Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: A method of updating a neural network may be provided. A method may include computing gradients for an operating matrix of a current layer of the neural network based on data of at least one of the current layer and at least other layer of the neural network. The method may also include updating the operating matrix based on the computed gradients. Further, the method may include updating an indexing matrix of the current layer based on the updated operating matrix.
