Researchers have introduced a new distributional perspective on knowledge distillation (KD) for language models. This approach moves beyond pointwise comparisons of token distributions to consider a family of multi-temperature views of the teacher model's outputs. The student model is then trained against a geometry-aware aggregate of these views, formalized through various pooling and aggregation methods, including a debiased Sinkhorn-divergence. Experiments on instruction-tuned models reveal that the benefit of multi-temperature aggregation depends on the dispersion of these views, and the optimal KD loss function is contingent on the performance gap between the teacher and student models.
