PROBLEM TO BE SOLVED: To provide a signal source classification technique which is hardly affected by time-variant change of magnitude of a source signal.SOLUTION: A first matrix in which columns formed of samples of plural channels corresponding to respective time points in a predetermined time zone derived from time-series signals of observed plural channels, are respectively formed as respective elements of a column vector, is provided. Then, a second matrix which becomes the first matrix by multiplying the second matrix formed of non-negative value elements by a third matrix formed of non-negative value elements, is obtained. Then, a column vector of the second matrix is subjected to clustering. |
