Title:

CONVOLUTIONAL LAYER CONVERSION DEVICE, CONVOLUTIONAL LAYER CONVERSION METHOD, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2023/139680

Kind Code:

A1

Abstract:

The present invention provides a convolutional layer conversion device that contributes to an increase in execution speed when implementing a convolutional layer of a neural network model. The convolutional layer conversion device comprises: a convolutional layer detection unit that, from a neural network model structure which has been input, detects a convolutional layer containing a large kernel which has a kernel size greater than or equal to a prescribed size; and a convolutional layer breakdown unit that converts a convolutional layer into a convolutional layer which includes a combination of a plurality of small kernels obtained by breaking down a detected large kernel into a plurality of small kernels having a kernel size smaller than the prescribed size, and an integration convolutional layer which integrates the result of the convolutional layer including a plurality of small kernels, and that outputs a neural network model structure in which the convolutional layer has been converted.
