Deep Compression on AlexNet

This is a demo of Deep Compression compressing AlexNet from 233MB to 8.9MB without loss of accuracy. It only differs from the paper that Huffman coding is not applied. Deep Compression's video from ICLR'16 best paper award presentation is available.

Usage:

export CAFFE_ROOT=$your caffe root$

python decode.py bvlc_alexnet_deploy.prototxt AlexNet_compressed.net $CAFFE_ROOT/alexnet.caffemodel 

cd $CAFFE_ROOT

./build/tools/caffe test --model=models/bvlc_alexnet/train_val.prototxt --weights=alexnet.caffemodel --iterations=1000 --gpu 0

Test Result:
