Reverse-KL Distillation Theory Explores Data Efficiency in Language Model Training

By PulseAugur Editorial · [1 sources] ·

A new research paper explores the theoretical underpinnings of reverse Kullback-Leibler (KL) distillation for training language models. The study investigates the impact of providing the teacher model's full action distribution versus just the probability of a sampled action, and whether online or offline distillation methods are more effective. The findings suggest that offline distillation can achieve optimal rates regardless of the feedback model, while online distillation may require significantly more data when only partial feedback is available. The research also introduces techniques to overcome limitations of standard online objectives, enabling optimal distillation guarantees. AI

    Reverse-KL Policy Distillation: Statistical Guarantees and Limits

    arXiv:2610.30844v1 Announce Type: new Abstract: Reverse Kullback-Leibler (KL) distillation has shown empirical promise for training language models, but its statistical guarantees and limits remain poorly understood. In particular, the effects of two design choices remain unclear…
