Detecting device, detecting method, machine learning device, machine learning method, and machine learning model

A detecting method executed by a computer,

• the computer including a second machine learning model provided for mutual learning together with a first machine learning model, the first machine learning model being subjected to machine learning so as to generate genuine or fraudulent article information having a plurality of modalities, and the second machine learning model being subjected to machine learning so as to discriminate whether article information having a plurality of modalities is genuine or not,
• the detecting method comprising:
• obtaining article information having a plurality of modalities;
• and
• estimating whether the obtained article information having the plurality of modalities is genuine or not, by using the second machine learning model.

A computer readable and non-transitory recording medium which stores a detecting program for a computer,

• the computer storing a second machine learning model provided for mutual learning together with a first machine learning model, the first machine learning model being subjected to machine learning so as to generate genuine or fraudulent article information having a plurality of modalities, and the second machine learning model being subjected to machine learning so as to discriminate whether article information having a plurality of modalities is genuine or not,
• when the detecting program is executed by the computer, the program causing the computer to function as:
• an obtaining section configured to obtain article information having a plurality of modalities;
• and
• an estimating section configured to estimate whether the article information that is obtained by the obtaining section and has the plurality of modalities is genuine or not, by using the second machine learning model.
