An implementation of SqueezeNet in chainer.

Below are some benchmarks on a ImageNet-like dataset (1 million 255x255 images with 128 batch size)

Model Size (mb) Parameters (million) Accuracy
ZFNet 117 16.42 0.5835
SqueezeNet 4.6 1.288 0.5207


  • ZFNet instead of AlexNet (I already had a trained ZFNet model).
  • This is the basic squeezenet without deep compression. I had to add a dense layer to the end of SqueezeNet to get correct shape for my labels. I also had to add batch normalisation to the fire modules so it would fit.
  • The paper says images are 224x224 but the code and parameters suggests they use 227x227. I also added some padding, relu and initialisation that was used in the squeezenet code but not mentioned in the paper.
  • Accuracy of squeezenet is lower in this test but there is a 25x size reduction over ZFNet (SqueezeNet size is the same as in the paper) and a 12x reduction in params.
