Description

While deep networks show impressive empirical performance, a lot of mysteries remain on how it learns from supervised data and unlabeled data purely with self-supervision. As a result, deep models are often treated as a black-box mapping, cranking out results that might or might not be correct on novel inputs. In this talk, I will give an overview about the teacher-student setting, a methodology used to study how deep models work. In supervised learning, the teacher-student setting treats the labels as generated by a hidden teacher network which typically has a similar architecture as the student network. The existence of the teacher network gives a good reference of the student learning, facilitating the understanding of many of its properties. Besides the overview, I will also introduce some of our very recent works that apply this setting to supervised and self-supervised learning and show interesting insights on how the deep models work.
 

Yuandong Tian is a Research Scientist and Manager in Facebook AI Research, working on deep reinforcement learning, multi-agent learning and its applications, and theoretical analysis of deep models. He is the lead scientist and engineer for ELF OpenGo and DarkForest Go projects. Prior to that, he was a researcher and engineer in Google Self-driving Car team in 2013-2014. He received a Ph.D in Robotics Institute, Carnegie Mellon University in 2013, Bachelor and Master degree of Computer Science in Shanghai Jiao Tong University. He is the recipient of 2013 ICCV Marr Prize Honorable Mentions.
