Abstract

Plan recognition is the process of inferring other agents' plansand goals based on their observable actions. Essentially allprevious work in plan recognition has focused on the recognitionprocess itself, with no regard to the use of the information inthe recognizing agent. As a result, low-likelihood recognitionhypotheses that may imply significant meaning to the observer, areignored in existing work. In this paper, we present novelefficient algorithms that allows the observer to incorporate herown biases and preferences---in the form of a utilityfunction---into the plan recognition process. This allows choosingrecognition hypotheses based on their expected utility to theobserver. We call this Utility-based Plan Recognition (UPR). We briefly discuss a hybrid symbolicdecision-theoretic plan recognizer, and demonstrate the efficacy of thisapproach in an example.
