Topic: Goal Recognition and Deception of Rational and Irrational Agents.
Speaker: Sebastian Sardinã, Professor at RMIT University.
Abstract
The plan/activity/intention/goal recognition problem is the task of identifying an agent’s intent by observing its behaviour. Traditionally, the problem has involved matching a sequence of observations to a plan in a pre-defined plan library;the winning plan being the one that “best” matches the observations. Recent developments dispense with the overhead of a plan library and instead—based on the assumption that the observed agent is behaving rationally—take a cost-based approach and use classical planning technology to generate candidate plans as needed over a domain model. In this talk, we will review this cost-based approach to goal recognition and some recent results, both for general task planning and path planning. We will present a preliminary framework of deception, and techniques to handle irrational and deceptive agents when performing goal recognition.
