Abstract: A neural network system includes a separable convolution subnetwork. The separable convolution subnetwork includes a plurality of separable convolutional neural network (SCNN) layers arranged in a stack manner in sequence. Each of the plurality of SCNN layers applies a first grouped convolution to an input to the SCNN layer. An input to the first grouped convolution includes a plurality of channels, and the first grouped convolution is a spatial convolution which divides channels of an input to the first grouped convolution into groups in a channel-wise manner, convolves the grouped channels, and couples the convolved channels to generate an output.
