Can Students Outperform Teachers in Knowledge Distillation based Model Compression?

no code implementations1 Jan 2021 Xiang Deng, Zhongfei Zhang

By designing exploratory experiments, we find that model capacity differences are not necessarily the root reason, and the distillation data matters when the student capacity is greater than a threshold.
