Researchers have introduced a new framework for knowledge distillation that focuses on matching equivalence classes of representations rather than exact features. This approach posits that a student model should learn the teacher's representation equivalence class, which is invariant to orthogonal and isotropic scaling, to effectively capture the teacher's capability. The framework unifies various distillation techniques, including feature matching, relational distillation, and alignment, by framing them within a geometric account. Experiments conducted with Qwen2.5 and Llama-3.1 models demonstrate the efficacy of this method, showing that while it can restore a corrupted model's representation, it does not necessarily restore its capability.
