Try an Advantage Estimator When OPSD Collapses
willccbb · x · 2026-07-11
The author shares a practical troubleshooting tip for tackling model collapse during OPSD training:
- When the training process repeatedly collapses, first try removing the hinted logprob ratio.
- Then, replace it with an advantage estimator.
Though brief, this provides a clear fault localization method and alternative solution, serving as highly actionable debugging advice for training.
