On the Off-Policy Teacher in On-Policy Distillation
TL;DR
A new framework called SCOUT enhances on-policy distillation by adapting the teacher model to better handle student-generated prefixes, improving performance across various configurations. This approach addresses the degradation in teacher performance when supervising longer student-generated sequences.
✦ Why It Matters
Implement SCOUT in your OPD workflows to enhance teacher performance and improve learning outcomes.
Key Takeaways
- Adopt SCOUT to improve teacher adaptation in OPD.
- Utilize reinforcement learning for teacher updates.
- Monitor performance improvements across configurations.
- Experiment with different reasoning domains for best results.
How It Works
SCOUT enhances the teacher's ability to adapt to student-generated prefixes by using reinforcement learning. It periodically optimizes the teacher's conditional generation capabilities, allowing it to produce better continuations based on the student's outputs.
This co-training approach ensures that the teacher remains effective even when supervising sequences that it did not originally generate.
