Bad-Policy Density: A Measure of Reinforcement Learning Hardness

WebMar 3, 2005 · Summary. We consider non-stationary spatiotemporal modelling in an investigation into karst water levels in western Hungary. A strong feature of the data set is the extraction of large amounts of water from mines, which caused the water levels to reduce until about 1990 when the mining ceased, and then the levels increased quickly. A policy is stationary if the action-distribution returned by it depends only on the last state visited (from the observation agent's history). The search can be further restricted to deterministic stationary policies. A deterministic stationary policy deterministically selects actions based on the current state. Since … See more Reinforcement learning (RL) is an area of machine learning concerned with how intelligent agents ought to take actions in an environment in order to maximize the notion of cumulative reward.

WebFeb 20, 2024 · Finally, we give the connections between the U-average cost criterion and the average cost criteria induced by the identity function and the exponential utility function, and prove the existence of a U-average optimal deterministic stationary policy in the class of all randomized Markov policies. WebA deterministic (stationary) policy in an MDP maps each state to the action taken in this state. The crucial insight, which will enable us to relate the dynamic setting to tradi-tional social choice theory, is that we interpret a determin-istic policy in a social choice MDP as a social choice func-tion.
