Can partially observable MDPs be fully observable nonetheless?

WebA Partially Observable Markov Decision Process (POMDP) is a tuple , where: (state space), (action space), (transition function), (utility or reward function) form an MDP as defined in chapter 3.1, with assumed to be deterministic 1. is the finite space of observations the agent can receive. is a function . WebGhaoui,2005;Osogami,2012). Although a POMDP can be considered as an MDP with the continuous state space consisting of belief states (Smallwood & Sondik,1973), existing computational procedures for finding the robust policy for an MDP rely on the finiteness of the state space (Nilim & El Ghaoui,2005). A key property of the POMDP is that the ...
