pytorch-GENet

An unofficial Pytorch implementation of https://arxiv.org/abs/1810.12348. Probably.

The code replaces the standard blocks in a WideResNet with GEBlocks and trains these models on CIFAR-10/100. The blocks are defined in models/blocks.py

The code is currently untested, so ... see what happens when you run it.

Setup

Clean conda env as usual.

conda create -n prunes python=3.6
conda activate prunes
conda install pytorch torchvision -c pytorch

Running

All the various GE plus, minus, standards can be used by changing the following input arguments:

-extent: The extent factor. Set to 0 for global

-extra_params: Whether there are learnable parameters for downsampling

-mlp: Whether to use a squeeze-excite style MLP after downsampling

e.g. to train a WRN-16-8 with GE theta-minus blocks and global extent use:

python train.py --depth 16 --width 8 --extent 0  --extra_params False --mlp False

To train a WRN-16-8 with GE theta blocks and global extent, use:

python train.py --depth 16 --width 8 --extent 0  --extra_params True --mlp False

To train a WRN-16-8 with GE theta-plus blocks and extent 2, use:

python train.py --depth 16 --width 8 --extent 2  --extra_params True --mlp True

and so on, and so forth.
