MATERIAL PROPERTY PREDICTION SYSTEM AND MATERIAL PROPERTY PREDICTION METHOD

WIPO Patent Application WO/2021/054026

A1

Provided is a method for improving the prediction accuracy of material properties, by effectively utilizing past data.　The present invention is a system for predicting material properties, by processing project data including a plurality of records consisting of material compositions, experimental conditions, and material properties. This system comprises: a material property prediction presentation unit; an inter-project feature amount generation unit; and a material property prediction unit. The material property prediction presentation unit includes a record in which the material property is unknown, and receives the designation of first project data to be predicted for material properties by a first prediction model. The inter-project feature amount generation unit predicts the feature amount, from the material composition of the first project data, by using a second prediction model. The material property prediction unit generates the first prediction model, by using the material compositions, experimental conditions, feature amounts, and known material properties of the first project data. Further, the material property prediction unit predicts the unknown material property, by inputting the material compositions, the experimental conditions, and the feature amounts of the record in which the material property of the first project data is unknown.
