SqueezeNet-Deep-Compression
This is the 660KB compressed SqueezeNet, which is 363x smaller as AlexNet but has the same accuracy as AlexNet.
(There is an even smaller version which is only 470KB. It requires some effort to materialize since each weight is 6-bits.)
Usage
export CAFFE_ROOT=$your_caffe_root
python decode.py /ABSOLUTE_PATH_TO/SqueezeNet_deploy.prototxt /ABSOLUTE_PATH_TO/compressed_SqueezeNet.net /ABSOLUTE_PATH_TO/decompressed_SqueezeNet.caffemodel
note: decompressed_SqueezeNet.caffemodel is the output, can be any name.
$CAFFE_ROOT/build/tools/caffe test --model=SqueezeNet_trainval.prototxt --weights=decompressed_SqueezeNet.caffemodel --iterations=1000 --gpu 0
