Web12 mei 2024 · We consider the task of Inverse Reinforcement Learning in Contextual Markov Decision Processes (MDPs). In this setting, contexts, which define the reward and transition kernel, are sampled from a distribution. In addition, although the reward is a function of the context, it is not provided to the agent. Instead, the agent observes … WebMDP, while suggesting empirically that the sample complexity can be changed by a well specified potential. In this work, we use PBRS to construct ⇧-equivalent reward functions in the average reward setting (Section 2.4) and show that two reward functions related by a shaping potential can

In mathematics, a Markov decision process (MDP) is a discrete-time stochastic control process. It provides a mathematical framework for modeling decision making in situations where outcomes are partly random and partly under the control of a decision maker. MDPs are useful for studying optimization … Meer weergeven A Markov decision process is a 4-tuple $${\displaystyle (S,A,P_{a},R_{a})}$$, where: • $${\displaystyle S}$$ is a set of states called the state space, • $${\displaystyle A}$$ is … Meer weergeven In discrete-time Markov Decision Processes, decisions are made at discrete time intervals. However, for continuous-time Markov decision processes, decisions can be made at any time the decision maker chooses. In comparison to discrete-time Markov … Meer weergeven Constrained Markov decision processes (CMDPs) are extensions to Markov decision process (MDPs).
