Title: Training a neural network comprising a plurality of layers
Inventor: MUHAMMAD ASAD
IPC: G06N3/08
Filed: 2020-12-22
Abstract: A method of applying sparsity and channel pruning to a neural network, such as an image processing convolutional neural network. A neural network layer 200-2a combines a filter set 204-2a with input data 202-2a to form output data 206-2a. Each filter set comprises coefficient channels a-d which correspond to data channels A-D in the input data. The output data comprises data channels which correspond to the filters. The method begins by identifying a target coefficient channel and identifying a corresponding target data channel. The method continues by configuring a runtime implementation of the neural network in which the filter set 204-1a of a preceding layer 200-1a does not comprise the filter corresponding to the target data channel. The target coefficient channel may be identified according to a sparsity parameter which indicates a level of sparsity to be applied to the layer’s filters. The sparsity parameter may be determined by iteratively applying a sparsity algorithm to the filter set’s coefficient channels according to the sparsity parameter, operating a test neural network, and updating the sparsity parameter based on the test neural network’s accuracy. Determining the sparsity parameter may also include balancing the level of sparsity against the accuracy of the network.
