Basalt fibers are a type of reinforcing fiber that can be added to concrete improve its strength, durability, resistance cracking, and overall performance. The addition basalt with high tensile strength has particularly favorable impact on the splitting concrete. current study presents data set experimental results tests curated from literature. Some best-performing ensemble learning techniques such as Extreme Gradient Boosting (XGBoost), Light Machine (LightGBM), Random Forest, Categorical (CatBoost) have been applied prediction reinforced fibers. State-of-the-art performance metrics root mean squared error, absolute error coefficient determination used for measuring accuracy prediction. each input feature model visualized using Shapley Additive Explanations (SHAP) algorithm individual conditional expectation (ICE) plots. A greater than 0.9 could achieved by XGBoost in strength.

Improved forecasting of the compressive strength of ultra‐high‐performance concrete (UHPC) via the CatBoost model optimized with different algorithms

Structural Concrete, Journal Year: 2024, Volume and Issue: unknown

Published: May 19, 2024

Abstract This paper focuses on the applicability of CatBoost models constructed using various optimization techniques for improved forecasting compressive strength ultra‐high‐performance concrete (UHPC). Phasor particle swarm (PPSO), dwarf mongoose (DMO), and atom search (ASO), which have been very popular recently, are preferred as algorithms. A comprehensive reliable data set is used to develop models, include 785 test results with 15 input features. The performance (PPSO‐CatBoost, DMO‐CatBoost, ASO‐CatBoost) optimized different algorithms thoroughly assessed by means statistical metrics error analysis determine model best capability, this compared obtained from previous studies. In addition, Shapley additive exPlanations (SHAP) ensure interpretability overcome “black box” problem machine learning (ML) models. demonstrate that all outstandingly forecast UHPC. Among these DMO‐CatBoost stands out other in metrics, such high coefficient determination ( R 2 ) values, low root mean squared (RMSE), absolute percentage (MAPE), (MAE) along a smaller ratio. words, RMSE, , MAPE, MAE values training 3.67, 0.993, 0.019, 2.35, respectively, whereas those 6.15, 0.978, 0.038, 4.51. Additionally, ranking optimize hyperparameters follows: DMO > PPSO ASO. On hand, SHAP showed age, fiber dosage, cement dosage significantly influence These findings can guide structural engineers design UHPC, thus assisting them developing strategies improve properties material. Finally, based developed work, graphical user interface has easily UHPC practical applications without additional tools or software.
