Policy Synthesis and Reinforcement Learning for Discounted LTL

no code implementations26 May 2023 Rajeev Alur, Osbert Bastani, Kishor Jothimurugan, Mateo Perez, Fabio Somenzi, Ashutosh Trivedi

The difficulty of manually specifying reward functions has led to an interest in using linear temporal logic (LTL) to express objectives for reinforcement learning (RL).

Robust Subtask Learning for Compositional Generalization

1 code implementation6 Feb 2023 Kishor Jothimurugan, Steve Hsu, Osbert Bastani, Rajeev Alur

We formulate the problem as a two agent zero-sum game in which the adversary picks the sequence of subtasks.

Specification-Guided Learning of Nash Equilibria with High Social Welfare

no code implementations6 Jun 2022 Kishor Jothimurugan, Suguman Bansal, Osbert Bastani, Rajeev Alur

Our empirical evaluation demonstrates that our algorithm computes equilibrium policies with high social welfare, whereas state-of-the-art baselines either fail to compute Nash equilibria or compute ones with comparatively lower social welfare.

Compositional Reinforcement Learning from Logical Specifications

1 code implementation NeurIPS 2021 Kishor Jothimurugan, Suguman Bansal, Osbert Bastani, Rajeev Alur

Our approach then incorporates reinforcement learning to learn neural network policies for each edge (sub-task) within a Dijkstra-style planning algorithm to compute a high-level plan in the graph.

Learning Algorithms for Regenerative Stopping Problems with Applications to Shipping Consolidation in Logistics

no code implementations5 May 2021 Kishor Jothimurugan, Matthew Andrews, Jeongran Lee, Lorenzo Maggi

We study regenerative stopping problems in which the system starts anew whenever the controller decides to stop and the long-term average cost is to be minimized.

Abstract Value Iteration for Hierarchical Reinforcement Learning

no code implementations29 Oct 2020 Kishor Jothimurugan, Osbert Bastani, Rajeev Alur

We propose a novel hierarchical reinforcement learning framework for control with continuous state and action spaces.
