New fine-tuning method preserves offline RL model performance without data retention

Researchers have developed a new method for fine-tuning reinforcement learning models that avoids retaining offline data. This approach, termed "Freeze, Don't Clone," addresses a critical failure mode where continued behavioral cloning after offline data removal leads to representational collapse and loss of action diversity. By freezing the pretrained expressive prior and halting online behavioral fitting, the method significantly improves performance on various OGBench domains across different reinforcement learning algorithms.

IMPACT This research could enable more efficient deployment of reinforcement learning models in scenarios where offline data cannot be retained.

    Freeze, Don't Clone: Fine-Tuning with Expressive Policies Without Retaining Offline Data

    arXiv:2610.36247v1 Announce Type: cross Abstract: Offline-to-online reinforcement learning uses offline pretraining to accelerate subsequent online learning. While many methods assume the offline dataset remains available throughout fine-tuning, there are many settings where this…
