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.

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 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 Finite symmetric groups Sn are essential in fields such as combinatorics, physics, and chemistry. However, learning a probability distribution over Sn poses significant challenges due to its intractable size and discrete nature. We introduce SymmetricDiffusers, a novel discrete diffusion model that simplifies the task of learning a complicated distribution over Sn by decomposing it […]

Through the talk, you will know better on what kind of papers […]

Abstract High penetration of renewable energy poses severe challenges to power system voltage stability due to weakened voltage and reactive power support, complex voltage stability mechanisms, and highly diversified operation states. Traditional control strategies predefined based on limited operation states fail to maintain the required voltage stability margin. This report presents a constraint-learning-based framework for […]

Abstract Since 2016, deep learning techniques have been introduced to solve the inverse problem of MR image reconstruction from undersampled data from accelerated acquisitions. Since then, the field has grown substantially. A wide range of machine learning methods have been developed, translated into clinical practice and adopted as products by all major scanner vendors. In […]
