Learning apparatus, operation method of learning apparatus, operation program of learning apparatus, and operating apparatus

An operation method of a learning apparatus, the method comprising:

• acquiring multi-dimensional physical-property data representing a physical property of a product;
• deriving learning input data to be input to a machine learning model for predicting a quality of the product from the multi-dimensional physical-property data and deriving, as the learning input data, multi-dimensional physical-property relevance data which is related to the multi-dimensional physical-property data by applying at least a part of an autoencoder to the multi-dimensional physical-property data;
• and
• inputting the learning input data to the machine learning model, performing learning, and outputting the machine learning model as a learned model to be provided for actual operation.

A non-transitory computer readable recording medium storing an operation program of a learning apparatus, the program causing a computer to function as:

• acquiring multi-dimensional physical-property data representing a physical property of a product;
• deriving learning input data to be input to a machine learning model for predicting a quality of the product from the multi-dimensional physical-property data and that derives, as the learning input data, multi-dimensional physical-property relevance data which is related to the multi-dimensional physical-property data by applying at least a part of an autoencoder to the multi-dimensional physical-property data;
• and
• inputting the learning input data to the machine learning model, performing learning, and outputting the machine learning model as a learned model to be provided for actual operation.
