基于支持向量机的超早强混凝土抗压强度预测研究
Study of Compression Strength Prediction of Ultra High-early-strength Concrete by Support Vector Machine
摘要
Abstract
In recent years,the criterion of ultra high-early-strength concrete in project is increasingly stricter,not only the time requirement of reaching certain strength,but also requirements of maximum economic effectiveness.However,the predicting process would be complicated because of the various factors which can have impact on its strength.In this paper,SVM (support vector machine) will be used to build a numerical model that can predict its strength via comparing different kernel functions and parameters,and the most optimized kernel function can be obtained.In conclusion,numerical models with linear kernel function and RBF kernel function can lead to reasonable results,and the one with RBF kernel function is the best.关键词
