Abstract
Included in an inference device of a neural network are: a memory for storing a layer on an input side and weight data for generating a matrix multiplication using the layer on the input side; and a processor for generating a layer on an output side, by using the layer on the input side and the weight data for generating the matrix multiplication using the layer on the input side, in which, out of a plurality of rows and columns including zero elements and non-zero elements in the weight data, the memory stores only non-zero weights and position information of the non-zero weights and the number of non-zero elements in each of the rows is approximately the same. Therefore, it is possible to reduce the amount of memory in a memory for storing learned weight data of a weight matrix. It is also possible to reduce the amount of memory of a memory for storing positions of non-zero weight elements of the weight matrix.
