In this paper, we present a decision-theoretic approach to plan inference. Based on the assumption that a rational agent will adopt a plan that maximizes its expected utility, we view plan inference as reasoning about the decision-making strategy of the observed agent. Different from the previous related work, our approach explicitly takes the observed agent's preferences into consideration, and computes the expected utilities of plans to disambiguate competing hypotheses. We use online group
