摘要:Transfer learning provides a powerful tool for incorporating multiple related studies into a target study of interest with successful applications in machine learning and biological research. In this talk, I will first introduce the similarity characterization of related tasks and transfer learning algorithms for high-dimensional linear regression. Its theoretical guarantees and minimax optimality will be demonstrated. Next, I will introduce a transferred Q-learning algorithm, which can integrate source data into a target offline or online reinforcement learning problem. Improvement in policy learning will be demonstrated theoretically and numerically.
