Not Every Divergence Should Be Suppressed: Counterfactual Recoverability in On-Policy Distillation
TL;DR
Counterfactual recoverability in on-policy distillation (OPD) allows for better decision-making in training by categorizing error states, leading to improved performance metrics. This method outperforms traditional divergence-based approaches significantly.
✦ Why It Matters
Implement counterfactual recoverability in your OPD training to enhance model performance today.
Key Takeaways
- Utilize counterfactual recoverability to classify error states in training.
- Implement teacher-continuation and rollback branches for error evaluation.
- Focus on retaining teacher-correctable prefixes for better outcomes.
- Adopt recoverability-aware control methods to improve performance metrics.
How It Works
The mechanism involves replaying error states through two branches: a teacher-continuation branch that continues from the error state and a rollback branch that reverts to a previous state. By comparing the outcomes of these branches, the model can categorize states as recoverable or irreversible, guiding the training process on how to handle each trajectory.
