Research

• Distributed AI (Galaxy Learning): A decentralized machine learning methodology based on Federated Learning. The research focuses on joint modelling for non-IID data, privacy protection, and data ownership and pricing. We are also developing an open source framework for it.
• Computable Social Analytics: Data driven methodology for social science research, including intelligent transportation, smart cites, and neuro-management, etc. We established ZJUCCS as a hub for this research.
