Researchers have introduced a new framework called missingness-MDPs (miss-MDPs) that integrates the theory of missing data into partially observable Markov decision processes (POMDPs). This novel subclass of POMDPs specifically addresses scenarios where observation functions are missing, detailing the probability of individual state features being unobserved. The work focuses on computing near-optimal policies for miss-MDPs with unknown missingness functions by learning from trajectory data, offering PAC algorithms that yield epsilon-optimal policies with high probability.
