Published: March 8, 2025

Abstract The rapid increase in global waste production, particularly Polymer wastes, poses significant environmental challenges because of its nonbiodegradable nature and harmful effects on both vegetation aquatic life. To address this issue, innovative construction approaches have emerged, such as repurposing Polymers into building materials. This study explores the development eco-friendly bricks incorporating cement, fly ash, M sand, polypropylene (PP) fibers derived from Polymers. primary innovation lies leveraging advanced machine learning techniques, namely, artificial neural networks (ANN), support vector machines (SVM), Random Forest AdaBoost to predict compressive strength these Polymer-infused bricks. polymer bricks’ was recorded output parameter, with PP waste, age serving input parameters. Machine models often function black boxes, thereby providing limited interpretability; however, our approach addresses limitation by employing SHapley Additive exPlanations (SHAP) interpretation method. enables us explain influence different variables predicted outcomes, thus making more transparent explainable. performance each model evaluated rigorously using various metrics, including Taylor diagrams accuracy matrices. Among compared models, ANN RF demonstrated superior which is close agreement experimental results. achieves R 2 values 0.99674 0.99576 training testing respectively, whereas RMSE value 0.0151 (Training) 0.01915 (Testing). underscores reliability estimating strength. Age, ash were found be most important variable predicting determined through SHAP analysis. not only highlights potential enhance predictive for sustainable materials demonstrates a novel application improve interpretability context repurposing.

Machine Learning-Based Partition Method for Cyclic Development Mode of Submarine Soil Martials from Offshore Wind Farms

Journal of Marine Science and Engineering, Journal Year: 2025, Volume and Issue: 13(3), P. 533 - 533

Published: March 10, 2025

Offshore wind turbines are subjected to long-term cyclic loads, and the seabed materials surrounding foundation susceptible failure, which affects safe construction normal operation of offshore turbines. The existing studies mechanical properties submarine soils focus on accumulation strain liquefaction, few targeted conducted hysteresis loop under loads. Therefore, 78 representative soil samples from four farms tested in study, behaviors different confining pressures CSR investigated. experiments reveal two unique development modes specify critical five martials testing conductions. Based dynamic triaxial test results, machine learning-based partition models for mode were established, discrimination accuracy discussed. This study found that RF model has a better generalization ability higher than GBDT discriminating soil, achieved prediction 0.96 recall 0.95 dataset, provides an important theoretical basis technical support design

Soft-computing models for predicting plastic viscosity and interface yield stress of fresh concrete

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 28, 2025

Interface yield stress and plastic viscosity of fresh concrete significantly influences its pumping ability. The accurate determination these properties needs extensive testing on-site which results in time resource wastage. Thus, to speed up the process accurately determining properties, this study tends use four machine learning (ML) algorithms including Random Forest Regression (RFR), Gene Expression Programming (GEP), K-nearest Neighbor (KNN), Extreme Gradient Boosting (XGB) a statistical technique Multi Linear (MLR) develop predictive models for interface concrete. Out all employed algorithms, only GEP expressed output form an empirical equation. were developed using data from published literature having six input parameters cement, water, after mixing etc. two i.e., stress. performance was assessed several error metrices, k-fold validation, residual assessment comparison revealed that XGB is most algorithm predict (training [Formula: see text], text]) text]). To get increased insights into model prediction process, shapely individual conditional expectation analyses carried out on highlighted are influential estimate both In addition, graphical user has been made efficiently implement findings civil engineering industry.
