Title:
SIGNAL ANALYSIS DEVICE, SIGNAL ANALYSIS METHOD, COMPUTER PROGRAM, MEASUREMENT DEVICE, AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/042752
Kind Code:
A1
Abstract:
Provided are a signal analysis device, signal analysis method, computer program, measurement device, and measurement method for carrying out cluster analysis so as to make it possible to acquire a distribution that has conventionally been difficult to acquire from a spectral distribution. In the present invention, a signal analysis device generates n-dimensional coordinate points defined through the combination of the intensities of n specific signals included in a spectrum; determines a plurality of initial cluster values on an n-dimensional space for the purpose of classifying the plurality of n-dimensional coordinate points; and carries out analysis using the determined initial cluster values. When determining the initial cluster values, the signal analysis device generates an initial cluster value that includes a point on the n-dimensional space that consists of a combination of the representative values for the intensities of the n specific signals and generates initial cluster values that each include an n-dimensional coordinate point where the intensity of one specific signal has deviated from a prescribed standard.
