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:Seminar on Mechanism Design for the Evolving Landscape of Sustainable Power Systems
DESCRIPTION:Abstract\nModern power systems are undergoing rapid transformation driven by the integration of emerging technologies\, diverse participants\, and innovative business models. These changes offer unprecedented opportunities to enhance system reliability within existing infrastructure\, reduce electricity costs\, and accelerate renewable energy adoption. However\, they also introduce complex market interactions that require rigorous analytical frameworks to ensure efficiency\, fairness\, and sustainability. \nIn this talk\, the speaker will discuss our recent research on leveraging game-theoretic modelling to analyse and design mechanisms for these evolving power systems. His studies examine the impacts of coincident peak-shaving programs and energy storage participation in wholesale electricity markets through competitive equilibrium models. He also explores optimal pricing strategies for voluntary renewable energy contracts that promote large-scale renewable deployment. Together\, these results underscore the importance of a principled understanding of emerging market structures and provide guidance for designing future policies that balance economic efficiency\, reliability\, and sustainability in power systems. \nSpeaker\nProf. Bolun XU\nAssistant Professor\,\nColumbia University \nSpeaker’s Biography\nProf. Bolun XU is an Assistant Professor in Earth and Environmental Engineering at Columbia University\, with an affiliated appointment in Electrical Engineering.

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.

SUMMARY:RPG Seminar – Fast customization of color centers in single nanodiamonds and its applications
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/91528535994?pwd=pagmffbltruagBNPmFkEWo5sxaFJrN.1 \nAbstract\nDeterministic control of nitrogen–vacancy (NV) centers in nanodiamonds (NDs) is critical for emerging applications in quantum photonics and high-density optical data storage. Conventional approaches based on random irradiation and thermal annealing often lead to nondeterministic NV formation and lattice damage\, making it difficult to precisely control the optical properties of the color centers and resulting in low fabrication yields. In this seminar\, we present a rapid and targeted approach for customizing NV centers in pre-selected single nanodiamonds using a standard transmission electron microscope (TEM). A brief 1-second electron beam exposure enables NV formation without post-annealing while minimizing lattice damage. The resulting nanodiamonds exhibit stable optical and spin properties. Furthermore\, controlled TEM exposure can quench NV photoluminescence within tens of seconds\, enabling a fast write–erase process. Leveraging this capability\, we demonstrate a flexible nanodiamond-based optical data storage platform. This accessible and highly targeted method provides a powerful route for on-demand NV center engineering and opens new opportunities for quantum technologies and nanoscale photonic data storage. \nSpeaker\nMiss Jiaqi Li\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nJiaqi Li received her BEng degree in Physics from South China Normal University in 2022.

SUMMARY:RPG Seminar – From 2D to 3D: Enhancing Ultrasound Resolution through Null Subtraction Beamforming
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/99658715385?pwd=NaDaq5EIkqa3RYU4pDDYxbz5stbh45.1 \nAbstract\nHigh-frame-rate ultrasound imaging is a cornerstone of modern medical diagnostics and structural monitoring\, yet it remains bound by the classical trade-off between spatial resolution and acquisition speed. While conventional delay-and-sum (DAS) beamforming is the industry standard\, its resolution is fundamentally limited by the transducer’s diffraction pattern. This seminar introduces Null Subtraction Imaging (NSI)\, a nonlinear beamforming strategy designed to surpass these diffraction limits. We begin by establishing the principles of 2D NSI\, where thee apodization windows are used to synthesize a “null” beampattern that effectively sharpens the mainlobe. Building on this foundation\, the talk focuses on the extension of this technique into 3D NSI. We discuss the unique challenges of volumetric imaging\, including the complexity of 2D aperture design and the computational demands of matrix arrays. By leveraging specialized apodization masks and hardware-efficient sampling strategies\, 3D NSI achieves improvements in both azimuthal and elevational resolution\, as well as contrast ratio\, over DAS. The presentation will detail the theoretical framework\, simulation results\, and experimental validation\, demonstrating a scalable path toward high-resolution\, real-time 4D ultrasound imaging. \nSpeaker\nMr Bingze Dai\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nBingze Dai received his M.S. in Electrical and Computer Engineering at University of Illinois\, Urbana-Champaign in 2023\, and B.S. in Electronic and Information Engineering at Beijing Institute of Technology in 2019.

SUMMARY:RPG Seminar – Multi-Dimensional Nano-Printing of Colloidal Quantum Dots for Infrared Optoelectronics
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/92581464035?pwd=APBvw8rHe96aZfdqA9bhiKatjwmjXe.1 \nAbstract\nAdditive manufacturing enables the bottom-up fabrication of tailored and functional optoelectronic devices. However\, realizing printed (opto)electronics with micro- and nanoscale features and multi-dimensional structures remains challenging.\nHere\, we developed electrohydrodynamic (EHD) printing as the platform for the in-situ deposition of sub-micron-resolution colloidal quantum dot (QD) inks from quasi-2D monolayers to 2D lines and films\, and to quasi-3D walls.\nBy optimizing printing parameters\, such as the amplitude and offset of the applied waveform\, as well as the printing speed\, uniform and continuous 2D QD lines with linewidths as small as 300 nm can be obtained without post-processing.\nThen we performed solvent engineering on the QD ink\, enabling printed QDs to form closely packed quasi-2D monolayers and even short-range-ordered hexagonal superlattices. Besides\, by stacking multiple printed 2D lines\, our printer enables the fabrication of quasi-3D QD walls with aspect ratios ranging from 0.25 to 2.\nFinally\, we demonstrate QD patterning with a resolution exceeding 10\,000 dots per inch (dpi) and tunable thickness. The multi-dimensional EHD-printed QD arrays can serve as color-conversion layers for micro-LEDs (thicknesses over 1 μm) and also hold promise as a new solution for the patterning of QD-LED emissive layers (thicknesses less than 100 nm). \nSpeaker\nMr. Zeqi WANG\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nZeqi Wang received his BEng in Optoelectronic Information Science and Engineering from Southern University of Science and Technology in 2024.

SUMMARY:RPG Seminar – A BO-based Method for Parameter Tuning in Voltage Controlled DERs to Improve Flexibility Area at TSO-DSO Interface
DESCRIPTION:Zoom Link:\nhttps://us05web.zoom.us/j/82211644170?pwd=MUs6qBHh0EZskKbZOsacWOHAGHK4rQ.1 \nAbstract\nThe rapid proliferation of aggregated flexible resources in active distribution systems (ADSs) calls for accurate estimation of the flexibility area (FA) at the transmission system operator–distribution system operator (TSO–DSO) interface to improve operational coordination. Meanwhile\, voltage control plays a critical role in maintaining both economic and secure grid operation. However\, the relationship between voltage control parameters and the FA metric is highly nonlinear and analytically intractable\, as inverter droop coefficients and other control parameters interact with network constraints and distributed energy resource (DER) operating conditions in a coupled manner. \nTo address this challenge\, this paper proposes a Bayesian optimization (BO)-based framework that systematically tunes voltage support parameters to maximize the FA potential. The main contributions are threefold: (1) a cross-layer optimization paradigm that links inverter-level droop control with systemlevel FA characteristics\, revealing how voltage control curves shape interface power flow dynamics; (2) a reformulated FA estimation process in which the Interval-Constrained Power Flow (ICPF) model\, embedded with droop-control operations\, is cast as a Bayesian black-box problem solved efficiently via Gaussian process surrogates with a tile-coding kernel; and (3) a composite performance index\, namely the Secure Area–Cost Flexibility (SeCoF)\, which jointly quantifies the trade-off between flexibility enhancement and operational cost. Case studies on modified IEEE 13-bus and IEEE 37-bus distribution systems demonstrate the effectiveness\, robustness\, and scalability of the proposed method in improving both technical flexibility and economic performance under realistic operational constraints. \nSpeaker\nMiss Zihui HONG\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nZihui Hong received his BEng in Electrical and Electronic Engineering from Huazhong University of Science and Technology in 2024.

SUMMARY:RPG Seminar – Toward Trustworthy Network Intrusion Detection: From Representation Learning to Multi-Agent Orchestration
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/94349548162?pwd=rk4r0ND8iT1JzXjGsg293RmHKPGrjg.1 \nAbstract\nModern network intrusion detection systems face critical challenges in open and dynamic environments\, including concept drift as threat patterns evolve\, label noise as annotations are inherently unreliable\, and limited interpretability as detection decisions are difficult to understand and trust. This seminar presents our recent progress toward a trustworthy intrusion detection paradigm. We propose a representation enhancement framework that learns drift-aware and noise-robust feature embeddings\, enabling detectors to sustain high accuracy under non-stationary and imperfectly labeled conditions. We further introduce an LLM-based hierarchical multi-agent system that brings semantic reasoning into intrusion detection\, delivering both strong detection performance and human-interpretable explanations. These works chart a path from robust representation learning to next-generation agentic inference\, advancing network intrusion detection toward greater robustness\, adaptivity\, and trustworthiness. \nSpeaker\nMr Shuo YANG\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nShuo Yang is a Ph.D. candidate in the Department of Electrical and Computer Engineering at The University of Hong Kong\, under the supervision of Prof. Edith C.

SUMMARY:RPG Seminar – Mobile Reasoning-as-a-Service via Distributed LLM Inference-Time Scaling
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/6589092185?pwd=19EpQ4AqzgRRwQzym8vF0aaKui1J2b.1 \nAbstract\nInference-time scaling has emerged as an effective approach for enhancing the capabilities of Large Language Models (LLMs)\, addressing the growing demand for stronger reasoning without increasing model size. This novel form of LLM scaling comprises two representative approaches: explicit reasoning\, which generates intermediate chain-of-thought tokens during an explicit thinking phase\, and implicit reasoning\, which iteratively updates hidden states in the latent space without producing explicit outputs. Despite their effectiveness\, both paradigms incur substantial computational and memory overhead\, raising challenges for deployment on resource-constrained edge devices. To address these issues\, we propose a Mobile Reasoning-as-a-Service framework that treats reasoning as a computational service accessible to edge devices over wireless networks. Focusing on implicit reasoning\, we leverage its recursive structure to partition hidden-state updates between edge devices and servers\, enabling cooperative inference that allows devices to access additional cloud computation on demand. To handle dynamic wireless conditions and optimize long-term performance\, we formulate a joint computation and communication scheduling problem and solve it using a semantic Mixture-of-Experts (MoE)-based Soft Actor-Critic (SAC) algorithm to address heterogeneity in wireless conditions and task demands. Ultimately\, this work validates distributed inference-time scaling through semantic-aware collaborative reasoning services\, offering a scalable and efficient paradigm for deploying advanced LLM reasoning at the mobile edge \nSpeaker\nMr. Guanchen LIU\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nGuanchen Liu received his B.S. degree from the Harbin Institute of Technology.
