Biography

Chenguang Xiao(肖晨光) is a researcher at China Telecom Bestpay. Previous to that, he was a PhD student in the School of Computer Science. His research interests lie in the conjunction between Federated learning and class imbalance problem under the supervision of Dr. Shuo Wang and Prof. Lee Chapman. Before that, he received a B.Eng. degree in Electrical Engineering and Automation from University of Electronic Science and Technology of China.

Research Interests

• Federated Learning resampling: distributed data resampling/augmentation techniques under privacy constraints
• Model bias reduction: local model bias reduction techniques with heterogeneous data sources
• Federated Learning optimization: advanced optimization algorithms for distributed learning
• Multimodal Machine Learning: Fusion of modalities in complex tasks
