Topic: Feature-based Generalized Policies and Guarantees
Speaker: Prof. Blai Bonet, retired Professor of Computer Science from Universidad Simón Bolívar, and currently research associate at the Universitat Pompeu Fabra, Barcelona, Spain.
Abstract
In recent years, generalized planning has become an important thread in planning and deep reinforcement learning (DRL). In the logical setting, a successful approach for generalized planning is to express general policies or strategies with rules over state features as the latter provide the necessary abstraction over classes of planning instances with different sets of grounded actions, and the rules tell which transition to take at non-goal states. Furthermore, the same type of rules can also be used to express general strategies based on subgoal-based decompositions that are guarantee to be executable in polynomial time. In this talk, we revise the main ideas underlying these approaches and address the task of establishing formal guarantees for general policies.
