Challenge: Existing methods for knowledge distillation address the teacher–student capacity gap by mixing teacher and student distributions in the distillation target or using curriculum learning to sequence training from easy to hard examples.
Approach: They propose a white-box KD framework that co-designs curriculum scheduling and target mixing through a unified difficulty-aware principle.
Outcome: The proposed framework outperforms existing methods while reducing training runtime by over 10%.
