Title:
CEMENT QUALITY PREDICTION METHOD
Document Type and Number:
Japanese Patent JP2023056609
Kind Code:
A
Abstract:
To provide a method with which quality of cement can be predicted with high accuracy in a short time.SOLUTION: A cement quality prediction method is for predicting quality of cement by using a second prediction model created by using Lasso regression, and in the method, when the second prediction model is created, a tuning parameter α is defined by (A) a step of changing the numerical values of the tuning parameter α to create a plurality of first prediction models by using Lasso regression for every changed numerical value of the tuning parameter α, (B) a step of calculating a determination coefficient for each of the plurality of first prediction models by using a predicted value obtained by using the first prediction model and an actual measured value of output date for a test, and (C) a step of defining a tuning parameter α used for the creation of the first prediction model having the largest numerical value of the determination coefficient as a tuning parameter α used for the creation of the second prediction model.SELECTED DRAWING: Figure 1
