Abstract
A computation unit 11 performs, for each column of a target matrix to be standardized, a computation process to compute the average and standard deviation of the value of each component of the column. A first dividing unit 12 performs, for each column of the target matrix, a first dividing process to divide the value of each component of the column by the standard deviation computed based on the column. A second dividing unit 13 performs, for each column of the target matrix, a second dividing process to divide the average computed based on the column by the standard deviation computed based on the column. A generation unit 14 which arranges the quotients computed by a plurality of second dividing processes, in a row in the order of the columns of the target matrix from which the quotients are computed, thereby generating a row vector.
