Self-Supervised Theorem Discovery in a Formal Axiomatic System

Kazuki Ota, Takayuki Osa, Tatsuya Harada

Recent artificial intelligence (AI) systems have shown remarkable progress in mathematical reasoning. Many existing approaches, including large language models (LLMs), draw on huma…

Revisiting Regularized Policy Optimization for Stable and Efficient Reinforcement Learning in Two-Player Games

Kazuki Ota, Takayuki Osa, Motoki Omura +1

Two-player games such as board games have long been used as traditional benchmarks for reinforcement learning. This work revisits a policy optimization method with reverse Kullback…

Gradual Transition from Bellman Optimality Operator to Bellman Operator in Online Reinforcement Learning

Motoki Omura, Kazuki Ota, Takayuki Osa +2

For continuous action spaces, actor-critic methods are widely used in online reinforcement learning (RL). However, unlike RL algorithms for discrete actions, which generally model…

Offline Reinforcement Learning with Wasserstein Regularization via Optimal Transport Maps

Motoki Omura, Yusuke Mukuta, Kazuki Ota +2

Offline reinforcement learning (RL) aims to learn an optimal policy from a static dataset, making it particularly valuable in scenarios where data collection is costly, such as rob…
