SUMMARY:Opportunities from Quantum Computing for Net-Zero Power System Optimisation
DESCRIPTION:Abstract\nOptimised power system planning and operation are core to delivering a low-cost and high-reliability transition path to net-zero carbon emissions. However\, power system optimisation problems are now posing challenges for even the largest exa-scale supercomputers. A new avenue for progress has been opened by recent breakthroughs in quantum computing. Quantum computing offers a fundamentally new computational infrastructure with different capabilities and trade-offs\, and is reaching a level of maturity where\, for the first time\, a practical advantage over classical computing is available for specific applications. The talk will present emerging opportunities where quantum computing can offer value for power system optimisation\, including combinatorial\, convex and machine learning-based optimisation problems. The talk will also discuss challenges for implementation and scale-up\, and outline promising directions for future research. \nSpeaker\nProfessor Thomas MORSTYN\nAssociate Professor in Power Systems\,\nDepartment of Engineering Science\,\nUniversity of Oxford \nBiography of the Speaker\nThomas MORSTYN is an Associate Professor in Power Systems with the Department of Engineering Science\, University of Oxford and he leads the Power Systems Architecture Lab.

SUMMARY:Shant Reactive Power Compensation Technologies
DESCRIPTION:Abstract\nReactive power compensation plays a critical role in improving power quality\, enhancing voltage stability\, and optimizing the efficiency of electrical power systems. This presentation will first highlight the main applications of shunt reactive power compensators and provide an overview of key technologies\, including Static Var Compensators (SVC)\, and Static Synchronous Compensators (StatComs). Then the focus will shift to StatCom\, which is considered state-of-the-art technology with superior performance. However\, the widespread adoption of high-power StatComs is hindered by cost constraints\, partly due to the large capacitor banks required in conventional Cascaded H-Bridge (CHB) multilevel converters. The presentation will discuss research advancements to highlight\, pros and cons of operating a CHB StatCom with low capacitance values. \nSpeaker\nProf. Glen FARIVAR\nNanyang Technological University (NUT Singapore) \nBiography of the Speaker\nGlen Farivar received PhD in Electrical Engineering from the University of NSW Australia in 2016.

SUMMARY:On The Interplay of T and R in VCM-based 1T1R Structures
DESCRIPTION:Abstract\nRedox-based resistive switching random access memory (ReRAM) which is frequently discussed as a promising non-volatile memory as well as a central element in novel neuromorphic computing applications\, is typically integrated in 1-transistor-1-resistor (1T1R) structures. While the access transistor is required as a selective device and acts as an effective current compliance during SET\, it may hinder the RESET operation due to its series resistance. We showed that this may lead to a rare endurance failure. Furthermore\, the RESET speed is affected by the voltage divider of transistor and ReRAM cell\, where the initial cell resistance\, the gate voltage and the transistor geometry (i.e.\, width over length ratio w/L) are crucial. For both\, the HRS and LRS\, we demonstrate that the operation point of the 1T1R voltage divider can be shifted between the linear and the saturation regime of the transistor transfer characteristics. \nSpeaker\nDr. Stefan Wiefels\nPGI-7\, Forschungszentrum Jülich \nBiography of the Speaker\nStefan Wiefels was born in Grevenbroich\, Germany. He received the M.Sc. degree in materials science and the Ph.D. degree in electrical engineering and information technology from RWTH Aachen University\, Aachen\, Germany\, in 2016 and 2021\, respectively. His current research group is centered around the electrical characterization of memristive devices\, reaching from Redox-based resistive switches (ReRAM) to phase change memory (PCM) and from single cells (1R)\, via 1-transistor-1-resistor (1T1R) structures to arrays and circuits. A general focus lies on the automation of measurement schemes to generate significant statistics. This allows for understanding the intrinsic variability of resistive switching devices and is crucial to identify rare failure mechanisms. Further\, variability aware algorithms to program memristive devices are developed. A general target is emulating neuromorphic functionalities using external DAC and ADC before they are integrated on chip. \nOrganisers\n– Can Li\, Department of Electrical and Electronic Engineering\, The University of Hong Kong\n– Center for Advanced Semiconductor and Integrated Circuit \nAll are welcome!

SUMMARY:Quantum Technologies with Hexagonal Boron Nitride
DESCRIPTION:Abstract\nEngineering robust\, solid-state quantum systems is amongst the most pressing challenges to realise scalable quantum photonic circuitry. While several 3D systems (such as diamond or gallium arsenide) have been thoroughly studied\, solid state emitters in van der Waals (vdW) and two dimensional (2D) materials are still in their infancy. \nIn this presentation\, I will discuss the appeal of an emerging vdW crystal – hexagonal boron nitride (hBN). This unique system possesses a large bandgap of ~ 6 eV and can host single defects that can act as ultra-bright quantum light sources. In addition\, some of these defects exhibit spin dependent fluorescence that can be initialised and coherently manipulated. I will discuss in details various methodologies to engineer these defects and show their peculiar properties. Furthermore\, I will discuss how hBN crystals can be carefully sculpted into nanoscale photonic resonators to confine and guide light at the nanoscale. Taking advantage of the unique 2D nature of hBN\, I will also show promising avenues to integrate hBN emitters with silicon nitride photonic crystal cavities. \nAll in all\, hBN possesses all the vital constituents to become the leading platform for integrated quantum photonics. To this extent\, I will highlight the challenges and opportunities in engineering hBN quantum photonic devices and will frame it more broadly in the growing interest with 2D materials nanophotonics. \nSpeaker\nProf. Igor Aharonovich\nSchool of Mathematical and Physical Sciences\,\nFaculty of Science\,\nUniversity of Technology Sydney \nBiography of the Speaker\nIgor Aharonovich is an award-winning scientist working on cutting-edge research into quantum sources that are able to generate\, encode and distribute quantum information. A Professor in the School of Mathematical and Physical Sciences at UTS\, Igor investigates optically active defects in solids\, with the aim of identifying a new generation of ultra-bright solid state quantum emitters. He is a chief investigator at the ARC Centre of Excellence for Transformative Meta-Optical Materials (TMOS)\, and leads an international collaboration investigating the chemical structure of crystal imperfections\, or defects\, in the nanomaterial hexagonal boron nitride (hBN). \nIn 2016\, Igor and his team discovered the first quantum emitters in 2D materials that operate at room temperature based on defects in hBN. He has co-authored more than 200 peer-reviewed publications\, including one of the most cited reviews on diamond photonics. He has also written a road map for solid state single-photon sources. In 2019\, Igor co-founded the inaugural online photonics conference\, Photonics Online Meetup\, which attracted more than 1100 attendees from around the world\, and which was highlighted by top science outlets. The conference now runs twice a year. He has received several international awards including the Pawsey Medal (2017)\, the IEEE Photonics Young Investigator Award (2016) and in 2020 he was the recipient of the Kavli Foundation Early Career Lectureship in Materials Science from Materials Research Society. In 2021\, he became a Fellow of the Optical Society (OSA)\, and in 2024 elected as a fellow of SPIE.\nRead more about the speaker’s biography: https://profiles.uts.edu.au/Igor.Aharonovich \nOrganiser\nProf. Zhiqin Chu\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nSupported by\nTam Wing Fan Innovation Wing Two \nAll are welcome! \nDirection: https://innowings.engg.hku.hk/innowing2/visitors

SUMMARY:In-memory\, Mixed Analog-digital Architectures for Energy-efficient Computing Applications
DESCRIPTION:Abstract\nThere is simultaneously an interest for more energy-efficient hardware in challenging applications\, as well as a drive to overhaul the von Neumann architecture toward more brain-like architectures. Compute-in-Memory (CIM) is one emerging paradigm addressing key memory bottlenecks such as bandwidth limitations\, access latency\, and high data movement energy in conventional computing platforms.\nIn part one\, we use this paradigm to accelerate the solving of challenging optimization problems. We describe our in-memory\, hardware approach built around modified Hopfield neural networks to accelerate problem classes such as Boolean satisfiability (3-SAT). In an algorithm-hardware co-design process\, we have developed three different architectures steadily improving on the state-of-the-art. We discuss issues encountered in mapping native optimization problems to physical hardware\, precision demands\, and matching mixed analog-digital blocks to the algorithmic needs. Quantitative performance comparisons to competing approaches in both mature and emerging technologies will be presented.\nIn the second part of the talk\, we extend CIM beyond matrix-dominant workloads\, exploring its potential for novel and powerful models like Kolmogorov-Arnold Networks (KAN). Our new work\, called “KA-CIM\,” provides hardware acceleration for KANs. KANs offer significant parameter reduction over traditional neural networks for AI+Science applications but relies on computationally expensive non-linear functions. We present an innovative memory-centric design that enables energy-efficient and flexible computation of non-linear functions central to KAN\, while efficiently executing KAN inference.\nWe also discuss analog CIM using commodity DRAM architectures. Unlike SRAM- and emerging memory-based CIM accelerators\, DRAM-based CIM offers both high memory capacity and technological maturity\, making it an attractive candidate for large-scale AI workloads. This portion of the talk will present both the opportunities and constraints of using commodity DRAM for CIM. A novel analog CIM architecture will be presented\, which mitigates several of these constraints and demonstrates how area- and power-intensive ADCs can be efficiently integrated within an area-optimized commodity DRAM design. Furthermore\, a key feature of this architecture is its Dual-Mode functionality\, enabling it to seamlessly operate as both conventional main memory and an accelerator. \nSpeakers\nProf. John Paul Strachan\nProfessor\, RWTH Aachen University\, Aachen\, Germany\nHead\, Peter Grünberg Institute (PGI-14)\, Forschungszentrum Jülich\, Jülich\, Germany\n\nDr. Chirag Sudarshan\nPostdoctoral Researcher\nPeter Grünberg Institute (PGI-14)\, Forschungszentrum Jülich\, Jülich\, Germany \nBiography of the Speakers\nProf. John Paul Strachan directs the Peter Grünberg Institute on Neuromorphic Compute Nodes (PGI-14) at Forschungszentrum Jülich and is a Professor at RWTH Aachen.  Previously he led the Emerging Accelerators team as a Distinguished Technologist at Hewlett Packard Labs\, HPE.

SUMMARY:RPG Seminar – Personalized Video Fragment Recommendation
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/96780307210?pwd=1wIMCFlBwNOSDiVMsEFxnVgzm5kLnn.1\nMeeting ID: 967 8030 7210\nPassword: 943198 \nAbstract\nIn the current digital landscape\, capturing user attention for long video content is increasingly challenging due to diminishing attention spans. While video production is shifting towards shorter formats\, there remains significant value in leveraging the huge volume of extant long videos to meet fast-paced user consumption habits. Addressing this challenge\, our talk presents a novel framework designed to recommend specific video fragments from long videos that align with individual user profiles. Our approach is based on three key insights: the inter-fragment contextual effect\, which leverages the complex relationships among fragments within a long video; the intra-fragment contextual effect\, which models herding effects from multi-modal signals in a single video fragment; and video-level preferences\, which ensure consistency with users’ overarching interests. Extensive experiments demonstrate that our model achieves superior performance across multiple key metrics\, outperforming state-of-the-art methods. \nSpeaker\nMr. Wang Jiaqi\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nBiography of the Speaker\nJiaqi Wang received the B.E. degree in Computer Science and Technology from South China University of Technology.

SUMMARY:2D Materials for Next-Generation Electronics: From Low-Power Logic to Monolithic Memory
DESCRIPTION:Abstract\nSilicon has been the dominant material for electronic computing for decades and very likely will stay dominant for the foreseeable future. However\, it is well-known that Moore’s law that propelled Silicon into this dominant position is long dead. Therefore\, a fervent search for (i) new semiconductors that could directly replace silicon or (ii) new architectures with novel materials/devices added onto silicon or (iii) new physics/state-variables or a combination of above has been the subject of much of the electronic materials and devices research of the past 2 decades. The above problem is further complicated by the changing paradigm of computing from arithmetic centric to data centric in the age of billions of internet-connected devices and artificial intelligence as well as the ubiquity of computing in ever more challenging environments. Therefore\, there is a pressing need for complementing and supplementing Silicon to operate with greater efficiency\, speed and handle greater amounts of data. This is further necessary since a completely novel and paradigm changing computing platform (e.g. all optical computing or quantum computing) remains out of reach for now. The above is however not possible without fundamental innovation in new electronic materials and devices. Therefore\, in this talk\, I will try to make the case of how novel layered two-dimensional (2D) chalcogenide materials1 and three-dimensional (3D) nitride materials might present interesting avenues to overcome some of the limitations being faced by Silicon hardware. I will start by presenting our ongoing and recent work on integration of 2D chalcogenide semiconductors with silicon2 to realize low-power tunnelling field effect transistors. In particular I will focus on In-Se based 2D semiconductors2 for this application and extend discussion on them to phase-pure\, epitaxial thin-film growth over wafer scales\,3 at temperatures low-enough to be compatible with back end of line (BEOL) processing in Silicon fabs. I will then switch gears to discuss memory devices from 2D materials when integrated with emerging wurtzite structure ferroelectric nitride materials4 namely aluminium scandium nitride (AlScN). First\, I will present on Ferroelectric Field Effect Transistors (FE-FETs) made from 2D materials when integrated with AlScN and make the case for 2D semiconductors in this application.5-7 Finally\, I will end with showing our most recent results on scaling 2D/AlScN FE-FETs\, achieving ultra-high carrier and current densities8 in ferroelectrically gated MoS2 and also demonstrate negative-capacitance FETs9 by engineering the AlScN/dielectric/2D interface. \nSpeaker\nProf. Deep Jariwala\nAssociate Professor\nPeter and Susanne Armstrong Distinguished Scholar\nElectrical and Systems Engineering Primary\nMaterials Science and Engineering\nThe University of Pennsylvania \nBiography of the Speaker\nDeep Jariwala is an Associate Professor and the Peter & Susanne Armstrong Distinguished Scholar in the Electrical and Systems Engineering as well as Materials Science and Engineering at the University of Pennsylvania (Penn).

SUMMARY:RPG Seminar – Six Degrees of Freedom Tracking and Wireless Charging for Capsule Endoscopy
DESCRIPTION:Zoom \nLink: https://hku.zoom.us/j/95045238787?pwd=bAEbF49kv8uPbKPQG1n3B5I9bSphnT.1\nMeeting ID: 950 4523 8787\nPassword: 123456 \nAbstract\nCapsule endoscopy is an emerging technology providing a non-invasive approach to diagnose and monitor gastrointestinal diseases. However\, this technology has fundamental limitations of short-range of investigation due to limited battery capacity and uncertain position of the capsule inside the gastrointestinal tract. This research work attempts to address these two critical issues using a novel approach to seamlessly combine wireless battery charging\, and 6 degrees of freedom (6DoF) tracking of capsule endoscopy on a single apparatus. A full-scale complete prototype is presented in this paper\, wherein the receiving coil is integrated in a fully functional capsule\, and the transmitting coil is able to accommodate an adult human body. In the tracking operation\, a gradual DC magnetic field is generated in the transmitting coil. The magnetic field intensity surrounding the capsule is measured and consolidated with inertial measurement to identify the capsule’s position and orientation. In the evaluation\, the maximum mean absolute error for attitude angles and position are less than 3.80° and 2.07 mm\, respectively. A relatively uniform AC magnetic field will be generated while a low battery is detected. During wireless charging\, the capsule receives 376.08 mW of power\, resulting in an estimated charging rate of 2C for the capsule battery. \nSpeaker\nMr. ZHANG Heng\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nBiography of the Speaker\nHeng ZHANG received the B.Eng. degree in 2017\, and the M.Eng. degree in 2020\, both in Electrical Engineering and Automation\, from Taiyuan University of Technology\, Taiyuan\, Shanxi\, China.

SUMMARY:Revolutionizing Power Electronics with Heterogeneous Integration
DESCRIPTION:Abstract\nTraditional power electronic equipment has long relied on discrete active and passive components\, with performance enhancements often requiring trade-offs. Despite technological advancements\, manufacturing processes remain labor-intensive and largely unchanged for decades. \nThe advent of wide-bandgap (WBG) power semiconductor devices\, such as silicon carbide (SiC) and gallium nitride (GaN)\, has significantly reduced conduction and switching losses compared to silicon-based counterparts. However\, current design methodologies primarily follow a ‘plug-and-play’ approach\, yielding only incremental improvements in efficiency and power density without fully leveraging the transformative potential of these technologies. \nThis presentation explores the integration of matrix magnetics with WBG power devices to drive a fundamental shift in power electronics design and manufacturing through heterogeneous integration. This holistic approach enables simultaneous enhancements in efficiency\, power density\, cost\, and electromagnetic interference (EMI) performance. Additionally\, it streamlines traditionally labor-intensive manufacturing processes—particularly those involving magnetics and system assembly—through automation. \nThe discussion will feature multiple research examples demonstrating heterogeneous integration of matrix magnetics in power converters across diverse applications and power ranges. These include high-frequency power converters for artificial intelligence (AI) and high-performance computing systems\, battery chargers for electric vehicles\, and solid-state transformers for DC power distribution. \n\nSpeaker\nProf. Qiang LI\nCenter for Power Electronics Systems (CPES)\,\nVirginia Tech \nBiography of the Speaker\nQiang Li received the B.S. and M.S. degrees from Zhejiang University\, China\, in 2003 and 2006\, respectively\, and the Ph.D. degree from Virginia Tech\, Blacksburg\, VA\, in 2011. He is currently a full professor in the Center for Power Electronics Systems (CPES) at Virginia Tech. His research interests include high-frequency power conversion and control\, high-density electronics packaging and magnetic integration\, as well as power solutions for high-performance computing\, data centers\, electric vehicles\, and energy storage systems.

SUMMARY:RPG Seminar – Configuration Strategy for Inertia Response and Primary Frequency Regulation
DESCRIPTION:Zoom link: https://hku.zoom.us/j/93192694458?pwd=S4PuTAT2tuI2idxEmbPCwEA0IU0ugx.1\nMeeting ID: 931 9269 4458\nPassword: 982082 \nAbstract\nThe energy storage(ES) systems controlled by Virtual Synchronous Generation (VSG) system provide inertia\, damping\, and enhance system stability. When transient overshoot in power and energy exceed the capacity constraints of the ES systems\, the output performance for inertia response (IR) and primary frequency regulation (PFR) oscillates instantly towards instability\, leading to shutdown. To optimize the configuration of ES systems\, we establishes an energy output model that responds to the variations of grid frequency based on IR and PFR. The expressions of power and energy demands are derived from the energy output model\, relating inertia\, damping\, and primary frequency regulation coefficient. Furthermore\, the optimal configuration approaches are summarized under different damping states\, considering the requirements of power and energy. The mentioned configuration approaches are demonstrated and validated by simulating ES models for single-unit and multiple-unit paralleled VSG inverters\, analyzing the transient characteristics and performance. \nSpeaker\nMiss Yuqing Cen\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the Speaker\nYuqing Cen received the B.E. degree in measurement control technology and instruments from Guangdong University of Technology\, Guangzhou\, China\, in 2022.

SUMMARY:RPG Seminar – Decision-Dependent Resilience Enhancement for Distribution Systems Against Endogenous Wildfires
DESCRIPTION:Zoom Link: https://hku.zoom.us/j/97816974267?pwd=YzdXMQaxBOpksF0QDz9Bh3Psl6rhrz.1\nMeeting ID: 978 1697 4267\nPassword: 401754 \nAbstract\nThe increasingly frequent wildfires pose significant threats to utility infrastructure and community safety. However\, existing methods that consider decision-dependent uncertainties (DDUs) in system hardening designs typically assume independent line failures\, neglecting the critical interdependencies between line damage statuses under endogenous wildfires ignited by faulted electrical components. These interdependencies render the related resilience enhancement strategies ineffective. To address this gap\, we propose a novel mathematical formulation that simultaneously quantifies various types of DDUs in endogenous wildfires. Furthermore\, we develop a two-stage wildfire-preventive decision-dependent resilience enhancement (WDDRE) model for distribution systems\, integrating the aforementioned DDUs. Numerical experiments demonstrate the effectiveness and superiority of the WDDRE model\, demonstrating its robustness in managing wildfire stochasticity and the DDUs related to planning decisions\, thereby significantly reducing potential wildfire risks. \nSpeaker\nMiss Chenxi HU\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nBiography of the Speaker\nChenxi Hu received the B.E. degree in electrical engineering and automation from Wuhan University\, Wuhan\, China\, in 2020.

SUMMARY:Ubiquitous Sensing in 6G Cellular Networks
DESCRIPTION:Abstract\nRecently\, the International Telecommunication Union (ITU) has identified integrated sensing and communication (ISAC) as a primary usage scenario for the sixth-generation (6G) cellular networks in IMT-2030 Framework. As a result\, future cellular networks will provide not only communication services\, but also sensing services such as localization and tracking. However\, how to exploit the existing communication infrastructure to effectively achieve sensing functions remains an open problem for 6G. In this talk\, we will introduce the methodologies to leverage various types of communication nodes in cellular networks as anchors\, including base stations\, user equipments\, and intelligent reflecting surfaces\, to perform ubiquitous sensing. Specifically\, the advantages and disadvantages of each type of anchors will be listed\, and the efficient solutions to overcome these disadvantages will be outlined. Apart from theoretical works\, this talk will also present our latest achievements in building a 6G ISAC platform that operates at the millimeter-wave band. We will conclude this talk by discussing some promising future directions that will be beneficial to the transformation of the world’s largest communication network into the world’s largest sensing network. \nSpeaker\nDr. Liang LIU\nAssociate Professor\, Department of Electrical and Electronic Engineering\, The Hong Kong Polytechnic University \nBiography of the Speaker\nLiang Liu is currently an Associate Professor with the Department of Electrical and Electronic Engineering\, The Hong Kong Polytechnic University.

SUMMARY:6G Waveforms-Perspectives on Throughput\, Reliability\, and ISAC
DESCRIPTION:Online via Zoom link: https://hku.zoom.us/j/2025021302 \nAbstract\nWith the commercialization of 5G technology\, research on 6G has emerged as a key focus in the field of wireless communications. In this talk\, we explore three candidate waveforms for 6G\, designed to meet its stringent requirements for throughput\, reliability\, and integrated sensing and communications (ISAC). \nWe begin by discussing faster-than-Nyquist (FTN) signaling\, a promising technique for enhancing communication spectral efficiency. The unique challenges associated with equalization and channel coding in FTN systems are highlighted\, along with novel solutions that are benchmarked against theoretical performance limits. \nNext\, we examine orthogonal time frequency space (OTFS) modulation\, which enhances communication reliability in dynamic wireless channels. We demonstrate that OTFS introduces a novel coupling mechanism between information symbols and the wireless channel\, enabling efficient equalization and robust MIMO transmissions by fully exploiting channel dynamics. \nFinally\, we focus on a communication-centric ISAC waveform\, evaluating its sensing performance through ambiguity functions. We analytically prove that OFDM is the optimal waveform for minimizing sidelobes in ranging\, while single-carrier waveforms are superior for Doppler sensing when using practical communication signals. \nThe talk concludes with a discussion of potential future research directions in 6G waveform design\, highlighting open challenges and opportunities in this evolving field. \nSpeaker\nDr. Shuangyang Li\nResearch Assistant\, Faculty of Electrical Engineering and Computer Science\, Technical University of Berlin \nBiography of the Speaker\nShuangyang Li (Member\, IEEE) received the B.S.\, M.S.\, and Ph.D. degrees from Xidian University\, China\, in 2013\, 2016\, and 2021\, respectively.

SUMMARY:Bridging Minds\, Not Just Devices: Semantic and Goal-Oriented Communication for the Internet of Intelligent Things
DESCRIPTION:Abstract\nThe next frontier of the Internet of Things (IoT) lies in transforming today’s smart devices into collaborative cognitive agents – an ecosystem termed the Internet of Intelligent Things (IoIT). While current IoT systems center on raw data exchange\, they fall short of enabling true collaboration: devices cannot share meaningful insights or align their objectives across dynamic\, real-world tasks. This talk presents a paradigm shift – semantic and goal-oriented communication – as the critical enabler for IoIT. I will introduce a theoretical framework that conceptualizes semantic communication through two key challenges: language exploitation and language design. The language exploitation problem focuses on optimizing the encoding and decoding of semantics to minimize distortion without modifying the underlying semantic language. In contrast\, the language design problem seeks to co-optimize both the encoder and decoder through joint source-channel coding\, particularly leveraging deep learning-based approaches. The talk will also explore the role of large language models in learning adaptive semantic representations\, making communication systems more resilient and context-aware. Finally\, I will discuss how the goal-oriented principle broadens classical Shannon theory by integrating decision-making objectives into communication system design. By framing communication as a meaning-driven\, goal-aware process\, we usher in a new era of collective intelligence – one where smart devices evolve into collaborative cognitive agents capable of shared understanding and coordinated action. \nSpeaker\nDr. Yulin SHAO\nAssistant Professor\, State Key Laboratory of Internet of Things for Smart City\, University of Macau \nBiography of the Speaker\nDr. Yulin Shao is an Assistant Professor with the State Key Laboratory of Internet of Things for Smart City\, University of Macau\, and a Visiting Researcher with the Department of Electrical and Electronic Engineering\, Imperial College London.

SUMMARY:Toward Scalable Generative AI via Mixture of Experts in Mobile Edge Networks
DESCRIPTION:Abstract\nThe evolution of generative artificial intelligence (GAI) has driven revolutionary applications like ChatGPT. The proliferation of these applications is underpinned by the mixture of experts (MoE)\, which contains multiple experts and selectively engages them for each task to lower operation costs while maintaining performance. Despite MoE’s efficiencies\, GAI still faces challenges in resource utilization when deployed on local user devices. Therefore\, we first propose mobile edge networks supported MoE-based GAI. Rigorously\, we review the MoE from traditional AI and GAI perspectives\, scrutinizing its structure\, principles\, and applications. Next\, we present a new framework for using MoE for GAI services in Metaverse. Moreover\, we propose a framework that transfers subtasks to devices in mobile edge networks\, aiding GAI model operation on user devices. Moreover\, we introduce a novel approach utilizing MoE\, augmented with Large Language Models (LLMs)\, to analyze user objectives and constraints of optimization problems based on deep reinforcement learning (DRL) effectively. This approach selects specialized DRL experts\, and weights each decision from the participating experts. In this process\, the LLM acts as the gate network to oversee the expert models\, facilitating a collective of experts to tackle a wide range of new tasks. Furthermore\, it can also leverage LLM’s advanced reasoning capabilities to manage the output of experts for joint decisions. Lastly\, we insightfully identify research opportunities of MoE and mobile edge networks. \nSpeaker\nProf. Dusit Niyato\nPresident’s Chair Professor\,\nCollege of Computing & Data Science (CCDS)\,\nNanyang Technological University\, Singapore \nBiography of the Speaker\nDusit Niyato is a President’s Chair Professor in the College of Computing & Data Science (CCDS)\, Nanyang Technological University\, Singapore.

SUMMARY:Advancing Accessible Ultra-low-field MRI with Deep Learning
DESCRIPTION:Abstract\nMagnetic Resonance Imaging (MRI) is a versatile medical imaging modality. Despite its crucial role in modern healthcare\, MRI remains largely inaccessible to the general population. The development of ultra-low-field (ULF) MRI offers opportunities for enabling low-cost\, low-power\, and potentially portable clinical applications. However\, the imaging performance of these emerging ULF MRI scanners remains poor due to the significantly lower signal-to-noise ratio resulting from the weaker magnetic field. Recent advancements in deep learning have opened new frontiers to tackle this unique challenge. This talk will introduce a paradigm shift in improving ULF MR image quality and reconstructing MR image through supervised deep learning techniques. Leveraging existing high-quality high-field MRI data for training\, DL models can recover structural details buried in noise\, artefacts and poor resolution of raw ULF MR images. Such approaches have the potential to overcome the limitations of poor image quality and pave the way for clinical adoption of ULF MRI. \nSpeaker\nDr. Vick Lau\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nBiography of the Speaker\nDr. Vick Lau obtained his MEng degree in Biomedical Engineering from Imperial College London in 2019. He recently received his PhD degree in Electrical and Electronic Engineering from the University of Hong Kong in 2024. His research focuses on the application of deep learning techniques to MRI image processing\, restoration\, reconstruction and analysis\, particularly for ULF and accessible MRI. \nOrganiser\nProf. Ed X.

SUMMARY:Empowering High-Performance Computing Through Heterogeneous Integration of Power Electronics
DESCRIPTION:Abstract\nMost power electronic equipment\, including power supplies for Artificial Intelligence (AI) and high-performance computing systems\, has traditionally been designed using discrete active and passive components. However\, the power electronics industry has reached a stage where improving one performance attribute often comes at the expense of others. As AI and high-performance computing systems demand increasingly higher power levels\, existing power delivery architectures are proving inadequate. Delivering the required power to server racks\, circuit boards\, accelerator cards\, and AI processors has become an escalating challenge. The emergence of wide-bandgap (WBG) power semiconductor devices\, such as silicon carbide (SiC) and gallium nitride (GaN)\, presents a breakthrough opportunity. Compared to silicon (Si) devices\, WBG technologies offer significantly lower losses\, providing a promising solution to the energy challenges of high-performance computing. However\, current design practices often adopt a ‘plug-and-play’ approach\, merely replacing Si with WBG components without altering the underlying design principles. This results in only incremental improvements in efficiency and power density\, leaving the transformative potential of WBG devices untapped. This presentation will explore a paradigm shift in powering AI and high-performance computing systems through the use of high-frequency heterogeneous integration in WBG power electronics design. This innovative approach delivers simultaneous advancements in all critical performance metrics\, including efficiency\, power density\, and electromagnetic compatibility (EMC). Furthermore\, this approach can streamline traditionally labor-intensive manufacturing processes\, paving the way for significant advancements in overall production efficiency. \nSpeaker\nProf. Qiang Li\nFull Professor\,\nCenter for Power Electronics Systems (CPES)\,\nVirginia Tech \nBiography of the Speaker\nQiang Li received the B.S. and M.S. degrees from Zhejiang University\, China\, in 2003 and 2006\, respectively\, and the Ph.D. degree from Virginia Tech\, Blacksburg\, VA\, in 2011. He is currently a Full Professor in the Center for Power Electronics Systems (CPES) at Virginia Tech. His research interests include high-frequency power conversion and control\, high-density electronics packaging and magnetic integration\, as well as power solutions for high-performance computing\, data centers\, electric vehicles\, and energy storage systems.

SUMMARY:EPFL’s Centers Blueprint to Revolutionize Sustainable AI Co-Design and Optimization
DESCRIPTION:Abstract\nArtificial Intelligence (AI) is transforming our world by including self-learning capabilities or extracting intriguing hidden patterns from input data. While the cloud-based computing paradigm has been a baseline approach for AI inferences in recent years\, technological advances and AI optimization methods advocate a shift toward an edge-computing alternative. Nevertheless\, combining cloud computing with the new edge AI paradigm poses storage\, computational\, and efficient communication challenges that must be addressed to support the deployment of compute-intense algorithms in embedded devices. In particular\, with the continuous increase in the quality of their outputs\, large AI models trained in the cloud have high memory and computing requirements that strain our natural resources worldwide and limit their porting in edge nodes. \nAware of this challenge\, the Swiss Federal Institute of Technology Lausanne (EPFL) is studying the problem from different perspectives by combining the works of its different Research Centers. Accordingly\, this presentation will first cover how a multi-center focused approach (in close collaboration with key industrial players) was used to conceive a new energy-efficient AI supercomputer and sustainable data center to explore the cooperation of cloud and edge AI systems. Second\, this presentation will cover a new co-design strategy for new edge AI systems that interact with the latest sustainable data center designs. This new co-design strategy advocates hardware-aware algorithmic transformations of large AI systems to enable accuracy-driven embedded ensembles of convolutional Neural Networks (ECNNs) to improve the accuracy and robustness of final edge devices. Third\, this presentation will discuss the possible use of codebook-based representations\, approximate computing\, and in-memory computing accelerators to reduce further the energy consumption of the next-generation edge AI systems. \nSpeaker\nProf. David Atienza\nEmbedded Systems Laboratory (ESL)\,\nEcole Polytechnique Federale de Lausanne (EPFL)\,\nLausanne\, Switzerland \nBiography of the Speaker\nDavid Atienza is a Professor of Electrical and Computer Engineering\, Heads the Embedded Systems Laboratory (ESL)\, and is the Associate Vice President of Research Centers and Plaforms for the period 2024-2028 at Ecole Polytechnique Federale de Lausanne (EPFL)\, Switzerland.

SUMMARY:EEE MasterClass (EEE 大師講堂) - Controls in Power Systems with High Renewable Penetration
DESCRIPTION:Abstract\nThis presentation will discuss converter control when power systems are operating with high (over 50%) inverter-based renewable generation.  Traditional synchronous generator controls are set to handle transient\, voltage\, damping\, and frequency stability issues arising from contingencies.  With the anticipated retirement of many steam units and increased replacement by renewable resources and storage systems\, the total system inertia and synchronizing torque will be decreased\, affecting power system stability properties and increasing the likelihood of cascading blackouts.  The focus of this talk is to discuss various issues and approaches to enable a smooth transition from fully synchronous generation to a high percentage of renewable resources with inverter interfaces. The topics covered include frequency and voltage regulation\, grid-forming and grid-following converters\, inertia estimation\, transient stability enhancement\, and oscillation detection. The presentation is aimed at addressing an audience with an interest in energy systems and feedback controls. \nSpeaker\nProf. Joe H. Chow\nElectrical\, Computer\, and Systems Engineering\,\nRensselaer Polytechnic Institute \nBiography of the Speaker\nJoe Chow is Institute Professor Emeritus and Senior Research Scientist\, Electrical\, Computer\, and Systems Engineering at Rensselaer Polytechnic Institute\, Troy\, New York.
