In this paper. we propose an online ensemble distillation (OED) method to automatically prune blocks/layers of a target network by transferring the knowledge from a strong teacher in an end-to-end manner. To accomplish this. we first introduce a soft mask to scale the output of each block in the target network and enforce the sparsity of the mask by sparsity regularization. https://parisnaturalfoodes.shop/product-category/sport-protein-berry/
