Introduction

Carrson C. Fung received his B.S. degree from Carnegie Mellon University, Pittsburgh, PA, USA, in 1994, M.S. degree from Columbia University, New York City, NY, USA, in 1996 and Ph.D. degree at The Hong Kong University of Science and Technology in 2005, all in electrical engineering.  He is currently an active member of the IEEE Future Network AIML and massive MIMO working group, focusing his work on advancing HMIMO/UL-MIMO communications using AIML methods.  He was the recipient of the prestigious Sir Edward Youde Ph.D. Fellowship in 2001-2002.  He was the recipient of the National Chiao Tung University College of Electrical & Computer Engineering Excellent Teaching Award in 2011, 2017, and 2018.  He received the National Chiao Tung University College of Electrical & Computer Engineering Outstanding Teaching Award in 2020.  He also received the National Chiao Tung University Excellent Teaching Award in 2019.  He became a fellow of the Advance Higher Education Academy in 2020.  He and his student have won honorable mention in the 2024 student's Master thesis award from the Chinese Institute of Electrical Engineers.  He was a Member of Technical Staff at AT&T and Lucent Technologies Bell Laboratories, Holmdel, NJ, USA, from 1994-1999, where he worked on video and audio coding.  He was also a Researcher at the Hong Kong Applied Science and Technology Research Institute (ASTRI) in 2005, where he worked on MIMO-OFDM systems and a Senior DSP Engineer at Sennheiser Research Lab in Palo Alto, CA, USA, in 2006, where he worked on microphone and microphone array technologies.  He is currently an Associate Professor at the National Yang Ming Chiao Tung University in Hsinchu, Taiwan.  His research interests include network and data science, machine learning for signal processing and communications, and optimization.
 

The Signal Processing and AI Group (SIPAI Group) designs numerical optimization algorithms to solve different machine/deep learning problems and apply the solutions to different applications, such as data association for automotive radar, channel estimation and precoder design for wireless communications, data analysis using distributed and federated learning, and graph signal processing and graph learning for communications and biomedical engineering.  We leverage our knowledge in a signal processing (SP) and numerical optimization during the design process which allows us to extend conventional model-based SP approaches to model/data-driven or pure data-driven algorithms. 
 


Research Topics

Our research basically spans across three different, but integrated, topics:  

1.
graph signal processing (GSP) and graph learning (for non-Euclidean data)
- single- and multilayer attribute graph clustering using AI-based methods
- fast and robust 2nd-order online graph learning using model-based (linear Bayesian filtering) and score-guided generative AI (nonlinear Bayesian filtering) (and perhaps LLM) methods
- we have just started to explore graph (convolutional) neural networks (GNN/GCNN) with the goal doing data analysis and communication problems

2.
distributed and federated learning (DL and FL)
(This work was actually inspired by other automotive radar partner WNC Corp in Taiwan who wanted to design a classification system using their 3D radar)
- we are continuing our work in supervised and unsupervised distributed and federated learning for heterogeneous networks (i.e. with statistical and system (asynchronicity) heterogeneity) using prototype contrastive federated meta learning
- Online federated and distributed learning (data streaming)
- Applications to channel estimation and beamformer design for reconfigurable intelligent surface (RIS) assisted system (see below) with holographic MIMO (HMIMO)
 

3.
6G communications using deep learning
a) modal-domain channel tracking and prediction using score-guided diffusion model and pretrained LLM for holographic MIMO systems (HMIMO)
   - Modal-domain based hybrid beamforming and beamfocusing for near- and far-field users
b) Sensing:  Localization using modal-domain method

c) practical reconfigurable intelligent surface (RIS)
 - modal-domain channel tracking and prediction using score-guided diffusion model and pretrained LLM for RIS-assisted MIMO and HMIMO systems
 - modal-domain hybrid beamforming and beamfocusing
d) low latency and low energy consumption virtual function network design using service chain graphs (related to above work on GNN and GCNN) using reinforcement learning and LLM
e) network orchestration problem and using genAI and LLM model to solve different (cloud-edge) communications and networking problem
