This paper is squarely about machine learning: it proposes a modification to drift-based policy design for offline reinforcement learning, changing how particles repel each other by weighting them with Q-values. The reported results are on OGBench and D4RL AntMaze benchmarks, so the practical question for readers is whether the value-guided repulsion gives a consistent edge over existing baselines beyond these specific tasks.
Value-Guided Repulsion for Offline Reinforcement Learning
arXiv:2610.20190v1 Announce Type: new Abstract: Drifting models have emerged as a highly efficient and stable paradigm for policy design in offline reinforcement learning (RL). However, standard drift policies determine repulsion solely from geometric relationships among generated actions and therefore cannot distinguish them by expected value. To address this limitation, we introduce Value-Guided Repulsion Q-Learning (VRQL) to integrate action value estimates into the particle interaction field. For each state, VRQL combines geometric kernel distance with a normalized Q value scaling. This mechanism assigns greater repulsive influence to particles with lower values while strictly retaining attraction toward behavior action. Consequently, this value-guided interaction field aligns behavior regularization with policy improvement without adding an auxiliary behavior model stage. On 50 OGBench task configurations and 6 D4RL AntMaze configurations, VRQL demonstrates highly competitive performance against established baselines, suggesting that value-guided particle interaction is an effective method for offline RL.
