SUMMARY:Seminar on Cross-Species Functional MRI (fMRI) Investigations of Reinforcement Learning
DESCRIPTION:Abstract\nReinforcement learning in humans depends on distributed neural circuits for value updating and behavioural adaptation. Cross-species comparisons\, particularly with macaques\, greatly facilitate our understanding of these mechanisms in humans by revealing conserved and evolved elements\, but they crucially depend on precise anatomical alignment to identify homologous regions and interpret functional parallels or divergences across species. \nIn this talk\, I will synthesise recent cross-species fMRI evidence on prefrontal contributions to reinforcement learning. I will first outline key methods for anatomical comparison that enable functional inferences across species despite marked differences in brain morphologies. I will then present findings from reversal learning tasks in humans and macaques\, demonstrating conserved orbitofrontal cortex signals that support rapid value updating in response to changing reward contingencies. Next\, I will discuss anterior cingulate cortex (ACC) activations in both species\, which play a key role in enacting adaptive changes. Finally\, I will highlight the anatomical uniqueness of the human frontopolar cortex (FPC)\, particularly its lateral subdivision\, which lacks a clear homolog in macaques and shows emerging functional importance in our recent findings for handling higher-dimensional aspects of reinforcement learning. \nSpeaker\nProf. Bolton KH CHAU\nDepartment of Rehabilitation Sciences\,\nThe Hong Kong Polytechnic University \nSpeaker’s Biography\nProf. Bolton KH CHAU is an Associate Professor in the Department of Rehabilitation Sciences and Associate Director of the Mental Health Research Centre at The Hong Kong Polytechnic University.

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

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

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

SUMMARY:RPG Seminar – Scaling Up Spatial Awareness: High-Fidelity Data Synthesis for 3D Scene Understanding
DESCRIPTION:Zoom Link:\nhttps://hku.zoom.us/j/91627715757?pwd=ByKZvbK3QYx8VSWXVoNGBsZXTpFEz3.1 \nAbstract\nSpatial understanding constitutes a fundamental pillar of human-level intelligence\, yet its advancement is currently bottlenecked by the scarcity of diverse\, high-fidelity 3D data. Existing research predominantly relies on domain-specific or manually annotated datasets\, creating a critical void: the absence of a principled\, scalable engine capable of synthesizing high-quality spatial data at scale. To address this\, we elucidate the core design principles for robust spatial data generation and introduce OpenSpatial—an open-source engine engineered for high fidelity\, massive scalability\, and broad task diversity. OpenSpatial adopts 3D bounding boxes as the foundational primitive to architect a comprehensive data hierarchy across five essential dimensions: Spatial Measurement\, Spatial Relationship\, Camera Perception\, Multi-view Consistency\, and Scene-Aware Reasoning. Leveraging this infrastructure\, we curate OpenSpatial-3M\, a large-scale dataset that enables models to transition from simple recognition to sophisticated spatial intelligence. Extensive evaluations demonstrate that models trained on our synthesized data achieve state-of-the-art performance across a wide spectrum of benchmarks\, showing substantial and consistent improvements over existing baselines. Furthermore\, we provide a systematic analysis of how synthesized data attributes influence the emergence of spatial perception in vision-language models. By open-sourcing both the engine and the 3M-scale dataset\, we offer a versatile foundation to accelerate future research in generalized 3D scene understanding. \nSpeaker\nMr. Jianhui Liu\nDepartment of Electrical and Computer Engineering\nThe University of Hong Kong \nBiography of the Speaker\nMr. Jianhui Liu is a PhD candidate with the Department of Electrical and Electronic Engineering at the University of Hong Kong. He received the B.Eng. degree in Intelligent Science and Technology from Xidian University in 2021. His research interest lies in machine learning and computer vision\, focusing on Multimodal Large Language Models (MLLMs) for reasoning\, agent\, long video\, spatial intelligence\, unified models\, and their real-world grounding and applications. \nOrganiser\nProf. Xiaojuan Qi\nDepartment of Electrical and Computer Engineering\, The University of Hong Kong \nAll are welcome.

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