Mor Vered, Ramon Fraga Pereira, Maur\'icio Cec\'ilio Magnaguagno, Felipe Meneguzzi, and Gal A. Kaminka. Online Goal Recognition as Reasoning over Landmarks. In AAAI workshop on Plan-, Activity-, and Intent- Recognition (PAIR), 2018.
(unavailable)
Online goal recognition is the problem of recognizing the goal of an agent based on an incomplete sequence of observations with as few observations as possible. Recognizing goals with minimal domain knowledge as an agent executes its plan requires efficient algorithms to sift through a large space of hypotheses. We develop an online approach to recognize goals in both continuous and discrete domains using a combination of goal mirroring and a generalized notion of landmarks adapted from the planning literature. Extensive experiments demonstrate the approach is more efficient and substantially more accurate than the state-of-the-art.
