Domain Adaptive Imitation Learning with Visual Observation

no code implementations NeurIPS 2023 Sungho Choi, Seungyul Han, Woojun Kim, Jongseong Chae, Whiyoung Jung, Youngchul Sung

In this paper, we consider domain-adaptive imitation learning with visual observation, where an agent in a target domain learns to perform a task by observing expert demonstrations in a source domain.

A Variational Approach to Mutual Information-Based Coordination for Multi-Agent Reinforcement Learning

no code implementations1 Mar 2023 Woojun Kim, Whiyoung Jung, Myungsik Cho, Youngchul Sung

In this paper, we propose a new mutual information framework for multi-agent reinforcement learning to enable multiple agents to learn coordinated behaviors by regularizing the accumulated return with the simultaneous mutual information between multi-agent actions.

Quantile Constrained Reinforcement Learning: A Reinforcement Learning Framework Constraining Outage Probability

1 code implementation28 Nov 2022 Whiyoung Jung, Myungsik Cho, Jongeui Park, Youngchul Sung

This paper proposes a framework, named Quantile Constrained RL (QCRL), to constrain the quantile of the distribution of the cumulative sum cost that is a necessary and sufficient condition to satisfy the outage constraint.

A Maximum Mutual Information Framework for Multi-Agent Reinforcement Learning

no code implementations4 Jun 2020 Woojun Kim, Whiyoung Jung, Myungsik Cho, Youngchul Sung

In this paper, we propose a maximum mutual information (MMI) framework for multi-agent reinforcement learning (MARL) to enable multiple agents to learn coordinated behaviors by regularizing the accumulated return with the mutual information between actions.

Population-Guided Parallel Policy Search for Reinforcement Learning

1 code implementation ICLR 2020 Whiyoung Jung, Giseung Park, Youngchul Sung

In the proposed scheme, multiple identical learners with their own value-functions and policies share a common experience replay buffer, and search a good policy in collaboration with the guidance of the best policy information.
