Calibrating Teacher--Student Discrepancy for On-Policy Distillation
TL;DR
Calibrated On-Policy Distillation (Cal-OPD) enhances model training by refining the teacher-student discrepancy, leading to improved performance on reasoning tasks. It retains only the relevant discrepancy, achieving better results than standard methods.
✦ Why It Matters
Implement Cal-OPD in your model training to enhance performance on reasoning tasks today.
Key Takeaways
- Use Cal-OPD to improve model training outcomes.
- Focus on relevant discrepancies to enhance learning.
- Implement privileged interventions for better calibration.
- Evaluate performance improvements across different model sizes.
How It Works
Cal-OPD estimates the teacher's self-deviation by applying positive and negative privileged interventions, which helps isolate the true capability gap between the teacher and student. By calibrating the teacher-student discrepancy, Cal-OPD retains only the relevant components that contribute to effective learning, thus reducing the noise from the teacher's own errors.
