Improving Generalization by Self-Training Self Distillation

This might sound strange as such a supervised self-training process (aka self-distillation) does not receive any new information about the task and solely evolves by retraining itself. In this talk, I argue such self-training process induces additional regularization, which gets amplified in each round of retraining.
