Federated Learning

Federated learning (FL) has become an effective learning paradigm for distributed computation due to its strong potential in captureing underlying data statistics while preserving data privacy. We aim to develop novel FL frameworks with communication efficiency and privacy preservation for edge computation and IoT intelligences, including GAN-based FL and Graph FL.

Semantic Communication with Generative Learning Models

Semantic Communication is an emerging field of next-generation AI-assisted communication architecture, which offers the capability to regenerate data semantically equivalent to the transmitter side, instead of fully recover the original data by bits. We aim to develop novel semantic communication frameworks via generative learning models to balance the tradeoff of communication efficiency and transmission quality.

Data-Driven Radiomap Estimation, Spectrum Management and Resource Allocation

Providing rich information in propagation behavior and spectrum occupancy, radiomaps could provide detailed spatial information on radio PSD distribution, which consequently benefit applications of resource allocation and spectrum management. We aim to develop novel physics-inspired learning machines for radiomap estimation, together with its applications in network optimization. 

Learning and Signal Processing over High-Dimensional Graphs

To uncover the underlying multilateral and multil-level structures for complex systems and big data, we extend the traditional GSP to high-dimensional graph domains, including hypergraph signal processing (HGSP) and multilayer graph signal processing (M-GSP). We focus on the development of theoretical fundamentals and practical applications for HD graph learning and signal processing.

Physics-Inspired Machine Learning for Imaging and Sensing

To leverage the physics models in machine learning to address the limited quantity and unsatisfying quality of data in realistic applications, we aim to develop physics-inspired machine learning by integrating physical principles and data statistics, which has broad applications in remote sensing, electromagnetic imaging, radiomap reconstruction, and biomedical signal processing.
