To address this limitation, we propose a multimodal controllable V2A system that conditions audio generation on a variety of user inputs– such as text, images, or audio– in […]

However, existing imaging devices are constrained by limited field-of-view (FOV) […]

Zoom Link: https://hku.zoom.us/j/93486553339 Abstract The emergence of distributed Mixture-of-Experts (DMoE) systems, which deploy expert models at edge nodes, offers a pathway to achieving connected intelligence in sixth-generation (6G) mobile networks and edge artificial intelligence (AI). However, current DMoE systems lack an effective expert selection algorithm to address the simultaneous task-expert relevance and channel diversity inherent […]

This study investigates the ligand exchange process with different ion pair combinations to improve stability. Surprisingly, altering the ligand ion combinations leads to a deviation from pure blue emission in CsPbBrxCl3-x nanocrystals […]

Abstract 3D Dynamic Meshes can deliver engaging experiences in various applications, but the storage and transmission demands associated with these data structures can be prohibitive. We address this challenge with an efficient compression technique leveraging embedded key nodes. The temporal motion of each vertex is formulated as a distance-weighted combination of transformations from neighboring key […]

Zoom Link: https://hku.zoom.us/j/95380440070 Abstract Complex-valued convolution neural networks (CVCNNs) have been recently applied for modulation recognition (MR), due to its ability to capture the relationship between the real and imaginary parts of the received signal. On the other hand, the transformer model has been shown to be distinguished in MR by its superior capability to […]

Abstract Recent advances in artificial intelligence (AI), especially in large language models (LLMs), have dramatically increased model sizes and computational demands, significantly straining computing system capabilities. This issue is particularly acute in resource-constrained edge AI scenarios, where efficient hardware acceleration of compute-intensive tasks and optimization of data reuse to minimize costly data transfers are essential.

Impressively, it accomplishes this with minimal energy consumption, relying on event-driven signals that travel through its intricate structure. However, replicating […]

Their common operation is to aggregate high-dimensional data, which causes a communication bottleneck that cannot be resolved using traditional orthogonal multi-access schemes. A promising solution, called over-the-air computation (AirComp), exploits channels’ waveform […]

Abstract As the intelligence of everyday smart devices continues to evolve, they can already monitor basic health behaviors such as physical activities and heart rates. The vision of an intelligent health monitoring and intervention pipeline seems to be within reach. How do we get there? In this talk, I will introduce a comprehensive pipeline that […]

Abstract Terahertz (THz) imaging technology is growing rapidly due to its potential applications in material exploration, non-destructive evaluation, industrial inspection, and bioinformatics. However, the practical feasibility of THz imaging systems is significantly constrained by the low efficiency of active THz devices, long imaging acquisition time, insufficient use of THz signal datasets, and their bulky nature. […]

Seminar (1): Navigating Excellence in Transnational Engineering Education: The QMUL-BUPT Joint Programme Experience Speaker: Prof. Michael CHAI, Professor of Internet of Things, Queen Mary University of London Abstract: As global demand grows for engineering graduates equipped with both academic excellence and international perspectives, transnational education (TNE) plays a vital role in redefining the boundaries of global […]

Abstract Intelligent reflecting surface (IRS) is envisioned to be a promising 6G technology which changes wireless communications from “adapting to wireless channels” to “changing wireless channels”. However, current IRS configuration schemes, consisting of sub-channel estimation and passive beamforming, are model-based designs and are difficult to be realized in practical and complex radio environment. To create […]

Abstract The forthcoming sixth generation (6G) wireless networks will be one of the galvanizing technologies for future advanced and autonomous transportation systems. 6G wireless will provide communication services with stringent requirements which are necessary for autonomous driving and on-flight Internet connectivity. Introduction of AI-empowered 6G would guarantee a more intelligent, efficient and secure transportation system. […]
