SUMMARY:Fundamental Principle of Magnetic Levitation for AI Driven Maglev Rides
DESCRIPTION:  \nSeminar on “Fundamental Principle of Magnetic Levitation for AI Driven Maglev Rides” \nDear Colleagues and Students\, \nYou are cordially invited to join the upcoming seminar on “Fundamental Principle of Magnetic Levitation for AI Driven Maglev Rides”. Please find the details below. \nDate: 4 November 2024 (Monday)\nTime: 11:00 am – 12:00 noon (HKT)\nVenue: Room 603\, 6/F\, Chow Yei Ching Building\, The University of Hong Kong\nZoom: https://hku.zoom.us/j/97401048897?pwd=WS8LiUbmLYOCce4bIWW8nHbHSDrJg0.1\nMeeting ID: 974 0104 8897\nPassword: 980783\n\nSpeaker\nProf. Joseph Y Hui\nArizona State University \nModerators\nProf. Victor O.K. Li & Prof. Jacqueline C.K. Lam\nDirector & Co-director\,\nHKU-Cambridge AI-WiSe \nAbstract\nElectric propulsion was invented by Michael Faraday who laid the foundation of electric locomotion. Subsequent effort for magnetic levitation has failed to replace wheels as the primary means of reducing impedance to locomotion. My thesis is that levitation should start from Ampere’s law:\n\nBased on this first principle\, I invented and patented a method that will make cars obsolete. Personal AI driven maglev is small\, simple\, silent\, smooth\, speedy\, safe\, smart\, and saving time\, energy and the environment with zero carbon emission. I will demonstrate a working maglev hoverboard and vehicle to show you how personal maglev will change the World. We propose building personal maglev for the Northern Metropolis. We can also increase China’s High Speed Rail throughput 10X and decrease cost to passenger 10X using existing rail infrastructures and individualized AI driven maglev carriages to transport passengers end-to-end without fixed train schedule. \nBiography of the Speaker\nJoseph Y Hui matriculated in 1977 and won the IIE scholarship to attend MIT\, where he earned his BS’81\, MS’81\, EE’82\, and PhD’83 degrees\, all in EECS. He has worked at Comsat\, Bell Labs\, Bellcore\, and IBM. He taught at Columbia University (86-89)\, Rutgers University (89-99)\, Chinese University (95-99)\, and ASU (99 – now). He works on his AWESOME inventions for clean Air\, Water\, and Energy as well as fast and safe travel by Space\, Ocean\, Maglev\, and Eviation. He is an IEEE fellow\, NSF Presidential Young Investigator\, and member of US Academy of Inventors with tens of patents granted.\n\nLooking forward to welcoming you at the seminar next Monday. \nBest Regards\,\nVictor O.K.

SUMMARY:Felix Wu Distinguished Lecture in Power Systems: Change of Paradigm of Power System Operation and Control
DESCRIPTION:Abstract\nSince the inception at the end of the 19th Century\, technical characteristics of power systems have been determined by the physics of synchronous machines (SMs) that convert the primary energy produced by thermal/hydro/nuclear power stations into electricity. However\, the traditional power plants are increasingly being replaced by wind/PV plants and batteries which are connected to the grid asynchronously by means of power electronics (controllable inverters). This means that the power system technical characteristics are increasingly being determined by the control algorithms of inverters rather than the physics of SMs\, and this has profound consequences for power system operation and control. The presentation will discuss those changes and especially the question to what extent inverters can replace synchronous machines. \nSpeaker\nProf. Janusz Bialek\nPrincipal Research Fellow\,\nImperial College London \nBiography of the Speaker\nProfessor Janusz Bialek (FIEEE) is Principal Research Fellow at Imperial College London. Previously\, he held Chair positions at the University of Edinburgh\, Durham University\, Newcastle University and Skolkovo Institute of Science and Technology (Skoltech). Janusz has been PI and Col of multi-million research grants funded by UK research councils and the industry\, and a consultant to the UK government\, European Commission\, and International Energy Agency. He has published widely on integration of renewable generation in power systems\, smart grids\, power system dynamics\, preventing electricity blackouts and power markets. His current main research interests are in addressing the techno-economic challenges posed by increasing penetration of wind/PV/batteries and other devices that are connected to the grid by means of power electronics (programmable inverters)\, rather than synchronous machines\, therefore changing fundamental technical characteristics of the power system. \nOrganiser\nProf. Y.

SUMMARY:Collaboration and Evolution of Foundation and Specialized Models
DESCRIPTION:The seminar scheduled for 24 October 2024 (Thur) has been postponed to 7 November 2024 (Thur)\, and time and venue remain unchanged.\n\n \n\nAbstract\nThe prevailing GPU resource monopoly significantly restricts AI development\, confining participation in the pretraining stages of Large Language Models (LLMs) to a few researchers. This project introduces a novel system that integrates hundreds of domain-specific models to construct a foundational model for Artificial General Intelligence (AGI) with minimal computational demand. By employing smaller\, efficient models\, leveraging top-ranked models across diverse domains through a robust ranking algorithm\, and continuously optimizing the evolving foundation model\, this approach seeks to democratize AI development. It shifts from the traditional ‘model over data’ method to a ‘model over models’ strategy\, aiming to reduce reliance on extensive computational resources and promote broader innovation and inclusivity in AI. \nSpeaker\nProf. Hongxia Yang\nProfessor\,\nDepartment of Computing\,\nThe Hong Kong Polytechnic University \nBiography of the Speaker\nProf. Hongxia Yang\, with over 15 years of experience as an AI scientist\, specializes in large-scale machine learning\, data mining\, and deep learning. Throughout her career\, she has developed 10 significant algorithmic systems\, improving the operations of various enterprises. Her research includes pre-trained models\, big data analytics\, and the practical deployment of large language model(LLM) systems in real settings. Prof. Yang has published more than 100 top-tier papers\, amassed around 10K citations with an H-index of 44\, and holds over 50 patents. She has received several awards\, including the 2019 SAIL Award at the World Artificial Intelligence Conference and the 2020 National Science and Technology Progress Award\, China’s top tech accolade. Named one of Forbes China’s Top 50 Women in Tech in 2022 and AI 2000 Most Influential Scholar Award in 2023-2024\, Prof. Yang has held prominent roles at ByteDance US\, Alibaba Group\, Yahoo!

SUMMARY:The Sound of Music at the Nanoscale – Exploring the Nanoscale World with NEMS Resonators Based on Low Dimensional Nanomaterials
DESCRIPTION:Abstract\nThe advent of low-dimensional nanostructures has enabled a plethora of new devices and systems. Among them\, nanoelectromechanical systems (NEMS) offers the unique capability of coupling the exquisite material properties found in these atomically-defined nanostructures with their mechanical degree of freedom\, opening new opportunities for exploring exotic phenomena at the nanoscale. In particular\, as these devices driven into mechanical vibration—just as musical instruments—they become essentially nanoscale guitars\, drums\, tuning folks\, etc. By studying the infinitesimal mechanical vibrations in these nanoscale “music instruments”\, i.e.\, listening to the “sound of music” at the nanoscale\, researchers can study a number of fundamental physical processes such as absorption\, phase transition\, anisotropy\, and nonlinear processes. \nSpeaker\nProf. Zenghui Wang\nInstitute of Frontier and Fundamental Sciences\,\nUniversity of Electronic Science and Technology of China \nBiography of the Speaker          \nZenghui Wang is currently a professor in the Institute of Frontier and Fundamental Sciences (IFFS) at the University of Electronic Science and Technology of China (UESTC). His research interests and expertise primarily focus on nanoscale devices and systems\, particularly Nanoscale Resonators\, and High-Frequency Resonant Sensors & Transducers. Prior to joining Case\, during 2010-2012\, he worked at Cornell University as a postdoc researcher. He earned a Ph.D. degree (2010) from University of Washington\, Seattle\, for building an ultra-high frequency NEMS resonant sensor with an individual single-walled carbon nanotube\, and using it to detect and study the low-dimensional phase transitions of the atomic layer adsorbed on the nanotube surface. He is an expert on studies of emerging nanoscale devices and sensors based on new materials such as carbon nanotubes\, graphene\, and other low-dimensional nanomaterials\, and has published 20+ research articles in peer-reviewed journals\, including Science\, Nature Physics\, Nature Nanotechnology\, Nature Communications\, Science Advances\, Nano Letters\, ACS Nano\, Physical Review Letters\, 2D Materials\, etc.\,.

SUMMARY:Towards Provable Unaligned Multimodal Learning: A Model Identification Perspective
DESCRIPTION:The seminar scheduled for November 19\, 2024 (Tue) will start earlier at 1:30 pm\, while the date and venue will remain unchanged.\nAbstract\n2023 was “the year of AI”\, highlighted by the release of numerous AI models with remarkable capabilities. Multimodal learning is at the forefront of AI advancements\, with state-of-the-art models like GPT-4 and Gemini emphasizing multimodal functionalities as their defining features. Despite its importance\, many aspects of multimodal learning\, and AI developments in general\, still lack a concrete and comprehensive understanding—which is essential for building resilient and trustworthy systems. Our research focuses on the understanding of AI/ML systems to drive theory-backed advancements. From this perspective\, this presentation revisits a core component of multimodal learning—Unsupervised Domain Translation (UDT). Many UDT systems\, such as CycleGAN\, use Distribution Matching (DM) modules\, which often fail in content-aligned translations due to measure-preserving automorphism (MPA). Existing remedies fall short of guaranteed performance. In my talk\, I will introduce a model identification perspective for UDT\, overcoming the MPA issues and ensuring identifiability of the desired translation functions. This is the first proven identification result in UDT under CycleGAN’s settings\, to our knowledge. We have also broadened these concepts\, providing solutions for various translation challenges\, enabling provable content-style disentanglement\, and offering more versatile cross-domain data generation. These advancements promise significant theoretically supported enhancements for UDT applications\, particularly in annotation-limited fields such as medicine and biology. \nSpeaker\nProf. Xiao Fu\nAssociate Professor\,\nOregon State University \nBiography of the Speaker\nXiao Fu has been with the School of Electrical Engineering and Computer Science\, Oregon State University since 2017\, where he is currently an Associate Professor. He received the Ph.D. degree in Electronic Engineering from The Chinese University of Hong Kong\, in 2014. He was a Postdoctoral Associate with the Department of Electrical and Computer Engineering\, University of Minnesota – Twin Cities\, from 2014 to 2017.

SUMMARY:Low-coherence Biophotonics Imaging for the Brain
DESCRIPTION:Abstract\nThis talk will highlight our recent efforts to explore the brain using low-coherence light. We will discuss two key scenarios: intraoperative assessment of brain cancer infiltration in patients and real-time imaging of dynamic neural activities in freely behaving rodents. In the first scenario\, focused on clinical translation\, we developed a quantitative color-coded optical coherence tomography (OCT) technology. This provides neurosurgeons with direct visual cues based on the intrinsic optical properties of tissues\, enabling them to maximize cancer resection while minimizing damage to healthy brain tissue. Our results from over 50 patients demonstrate excellent specificity and sensitivity. For the second scenario\, which pertains to basic research\, we created the first all-fiber-optic\, head-mounted\, ultracompact (~2 mm diameter)\, and ultralight (<1 g) two-photon fiberscopy platform. This allows for high-resolution imaging of neuronal activity in freely walking or rotating mice. We will discuss recent advancements\, including a 15X increase in the area field of view through cascaded magnification\, facilitating the imaging of multiple neurons and their functional correlations within a single frame. Additionally\, we achieved a significant increase in imaging frame rates (10-30 times faster\, reaching video rates) through an improved scanner design and a two-stage deep learning strategy. Detailed neural imaging results will be presented at the seminar\, and if time permits\, we will also explore other applications of these technologies for noninvasive in vivo optical histology. \nSpeaker\nProf. Xingde Li\nDepartment of Biomedical Engineering\,\nJohns Hopkins University \nBiography of the Speaker\nXingde Li earned his PhD in Physics from the University of PENN in 1998. Following 3 years of postdoctoral training at MIT\, he began his academic career as Assistant Professor at the University of Washington.

SUMMARY:Data-Centric Architecture and Algorithm Co-design for Data-Intensive Modern Applications
DESCRIPTION:Mode: Online via Zoom\nZoom Link: https://hku.zoom.us/j/97278710788?pwd=VOGfxnayhDjXu3PTxj37IfWDzCGQ1i.1\nMeeting ID: 972 7871 0788\nPassword: 533887 \nAbstract\nIn today’s digital landscape\, the exponential growth of data has become the driving force behind modern applications\, such as genome analysis and machine learning applications\, revolutionizing our approach to healthcare and overall living quality. However\, this unprecedented deluge of data poses a formidable challenge to traditional von Neumann computer architectures. The inefficiencies arising from the constant data movement between processors and memory consume a substantial portion of both execution time and energy when running modern applications on conventional von Neumann computers. To reduce this significant data movement\, data-centric architectures\, particularly processing-in-memory accelerators\, emerge as a promising solution by enabling the processing of data directly where it resides. Nonetheless\, most existing data-centric architectures primarily focus on accelerating specific arithmetic operations\, inadvertently leaving a substantial gap between the architectural enhancements and the holistic needs of modern applications. Concurrently\, conventional software optimizations often treat the architecture as a black box\, which inherently limits the potential acceleration of applications. \nThis talk seeks to bridge the gaps between modern applications and data-centric architectures and revolutionize the landscape of data-centric acceleration. First\, this talk delves into the distinctive features of modern applications\, illustrating these features with a focus on genome analysis within the realm of bioinformatics. Second\, challenges arise when data-intensive modern applications are executed on conventional computers. The talk then transitions to a compelling remedy: the adoption of a data-centric architecture. Third\, this talk outlines the intricacies involved in designing a data-centric architecture for modern applications. It explores the challenges inherent in this process and concurrently offers potential solutions. Following this analysis\, the talk advances to put forth an innovative architecture specifically designed for genome analysis via algorithm-architecture co-design. In conclusion\, the talk wraps up with a summary and a glimpse into future avenues of exploration. \nSpeaker\nDr. Haiyu Mao\nLecturer (Assistant Professor)\,\nDepartment of Engineering\,\nKing’s College London \nBiography of the Speaker\nDr. Haiyu Mao is a Lecturer (Assistant Professor) in the Department of Engineering at King’s College London.

SUMMARY:Integrated Sensing and Communications: From Signal Processing to Prototype
DESCRIPTION:Abstract\nIntegrating sensing functionality into communication devices is emerging as a key feature of the 6G Radio access network. Dual-function radar communication (DFRC) systems implement both sensing and communication using the same hardware thus saving in power\, cost and spectral efficiency. In this talk\, we focus on some of the signal processing aspects of designing and implementing DFRC systems and discuss how the convergence of sensing and communication can be utilized to efficiently exploit congested resources and to communicatee intelligence via sensing.  In particular\, we begin by introducing several approaches to reduce hardware cost by exploiting sub-Nyquist principles and sparse arrays to sense and communicate jointly at low sampling and bit rates. We then introduce new hardware designs that allow continuous monitoring using event-based sampling and high dynamic range. We next consider several different approaches to waveform design and receive signal processing considering both radar detection mode and target localization including spectrum sharing\, joint precoder design\, and index modulation techniques. Our approaches allow design flexibility in trading off radar and communication performance\, while preserving the radar ambiguity function. We end by discussing future trends in DFRC systems including model-based AI for communication and radar under uncertain channels\, near-field communication and radar\, and hybrid RIS/DMA to create configurable radiation patterns for scalable and low power sensing and communication. Throughout the talk we will consider both the theory and hardware prototypes and show several demos of real-time DFRC systems\, low bit and low power ADCs\, and cognitive joint radio and radar systems. \nSpeaker\nProf. Yonina Eldar\nWeizmann Institute of Science\, Israel \nBiography of the Speaker\nYonina Eldar is a Professor in the Department of Mathematics and Computer Science\, Weizmann Institute of Science\, Rehovot\, Israel where she heads the Center for Biomedical Engineering and Signal Processing and holds the Dorothy and Patrick Gorman Professorial Chair.

SUMMARY:RPG Seminar – High-performance E-mode GaN HEMTs and Inverters Using a CTL-based Monolithically Integrated Platform for Power ICs Applications
DESCRIPTION:Abstract\nGaN high-electron-mobility transistors (HEMTs) have been extensively studied and commercialized due to their superior material properties for high-frequency and high-power applications. To fully harness their potential\, GaN-based power ICs have been proposed to develop energy-efficient\, high-density integrated circuits and systems. \nTo ensure fail-safe operation\, minimize standby power consumption\, and facilitate circuit simplicity\, enhancement-mode (E-mode) GaN HEMTs with high VTH are required. Moreover\, E-mode GaN HEMTs in direct-coupled FET logic (DCFL) integration show considerable advantages and promising potential for GaN power IC applications. \nIn this seminar\, we will introduce a novel charge trapping layer (CTL)-based monolithically integrated platform to address existing technological challenges and demonstrate high-performance E-mode GaN HEMTs and inverters for power IC applications. This work offers a promising approach for implementing E-mode GaN HEMTs with high VTH and excellent breakdown characteristics without performance degradation. It unlocks their potential for the monolithic integration of GaN HEMTs. \nSpeaker\nMr. Jiang Yang\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong \nBiography of the speaker\nMr. Jiang Yang received his Bachelor of Science (B.S.) degree from the Southern University of Science and Technology (SUSTech)\, Shenzhen\, China\, in 2019.

SUMMARY:RPG Seminar – Electrically Reconfigurable Surface Acoustic Wave Phase Shifters Based on ZnO TFTs on LiNbO3 Substrate
DESCRIPTION:Abstract\nReconfigurable surface acoustic wave (SAW) phase shifters are emerging as important components for advancing secure wireless communication\, adaptable signal processing\, and intelligent sensing technologies.   A promising approach to SAW modulation involves gate voltage-controlled tuning through acoustoelectric interactions\, which offers efficient modulation at low bias voltages.   However\, current acoustoelectric devices face limitations\, such as restricted tunability\, complex heterostructures\, and demanding fabrication processes\, hindering their practical deployment. \nIn this seminar\, we will introduce a new voltage-tunable SAW phase shifter material system\, based on an atomic layer deposition (ALD) ZnO thin-film transistor (TFT) integrated with a LiNbO3 substrate. This novel structure leverages the high electromechanical coupling coefficient (K²) of LiNbO3 and the superior conductivity tuning capability of ZnO\, while also featuring a simplified architecture that facilitates fabrication.  This ZnO-on-LiNbO3 platform holds promise for a broad range of applications requiring adaptable acoustic components. \nSpeaker\nMr. Zhang Yi\nDepartment of Electrical and Electronic Engineering\,\nThe University of Hong Kong\n \nBiography of the speaker\nZhang Yi is a Ph.D. candidate at The University of Hong Kong specializing in the design and fabrication of MEMS-based piezoelectric acoustic wave devices.

SUMMARY:RPG Seminar – Design of High-Performance Microwave Active Circuits Using Synthesis Techniques
DESCRIPTION:Abstract\nMicrowave active circuits\, such as low-noise amplifiers\, power amplifiers\, and oscillators\, are essential components of the transceivers in the front-end of RF communication systems. As modern communication systems evolve\, the demand for higher performance increases. This necessitates compact circuit designs for integration applications\, along with reduced jitter and bit error rates for enhanced communication accuracy. Additionally\, multi-functionality\, such as multi-band operation\, is currently the research hotspot. However\, achieving these high-performance goals with existing circuit design methods\, which are generally based on experience and trial-and-error\, is often time-consuming and lacks a systematic design approach. \nIn this seminar\, we will introduce a series synthesis techniques for microwave active circuits. Using these techniques\, we have developed oscillators with ultra-low phase noise\, an ultra-wideband voltage-controlled oscillator (VCO)\, and dual-band power amplifier circuits. Simulation and measurement results demonstrate that these novel circuits achieve state-of-the-art performance compared to existing designs. \nSpeaker\nMiss Sun Menghan\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the speaker\nMenghan Sun received the B.S. degree from the University of Electronic Science and Technology of China\, Chengdu\, China\, in 2020.

SUMMARY:RPG Seminar – Decision-Oriented Modeling in Building Energy Systems
DESCRIPTION:Abstract\nBuilding energy systems (BESs) serve as crucial flexible resources within power systems. Among various building load types\, thermostatically controlled loads (TCLs) for indoor temperature regulation are the primary contributors to flexible grid services. To harness this flexibility\, it is essential to acquire a thermal dynamics model that represents temperature variations influenced by TCLs. Data-driven methods are commonly employed to capture thermal dynamics accurately\, and model performance is assessed using statistical metrics\, such as mean square error. However\, this approach may lead to biases in model applications because of the unaligned modeling errors and application objectives. In other words\, maximal model accuracy does not necessarily translate to maximal application objectives in terms of actual thermal dynamics within buildings. \nTo tackle this problem\, our research focuses on a new perspective of decision-oriented modeling of thermal dynamics\, ensuring that the modeling objectives are closely aligned with application purposes. We demonstrate the potential of the perspective through two topics: individual building modeling for energy-efficient temperature control\, and multiple building modeling for flexibility aggregation. \nSpeaker\nMr. Cui Xueyuan\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the speaker\nXueyuan Cui received the B.E. degree and the M.S. degree from Zhejiang University\, Hangzhou\, China\, in 2019 and 2022.

SUMMARY:RPG Seminar – Learning-Assisted Optimal Power Flow for Power Systems: Addressing Feasibility\, Adaptability\, and Scalability Issues
DESCRIPTION:Abstract\nOptimal Power Flow (OPF) problem has been studied for many years. Traditionally\, this problem is solved using an iterative algorithm like the Interior Point Method (IPM). However\, due to the non-convex and nonlinearity of the OPF problem\, it is challenging for iterative algorithm to meet the real-time requirement of power system operation and security analysis. Thanks to the powerful fitting capabilities of the machine learning models and the fact that they can provide a solution in real time\, leveraging such models to solve the OPF problems has become a hot topic. Even though a large number of papers are published to expedite the solving process\, three primary issues are hindering their application. In this seminar\, we would like to address feasibility\, adaptability\, and scalability issues of the existing data-driven OPF methods by employing learning and optimization. Additionally\, we will also discuss open issues in machine learning for solving OPF problem. \nSpeaker\nMr. Jia Yixiong\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the speaker\nYixiong Jia received the B.S. degree in science from Northwest Agriculture and Forestry University and the M.S. degree in electronic science and technology from ShanghaiTech University\, Shanghai\, China\, in 2019 and 2022\, respectively.

SUMMARY:RPG Seminar – Multi-time-scale management of virtual power plant for frequency regulation service provisio
DESCRIPTION:Abstract\nRenewable integration in power systems causes a surge of frequency fluctuations\, primarily due to the intermittent nature of renewable energy. To address this challenge\, distributed energy resources (DERs) pave one promising way for frequency regulation by their aggregation as a virtual power plant (VPP). However\, the technical heterogeneity of DERs results in varying frequency regulation performance across different DER portfolios. To promote the performance-based profit for frequency regulation\, we propose a data-driven approach to model the frequency regulation performance with the DER portfolio\, which is integrated into a VPP’s operation schemes. On this basis\, the optimal operations of the VPP in different time scales are explored for frequency regulation service provision\, including both hour-ahead frequency reserve bidding and real-time reserve activation. A comprehensive technical and economic analysis is conducted to validate the effectiveness of the proposed approach in enhancing VPP’s profit for frequency regulation service provision. \nSpeaker\nMiss Huang Mingyu\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the speaker\nMingyu Huang received the B.S. degree in automation and the M.S. degree in control science and engineering from Wuhan University\, Wuhan\, China\, in 2019 and 2022\, respectively.

SUMMARY:RPG Seminar – Wireless Sensing for Speech Recovery and Recognition
DESCRIPTION:Abstract\nConsidering the microphone is easily affected by noise and soundproof materials\, the radio frequency (RF) signal is a promising candidate to recover audio as it is immune to noise and can traverse many soundproof objects. We introduce Radio2Speech\, a system that uses RF signals to recover high quality speech from the loudspeaker. Radio2Speech can recover speech comparable to the quality of the microphone\, advancing from recovering only single tone music or incomprehensible speech in existing approaches. Quantitative and qualitative evaluations show that in quiet\, noisy and soundproof scenarios\, Radio2Speech achieves state-of-the-art performance and is on par with the microphone that works in quiet scenarios. Moreover\, millimeter wave (mmWave) based speech recognition provides more possibility for audio-related applications\, such as conference speech transcription and eavesdropping. However\, considering the practicality in real scenarios\, latency and recognizable vocabulary size are two critical factors that cannot be overlooked. We also propose Radio2Text\, the first mmWave-based system for streaming automatic speech recognition (ASR) with a vocabulary size exceeding 13\,000 words. The experimental results show that our Radio2Text can achieve a character error rate of 5.7% and a word error rate of 9.4% for the recognition of a vocabulary consisting of over 13\,000 words. \nSpeaker\nMr. Zhao Running\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the speaker\nRunning Zhao is pursuing the Ph.D. degree with the Department of Electrical and Electronic Engineering at the University of Hong Kong\, and he is advised by Edith C.H.

SUMMARY:RPG Seminar – Discrimination of Developmental Trajectories in Brain Structural Features of ASD
DESCRIPTION:Zoom ID: 998 6183 8733\nPassword: 275656 \nAbstract\nAutism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by challenges in social interaction\, communication\, and repetitive behaviors. Structural brain abnormalities associated with ASD are known to evolve across the developmental trajectory\, making it difficult to identify consistent biomarkers for accurate individual diagnosis. In this seminar\, we explore age-related variations in cortical thickness (CT) and gray matter volume (GMV) using a novel Partial Least Squares (PLS)-based method combined with feature selection techniques. Key findings reveal significant developmental abnormalities in several brain regions\, which were strongly correlated with behavioral measures such as Autism Diagnostic Observation Schedule (ADOS) scores. The incorporation of age-related features not only enhanced classification accuracy but also provided new insights into the developmental and behavioral mechanisms underlying ASD. These results highlight the critical role of age in understanding ASD and improving diagnostic and therapeutic strategies. \nSpeaker\nMs. Guo Zifan\nDepartment of Electrical and Electronic Engineering\nThe University of Hong Kong \nBiography of the speaker\nZifan Guo received the B.S. degree from the University of Electronic Science and Technology of China\, Chengdu\, China\, in 2021.
