Data processing device, data processing method, and data processing program

A data processing method in a data processing device that includes a neural network including convolution processing using a Winograd algorithm, the data processing method comprising:

• acquiring target data to be processed;
• and
• processing the target data using the neural network including the convolution processing,
• wherein the data processing device calculates a Hadamard product of a result of kernel transformation processing based on the Winograd algorithm and a kernel transformation matrix when performing the convolution processing, and obtains a result of the convolution processing by using a calculation result of the Hadamard product for multiplication, and
• wherein values of elements of the kernel transformation matrix are powers of 2 and have different constant values corresponding to divisors of division required for the kernel transformation processing when the kernel transformation matrix is not applied, and are set such that no division is included in the operation processing before the multiplication is executed.
