Abstract
Representation learning plays a crucial role in solving mundane to complex tasks in Artificial Intelligence. Psychologists hypothesized and verified that human beings learn representations from past experiences which are organized as clusters – representations are learned within each cluster and generalized across different clusters. In machine learning, the within-cluster representation learning, e.g., deep learning, has achieved huge success, while it fails on the clusters with insufficient labeled data. Transfer learning, as an effective remedy, discovers and leverages knowledge from the other clusters with abundant data to facilitate representation learning in these clusters. In this talk, I will introduce our efforts towards how to formulate and extract the transferable knowledge. I will also present a novel transfer learning framework which we propose to automatically determine the transferable knowledge by implicitly modelling cluster-to-cluster distances. Some successful applications of transfer learning we have explored are also covered.
