A Bayesian Network Approach to Explainable Reinforcement Learning …

WebIn model-based Bayesian reinforcement learning, the learner starts with a prior distribution over the parameters of T, which we denote by θ. For instance, let θ sas′ = Pr ( s′ s, a, θ) be the unknown probability of reaching s′ when executing a in s. In general, we denote by θ the set of all θ sas′ . Weblike SAT, classical planning, Bayesian networks, and POMDPs. The learning approach has achieved considerable success but results in black boxes that do not have the exibility, transparency, and gen-erality of their model-based counterparts. Model-based approaches, on the other hand, require mod-els and scalable algorithms. Model-free learners ...
