Self Distillation

4 minute read

Published:

Self Distillation has recently come up as a promising direction for language model post training. It targets two major shortcomings of dominant RL based post training algorithms like GRPO. GRPO requires a verifier signal (ex : answer correctness) which might be hard to obtain for tasks where there isnt a clear notion of correctness. GRPO also has a credit assignment problem : for positive advantages, every token in the rollout is equally upweighted. The algorithm cannot assign granular credit to parts of the rollout, unlike its predecessor PPO, which suffers from its own inefficiencies and instabilities.
