The Optimization, Analytics and Learning (OpAL) Lab is a research group at the Cheriton School of Computer Science. Our work is focused in graph-based machine learning and it involves stronger control on optimization formulations and algorithms, as well as their parallel and communication efficient implementations. We like to view graph-based problems and procedures from an optimization perspective, although they might not always be posed that way. We are equally interested in theory and in practice.
We are located at the University of Waterloo, a vibrant technological hub with Concept, Velocity and Google around the block. We are also part of the Scientific Computation Group and the Waterloo Artificial Intelligence Institute.
We are looking for passionate new PhD students, Postdocs, and Master students to join the team (more info) !
