SPECTROMÈTRE DE MASSE, PROCÉDÉ ET PROGRAMME DE SPECTROMÉTRIE DE MASSE POUR DISCRIMINER UNE SOUCHE DANS UN MICROORGANISME

摘要

Each of a plurality of mass spectral data that includes a microorganism of which strain is known is acquired as training data by a training data acquirer. A sample corresponding to each training data includes an additive, and a matrix is mixed with the sample. A discrimination analysis model for discriminating a strain based on the acquired plurality of training data is produced by a model producer by performing machine learning. Mass spectral data that includes a microorganism of which strain is unknown is acquired as target data by a target data acquirer. A sample corresponding to the target data includes the additive, and the matrix is mixed with the sample. A strain of the microorganism corresponding to the acquired target data is discriminated by a discriminator based on the produced discrimination analysis model for each strain and the acquired target data.
