Incompletely-known markov decision processes
http://incompleteideas.net/papers/sutton-97.pdf WebA Markov Decision Process (MDP) is a mathematical framework for modeling decision making under uncertainty that attempts to generalize this notion of a state that is sufficient to insulate the entire future from the past. MDPs consist of a set of states, a set of actions, a deterministic or stochastic transition model, and a reward or cost

WebJul 1, 2024 · The Markov Decision Process is the formal description of the Reinforcement Learning problem. It includes concepts like states, actions, rewards, and how an agent makes decisions based on a given policy. So, what Reinforcement Learning algorithms do is to find optimal solutions to Markov Decision Processes. Markov Decision Process. Webpartially observable Markov decision process (POMDP).
