Supplementary material:

- cvpr18-supp.pdf: a longer version of the paper with proofs, pseudocode and
  extended experimental results.

- *.gif: GIF animations showing the evolution over iterations of the
  first-layer weights for Lenet300 on MNIST (95% weights pruned), displayed
  as a 28x28 image per hidden unit (red: negative, blue: positive, white:
  zero). Pruned units (having no in- or out-connections) are marked as gray.

All these animations may be seen with a web browser or with specialized
GIF image viewers. For example, in Linux:
  gifview animation.gif
  animate -delay 100 -resize 1200x900 animation.gif
  smplayer animation.gif
