Title:
PHYSICAL PROPERTY VALUE PREDICTION METHOD AND PHYSICAL PROPERTY VALUE PREDICTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/120057
Kind Code:
A1
Abstract:
According to the present invention, a physical property value prediction method involves inputting a plurality of images for prediction that have known measured values for a physical property value into a prediction model 21 that has been trained by machine learning, outputting a prediction value and a feature quantity map for each of the plurality of images for prediction, using the prediction results for images that have similar measured physical property values from among the plurality of images for prediction to specify a bad prediction image G3 for which the error between measured value and prediction value is at or above a first threshold value and a good prediction image G4 for which the error between measured value and prediction value is at or below a second threshold value that is smaller than the first threshold value, and extracting a feature quantity group that represents factors for bad prediction on the basis of the difference between the frequency distribution of the plurality of feature quantities that constitute the feature quantity map for the bad prediction image G3 and the frequency distribution of the plurality of feature quantities that constitute the feature quantity map for the good prediction image G4.
