Decision making in incompletely known stochastic systems

WebA Markov Decision Process has many common features with Markov Chains and Transition Systems. In a MDP: Transitions and rewards are stationary. The state is known exactly. (Only transitions are stochastic.) MDPs in which the state is not known exactly (HMM + Transition Systems) are called Partially Observable Markov Decision Processes http://incompleteideas.net/papers/sutton-97.pdf WebThe decision at each stage is based on observables whose conditional probability distribution given the state of the system is known.
