TENSOR DATA CALCULATION DEVICE, TENSOR DATA CALCULATION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To speed up a process for super-tensor factorization, and to reduce a memory amount needed at the time of processing.;SOLUTION: Provided is a tensor data calculation device for performing, on N-dimensional tensor data (N is an integer greater than or equal to 3), a loop calculation for a plurality of indices to the tensor data, wherein the tensor data calculation device comprises: data placement processing means for executing the processes of sequencing the elements of tensor data in order from the lowest index of a calculation loop to each index immediately preceding the highest so that the loop direction of each index is forward, placing the values of non-empty elements in the tensor data and the index values of the lowest index indicating the position of the tensor data of the elements to an index immediately preceding the highest in a data storage unit, and placing the count value of the non-empty elements; and calculation processing means for performing a loop calculation on the tensor data placed in the data storage unit.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2016,JPO&INPIT
