Applied Machine Learning Deep Generative Models Variational Autoencoders (VAEs) Conditional Inference Responsible AI
Dalhousie University Department of Computer Science

About

Dr. Ga Wu is an Assistant Professor in the Faculty of Computer Science at Dalhousie University, where he leads the Applied Machine Learning Research (DAMLR) Lab. His work is at the intersection of Probabilistic Machine Learning and Deep Learning, with a strong emphasis on Responsible AI and scalability. Dr. Wu’s research focuses on enabling "conditional inference" in deep generative models—allowing complex AI systems like Variational Autoencoders (VAEs) to handle missing data or specific queries more efficiently. Before his academic appointment, he held senior research positions at Twitter (working on extreme-scale recommender systems) and Borealis AI (RBC), experiences that heavily influence his lab's mission to bridge pioneering theoretical AI with robust industrial applications.
