Machine Learning Predicts Compressive and Flexural Strengths of Ultra-High-Performance Concrete
Researchers from Shahrood University of Technology have utilized machine learning methods to predict the compressive and flexural strengths of ultra-high-performance concrete (UHPC) with various fiber types. The study employed six machine learning algorithms, including gradient boosting, light gradient-boosting machine, and deep neural networks, to analyze a dataset of 321 and 863 experimental data points for flexural and compressive strength, respectively. The results indicated that the categorical gradient boosting (CatBoost) algorithm was the most effective predictor of the model for both compressive and flexural strength, with R2 values of 0.9309 and 0.9210 for the test data.
