Decentralized Learning: Second-order, Online and Robust Algorithms with Convergence Guarantees
My research plan focuses on the second-order, online, and robust algorithms for decentralized machine learning, aiming to propose efficient algorithms with convergence guarantees and study the applications. For example, distributed training with multi-core processors enables faster and more efficient training of machine learning models; wireless sensor networks serve for smart buildings and automatic driving in decentralized manners; hospitals cooperatively study disease prevention and treatment while protecting patients’ privacy.
Big data over geographically distributed devices is the new oil of the digital future. However, due to privacy preservation and communication efficiency issues, we will be unable to mine it within data centres. Instead, we resort to learning over networks. My research plan is to develop second-order, online, and robust decentralized algorithms with convergence guarantees. This plan perfectly fits the themes of Digital Futures: trust, cooperate and learn.
