Abstract
An arithmetic processing apparatus includes: a memory that stores, when a training of a given machine learning model is repeatedly performed in a plurality of iterations, an error of a decimal point position of each of a plurality of fixed-point number data obtained one in each of the plurality of iterations, the error being obtained based on statistical information related to a distribution of leftmost set bit positions for positive number and leftmost unset bit positions for negative number or a distribution of rightmost set bit positions of the plurality of fixed-point number data; and a processor coupled to the memory, the processor being configured to: determine, based on a tendency of the error in each of the plurality of iterations, an offset amount for correcting a decimal point position of fixed-point number data used in the training.
