TRAINING DATA CREATION METHOD AND TRAINING DATA CREATION DEVICE

A method for creating learning data to be used for creating a discriminator that discriminates a plurality of target samples having attributes that differ from each other, the method including: acquiring measurement data of a plurality of reference samples having known attributes; extracting peak information using a first method for the measurement data of the reference samples; determining absence of a peak by collating the peak information extracted using the first method with peak information of a standard sample; extracting peak information using a second method that differs from the first method in an algorithm or/and a parameter for the measurement data of the reference samples, the measurement data being determined to have absence of a peak; determining absence of a peak by collating the peak information extracted using the second method with the peak information of the standard sample; and acquiring a feature amount from the measurement data determined to have no absence of a peak, to create learning data.
