Calculation method and device applied to neural networks

Abstract

The invention provides a calculation method and device applied to neural networks. The calculation method comprises the following steps of: obtaining a binary convolutional kernel which only comprisesa numerical value 1 and a -1 weight; decomposing the binary convolution kernel into an initial convolution kernel and a feature convolutional kernel, wherein the initial convolution kernel and the feature convolution kernel are same as the binary convolution kernel in the aspect of dimensionality, the initial convolution kernel is a matrix formed by a weight with a numerical value of 1, and the feature convolution kernel is a matrix formed by a weight with a numerical value of -1 relative to the binary convolution kernel; and carrying out convolution calculation in a neural network on the basis of the initial convolution kernel and the feature convolution kernel. By utilizing the calculation method and device provided by the invention, the convolution calculation efficiency can be improved and the storage circuit overhead can be saved.
