Advantage-Guided Diffusion for Model-Based Reinforcement Learning

Researchers propose Advantage-Guided Diffusion (AGD-MBRL), a novel approach that improves model-based reinforcement learning by using advantage estimates to guide diffusion models during trajectory generation. The method addresses the short-horizon myopia problem in existing diffusion-based world models and demonstrates 2x performance improvements over current baselines on MuJoCo control tasks.

Scaling Tasks, Not Samples: Mastering Humanoid Control through Multi-Task Model-Based Reinforcement Learning

Researchers propose EfficientZero-Multitask (EZ-M), a multi-task model-based reinforcement learning algorithm that scales the number of tasks rather than samples per task for robotics training. The approach achieves state-of-the-art performance on HumanoidBench with significantly higher sample efficiency by leveraging shared world models across diverse tasks.

Sample-efficient and Scalable Exploration in Continuous-Time RL

Researchers introduce COMBRL, a new reinforcement learning algorithm designed for continuous-time systems using nonlinear ordinary differential equations. The algorithm achieves sublinear regret and better sample efficiency compared to existing methods by combining probabilistic models with uncertainty-aware exploration.
