A new research paper introduces a "logit distance" metric to better understand the internal representations of machine learning models, particularly language models. This metric aims to provide stronger guarantees for representational similarity when model distributions are close, unlike KL divergence which can fall short. The research demonstrates that using logit distance for distillation can lead to student models that more accurately preserve the linear representational properties and concepts of their teacher models.
