Abstract: It is possible to perform factorization at high speed while maintaining consistency. Based on each of the plurality of tensors, a graph is constructed in which a plurality of factor matrices obtained by decomposing the tensors are set as vertices, and the vertices of factor matrices obtained by decomposing a same tensor are connected by edges. Assigning a number to each vertex of the graph is assigning the number so that the same number is not assigned to the other vertex connected by an edge. An order of updating the factor matrices is determined in a manner that factor matrices assigned a same number are set as a set of factor matrices to be subjected to parallel processing. Updating the factor matrices, based on the plurality of tensors, in the order of updating is repeatedly updating the set of factor matrices to be subjected to parallel processing in parallel.
