-free systems\, and (b) joint antenna positioning and beamforming in movable antenna-aided systems. The results demonstrate the superior performance of the proposed framework compared to the  state-of-the-art optimization algorithms and learning-based methods. \nSpeaker\nMr. Yikun WANG\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nYikun Wang received the B.E. degree in Communication Engineering from Beihang University.
