Title: A Robust Approach to Plan Recognition Abstract: Plan recognition is the process of inferring an agent's plans and goals from his actions. Most of the previous work on plan recognition has approached this problem by first hypothesizing a single goal and then attempting to match the actions with a plan for achieving that goal. Unfortuantely, there are some types of problems where focusing on a single hypothesis will mislead the system. I will present an architecture for plan recognition that does not require the system to choose a single goal, but allows several hypotheses to be considered simultaneously. This architecture uses an assumption-based truth maintenance system to maintain both the observed actions and the predictions about the agent's plans and goals.
