Abstract
This paper describes an architecture that combines the complementary strengths of declarative programming, probabilistic graphical models, and reinforcementlearning. Reasoning with different descriptions of incomplete domain knowledge and uncertainty is based on tightly-coupled representations at two different resolutions. For any given goal, non-monotonic logical inference with thecoarse-resolution domain representation provides a plan of abstract actions. Each abstract action is implemented as a sequence of concrete actions byreasoning probabilistically over a relevant part of the fine-resolution representation, committing high probability beliefs to the coarse-resolution representation. Unexplained plan step failures trigger relational reinforcement learning for incremental and interactive discovery of domain axioms. These capabilities are illustrated in simulated domains and on a physical robot in an indoor domain.
