Abstract
An apparatus includes: a degradation pattern generation unit for generating a degradation pattern indicating distributions of signal intensities of measured signals and a phase of an alternating voltage; a histogram calculation unit for calculating a gradient vector of a signal density at each of distribution points of the degradation pattern, and calculating, for each of phase ranges different from each other, from the calculated gradient vector, a histogram in a gradient direction of the signal density within the relevant phase range; a feature vector generation unit for generating a feature vector in which bin values of the histogram for each of the phase ranges are lined up; and a degradation cause identification unit for searching for, from among feature vectors by degradation cause, a feature vector similar to the feature vector generated by the feature vector generation unit, and outputting a degradation cause related to the similar feature vector.
