This paper focuses on robust partially observable Markov decision processes (POMDPs), which relax the assumption that probability distributions are precisely known by introducing imprecise probabilities referred to as uncertainty sets. The authors investigate how different assumptions about these uncertainty sets impact optimal policies and values, demonstrating that various semantics lead to distinct policies and values. Additionally, they establish a connection between RPOMDPs and partially observable stochastic games (POSGs), which enables the application of game theory results to RPOMDPs. The study also categorizes existing RPOMDP literature based on uncertainty assumptions, providing clarity on what works operate under. To achieve this, the authors analyze how different uncertainty set assumptions affect optimal policies and values in RPOMDPs.

This paper is about making a type of decision-making process more flexible by allowing for some uncertainty. Right now, these processes assume that we know exactly what might happen next. But what if we’re not sure? This paper shows how different ways of handling this uncertainty affect the best decisions and their values. It also connects these processes to another type of game where players don’t have all the information. This new understanding can help us use results from game theory in these decision-making situations.
