DATA ANALYSIS METHOD, DATA ANALYSIS APPARATUS, AND RECORDING MEDIUM HAVING RECORDED PROGRAM

摘要

A data analysis method decomposes a fundamental matrix with N rows and M columns indicating relatedness with each of first N objects and each of second M objects into three matrices, and clusters at least the first objects or the second objects. The data analysis method includes acquiring the fundamental matrix having each element storing a value indicating the relatedness, setting K indicating a number of clusters of the first N objects and L indicating a number of clusters of the second M objects, decomposing the fundamental matrix into three matrices which are a first matrix, a second matrix, and a third matrix such that a product of the first matrix, the second matrix, and the third matrix approximates the fundamental matrix, and outputting at least one of clustering results of the first objects and the second objects.

1. A data analysis method that decomposes a fundamental matrix with N rows and M columns indicating relatedness with each of first N objects and each of second M objects into three matrices, and clusters at least the first objects or the second objects, the data analysis method comprising:
acquiring the fundamental matrix having each element storing a value indicating the relatedness; setting K indicating a number of clusters of the first N objects and L indicating a number of clusters of the second M objects; decomposing the fundamental matrix into three matrices which are a first matrix, a second matrix, and a third matrix such that a product of the first matrix, the second matrix, and the third matrix approximates the fundamental matrix, the first matrix having N rows and K columns, the second matrix having K rows and L columns with each element at least one of a particular row and a particular column thereof storing a value falling within a predetermined range, the third matrix having L rows and M columns; and outputting at least one of clustering results of the first N objects and the second M objects by outputting at least one of the first matrix, the second matrix, and the third matrix.
