COMPRESSING A NEURAL NETWORK

A computer implemented method of compressing a neural network, the method comprising:receiving a neural network comprising a plurality of layers; forming a graph that represents the flow of data through the plurality layers of the neural network, the graph comprising: a plurality of vertices, each vertex of the plurality of vertices being representative of an output channel of a layer of the plurality of layers of the neural network; and one or more edges, each edge of the one ormore edges representing the potential flow of non-zero data between respective output channels represented by a respective pair of vertices; identifying, by traversing the graph, one or more redundant channels comprised by the plurality of layers of the neural network; and outputting a compressed neural network in which the identified one or more redundant channels are not present in the compressed neural network.
