Expert Talk “Neurosymbolic learning via Integration of (Relational) Planning and (Deep) RL” with Sriraam Natarajan

July 20, 2023, 3:00 pm - 4:30 pm CEST

Expert Talk Sriraam Natarajan

About the Talk:
One of the challenges in constructing a two level system, for instance, a higher-level deliberative planner with a lower level reactive RL agent, is the interface between these two systems. In this talk, I argue that this interface is crucial in constructing appropriate abstractions for the underlying RL agent to be efficient and effective. Specifically, I outline our RePReL system that constructs these abstractions automatically using a dynamic Statistical Relational Learning (SRL) language. Our experiments show that RePReL framework not only achieves better performance and efficient learning on the task at hand but also demonstrates better generalization to unseen tasks. The interface layer allows for the RL and planner components to be a plug and play system and I demonstrate the versatility of our approach on several tasks. This is joint work with our PhD student Harsha Kokel, Prasad Tadepalli and Balaraman Ravindran.
