Abstract
An information processing system according to the present invention is an information processing system that sets a weight matrix. The weight matrix is generated by learning using a target matrix that is a matrix including an action status on an item in each of a plurality of setting statuses as an element of a column, includes a weight corresponding to an intersection of items as an element, and is multiplied by the target matrix. The information processing system includes: a similarity degree calculating unit configured to extract, from each column of the target matrix, some elements from among all elements of the column, and calculate a degree of similarity between the items based on the some elements of the each column; and a weight matrix setting unit configured to set the weight matrix that is a sparse matrix including a nonzero element based on the degree of similarity.
