Abstract: Message passing is the essential building block in many machine learning problems such as decentralized learning and graph neural networks. In this talk, I will introduce several innovative designs of message passing schemes that address the efficiency and security issues in machine learning. Specifically, first I will present a novel decentralized algorithm with compressed message passing that enables large-scale, efficient, and scalable distributed machine learning on big data. Then I will show how to significantly improve the security and robustness of graph neural networks by exploiting the structural information in data with a novel message passing design.
