DSD Model Zoo
This repo contains pre-trained models by Dense-Sparse-Dense(DSD) training on Imagenet.
Compared to conventional training method, dense→sparse→dense (DSD) training yielded higher accuracy with same model architecture.
Sparsity is a powerful form of regularization. Our intuition is that, once the network arrives at a local minimum given the sparsity constraint, relaxing the constraint gives the network more freedom to escape the saddle point and arrive at a higher-accuracy local minimum.
Single-crop (224x224) validation error rate:
|Baseline||Top-1 error||Top-5 error||DSD||Top-1 error||Top-5 error|
