Prediction model generation method, metal material corrosion amount prediction method, prediction model generation program, and prediction model generation device

摘要

PROBLEM TO BE SOLVED: To provide a prediction model generation method, a metal material corrosion amount prediction method, a prediction model generation program and a prediction model, which have high prediction accuracy and can easily interpret the prediction result by unifying the magnitude of influence. To provide a generator. SOLUTION: A prediction model generation method is a method of searching for an influence degree of an explanatory variable on a prediction variable for each explanatory variable, and a similarity between the explanatory variable to be predicted and the explanatory variable of past actual data. The impact search process includes a similarity calculation step that calculates using the degree of influence and a model generation step that generates a regression model using the similarity, so that the prediction accuracy of the regression model is high. Search for degrees. [Selection diagram] Figure 2
