Lingyang Chu
Ph.D.
I am an assistant professor at McMaster University. Before joining McMaster University, I was a postdoc fellow at Simon Fraser University. I obtained my Ph.D. degree in Computer Science from University of Chinese Academy of Sciences.
Research Interest
My research interest lies broadly in the areas of data mining, machine learning and statistics. My recent research focuses on trustworthy artificial intelligence (AI), which includes privacy, interpretability, security, robustness, and fairness of modern machine learning models, especially, deep neural networks. I am also an expert in federated learning, graph based machine learning, and scalable data mining on large graphs. Many of my previous research outcomes have been successfully deployed as services and products of Huawei Cloud. For example, a personalized federated learning system was deployed as a core service on tens of millions of smart phones running Harmony OS.Recruiting

[General] I am recruiting highly motivated students to conduct cutting-edge research on interpreting deep models, defending against adversarial attacks and building next-generation reliable computing frameworks. Please send me your transcript(s) and CV if interested.
Selected Publications
Research is a life-long journey, with problems to solve, knowledges to gain, but most of all, experiences to enjoy.
