Information processing device, information processing method, and non-transitory computer-readable storage medium for measured and unknown material

An information processing method of performing processing, by a processor, the processing comprising:

• setting respective spectral data measured from each of a plurality of materials as an instance of vector data;
• applying a dimension reduction technique to a plurality of instances of vector data so as to generate two-dimensional map data in which each of the plurality of instances of vector data is projected two-dimensionally as each of a plurality of plot points;
• identifying unknown data indicating a plot point that is different from a plot point present on the two-dimensional map data;
• converting the unknown data into converted spectral data;
• and
• outputting the converted spectral data,
• wherein the spectral data is data generated by performing frequency analysis of an image of a material, and
• wherein the process further comprises converting the unknown data into the converted spectral data, generating an image of an unmeasured material from the converted spectral data, and outputting the converted spectral data and the generated image of the unmeasured material.
