Transfer
learning is one way to close the gap between the apparent speed of
learning of humans in novel domains and the relatively slow pace of
learning of machines. Transfer is doubly beneficial in reinforcement
learning where the agent not only needs to generalize from sparse
experience, but also needs to discover good opportunities to learn in
the first place. In this paper, we show that the hierarchical Bayesian
framework can be readily adapted to sequential decision problems and
provides a natural formalization of transfer learning. We present
positive transfer results in learning action models and policies in
this framework through empirical evaluations in real-time strategy
games.
