New SMAC method enables robust offline-to-online reinforcement learning transfer

Researchers have developed a new method called Score-Matched Actor-Critic (SMAC) to improve the transfer of reinforcement learning models from offline to online environments. Traditional methods often see performance drops when fine-tuning offline-trained models online, a problem attributed to performance valleys in the loss landscape. SMAC addresses this by regularizing the Q-function during offline training, ensuring a smoother transition to online learning. Experiments show SMAC achieves significant regret reduction and maintains performance across various D4RL tasks when transferring to algorithms like Soft Actor-Critic and TD3. AI

IMPACT Enables more stable and effective deployment of reinforcement learning agents in real-world scenarios by improving offline-to-online transfer.

    SMAC: Score-Matched Actor-Critics for Robust Offline-to-Online Transfer

    arXiv:2602.17632v3 Announce Type: replace-cross Abstract: Modern offline Reinforcement Learning (RL) methods find performant actor-critics, however, fine-tuning these actor-critics online with value-based RL algorithms typically causes immediate drops in performance. We provide e…
