«SSL» re-implements the paper Learning Structured Sparsity in Deep Neural Networks

In addition to the different pruning positions mentioned in the paper (filter_wise/channel_wise/filter_and_channel_wise/depth_wise), the warehouse also tried different weight functions (group_lasso/mean_abs/mean/sum_abs/sum).

Background

Based on Group Lasso, SSL can achieve Filter/Channel/Filter Shape/Depth pruning.

Installation

$ pip install -r requirements.txt

Usage

First, you need set env for PYTHONPATH and CUDA_VISIBLE_DEVICES

$ export PYTHONPATH=<project root path>
$ export CUDA_VISIBLE_DEVICES=0

Then, begin train-prune-finetuning

• For train

$ python tools/train.py -cfg=configs/vggnet/vgg16_bn_cifar100_224_e100_sgd_mslr_ssl_filter_wise_1e_5.yaml

• For prune

$ python tools/prune/prune_vggnet.py

• For fine-tuning

$ python tools/train.py -cfg=configs/vggnet/refine_mean_abs_0_2_vgg16_bn_cifar100_224_e100_sgd_mslr_ssl_filter_wise_1e_5.yaml

Finally, set the fine-tuning model path in the PRELOADED option of the configuration file

$ python tools/test.py -cfg=configs/vggnet/refine_mean_abs_0_2_vgg16_bn_cifar100_224_e100_sgd_mslr_ssl_filter_wise_1e_5.yaml
