Abstract
An information processing apparatus that performs deep learning using a neural network includes a memory, and an arithmetic processing device that performs a process for layers of the neural network in a predetermined direction. The process for the layers includes: pre-determining a decimal point position of a fixed-point number of an intermediate data obtained by an operation of each of the layers; performing the arithmetic operation for each layer with the pre-determined decimal point position to obtain the intermediate data and acquiring first statistical information of a distribution of bits of the intermediate data; determining a decimal point position of the intermediate data based on the statistical information; and performing the arithmetic operation for each layer with the determined decimal point position again when the difference of the determined decimal point position and the pre-determined decimal point position is greater than a threshold value.
