Consistently Informative Soft-Label Temperature for Knowledge Distillation
The article discusses a new approach to knowledge distillation called Consistently Informative Soft-label Temperature (CIST). This method addresses the limitations of fixed-temperature designs by assigning adaptive temperatures to both teacher and student models. Empirical results show that CIST improves the consistency and effectiveness of knowledge transfer in machine learning tasks.
- ▪Knowledge distillation transfers knowledge from a teacher model to a student model using temperature scaling.
- ▪The standard fixed-temperature design can lead to inconsistent entropy in teacher soft labels.
- ▪CIST assigns separate sample-wise adaptive temperatures to improve the quality of teacher soft labels.

However, the standard fixed-temperature design is inherently sample-agnostic.
