SIFT and University of Edinburgh collaborate on Plan Recognition Research
SIFT Principal Researcher, Dr. Robert Goldman, has recently collaborated with Dr. Christopher Geib of the University of Edinburgh on plan recognition research written up in the paper entitled "Recognizing Plans with Loops Represented in a Lexicalized Grammar." Plan recognition is the problem of attempting to infer an agent's intentions or plans based on observations of the agent's action. This paper addresses a challenging sub-problem, which is to recognize plans involving an indefinite repetition of actions (moving in a direction until you reach a goal, repeating an action until some task is completed, etc.). The research was presented at the national conference of the Association for the Advancement of Artificial Intelligence (AAAI), in San Francisco, CA on August 9, 2011.
