SimTooReal, a platform for robotics teams, now enables live telemetry and failure diagnosis for training runs in Isaac Lab, MuJoCo, Gazebo, and LeRobot with a single command. The tool wraps existing t…
A new arXiv preprint (arXiv:2606.04574) submitted June 3, 2026, presents a hybrid trading architecture that combines statistical pair selection with a Deep Reinforcement Learning execution overlay for…
FeynRL, an algorithm-first framework for post-training and fine-tuning large models, has been released as an open-source tool supporting supervised fine-tuning, preference learning, and reinforcement …
Researchers found that LLM-generated reward functions for sparse reinforcement learning tasks fail in predictable ways, including reward flooding and API misunderstandings. A diagnostic-driven refinem…
Researchers developed a self-play reinforcement learning framework for the four-player imperfect-information card game Big 2, enabling controlled comparisons of different RL agents. Under standardized…
Researchers have developed Differentiable Belief-based Opponent Shaping (D-BOS), a first-order method for multi-agent reinforcement learning that treats an observer's belief as the shaped opponent sta…
Researchers found that removing 25% of transitions from reinforcement learning rollout data stabilizes PPO training by breaking repetitive gradient structures caused by causally chained states. The me…
Here is a 2-3 sentence factual summary of the article: The article describes the process of migrating an online reinforcement learning (RL) training system from the vLLM V0 engine to the V1 rewrite, …
