DATA PROCESSING METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2021/083097

A1

A data processing method and apparatus, and a computer device and a storage medium. The method comprises: splitting a first convolution kernel according to a step length N to obtain a plurality of second convolution kernels (S11); splitting first input data according to the step length N to obtain a plurality of second input data corresponding to the plurality of first convolution kernels (S12); for any second input data, executing a Winograd convolution operation on the second input data and the corresponding second convolution kernel to obtain a convolution result corresponding to the second input data (S13); and determining that a sum of the convolution results corresponding to the plurality of second input data is a convolution result of the first convolution kernel and the first input data (S14). By means of the above method, the reusability of data can be improved.
