Use Case and High-Level Description

This is a classical classification network for 1000 classes trained on ImageNet. The difference is that most convolutional layers were replaced by binary once that can be implemented as XNOR+POPCOUN operations. Only input, final and shortcut layers were kept as FP32, all the rest convolutional layers are replaced by BinaryConvolution layers.

A blob with a BGR image in the format: [B, C=3, H=224, W=224], where:

  • B – batch size
  • C – number of channels
  • H – image height
  • W – image width

It is supposed that input is BGR in 0..255 range


The output is a blob with the shape [B, C=1000].
