Noise estimation method, noise estimation program and noise estimation device

摘要

Problem to be solved.The decomposing Part 13 decomposes the first matrix whose value of the element is binary, into the coefficient matrix and the base matrix.The inference part 14 estimates the element including the noise among the elements of the first matrix based on the result obtained by comparing the second matrix combining the coefficient matrix and the base matrix with the first matrix.Further, the removing unit 15 removes the estimated error from the binary matrix.The analyzing section 17 analyzes data based on a binary matrix whose noise has been removed.Diagram
