Ultra-high-performance concrete (UHPC) is a cutting-edge and advanced constructions material known for its exceptional mechanical properties durability. Recently, machine learning (ML) methods play pivotal role in predicting the compressive strength (CS) of UHPC evaluating dominant input parameters suitable mix design. This research, three hybrid models were utilized: Random Forest (RF), AdaBoost (AB), Gradient Boosting (GB) algorithms with particle swarm optimization (PSO), namely AB-PSO, RF-PSO, GB-PSO, to predict perform SHAP (Shapley additive explanation) analysis. To build predictive ML models, dataset 810 experimental data points was collected from published literature. Additionally, interaction plots generated visualize impact each feature on specific prediction made by model. Our results indicate that better than traditional GB-PSO model showed high accuracy among models. The had higher precision compared other two It achieved R2 values 0.9913 during training stage 0.9804 testing CS. analysis revealed age, fiber, cement, silica fume, superplasticizer significant influence strength, while comparatively lower. PDP (Partial Dependence Plots) amount individually variables can be calculated simply designed These findings are valuable construction applications offer essential insights design engineers builders, aiding their understanding significance component UHPC.

Ultra-high-performance concrete (UHPC) is a sustainable construction material; it can be applied as substitute for cement concrete. Artificial intelligence methods have been used to evaluate composites reduce time and money in the industries. So, this study machine learning (ML) hybrid ML approaches predict compressive flexural strength of UHPC. A dataset 626 317 data points was collected from published research articles, where fourteen important variables were selected input parameters analysis algorithms. This XGBoost, LightGBM, XGBoost- LightGBM algorithms UHPC materials. Grid search (GS) techniques adjust model hyper-parameters improved high accuracy efficiency. models train, test stage utilized statistical assessments such R-square, root mean square error (RMSE), absolute (MAE), coefficient efficiency (CE).

Accurately predicting key features in WWTPs is essential for optimizing plant performance and minimizing operational costs. This study assesses the potential of various machine learning models inflow to anoxic sludge reactors. Firstly, it conducts a comprehensive evaluation diverse models, including k-Nearest Neighbors (kNN), Random Forest (RF), XGBoost, CatBoost, LightGBM, Decision Tree Regression (DTR), flow into Anoxic section under weather conditions (dry, rainy, stormy). Secondly, introduces parsimonious guided by variable importance from XGBoost algorithm. Furthermore, employs SHAP (SHapley Additive exPlanations) elucidate model predictions, providing insights contribution each feature. Data COST Benchmark Simulation Model (BSM1) used verify investigated models' effectiveness. Each dataset consists 14 days influent data at 15-minute intervals, with 80% training. Results show that ensemble methods, particularly CatBoost demonstrate satisfactory predictive results presence increased variability rainy stormy conditions. Notably, achieve average Mean Absolute Percentage Error values 1.33% 1.59%, outperforming other methods.

This study addresses a critical gap in human activity recognition (HAR) research by enhancing both the explainability and efficiency of classification collaborative human–robot systems, particularly agricultural environments. While traditional HAR models often prioritize improving overall accuracy, they typically lack transparency how sensor data contribute to decision-making. To fill this gap, integrates explainable artificial intelligence, specifically SHapley Additive exPlanations (SHAP), thus interpretability model. Data were collected from 20 participants who wore five inertial measurement units (IMUs) at various body positions while performing material handling tasks involving an unmanned ground vehicle field harvesting scenario. The results highlight central role torso-mounted sensors, lumbar region, cervix, chest, capturing core movements, wrist sensors provided useful complementary information, especially for load-related activities. XGBoost-based model, selected mainly allowing in-depth analysis feature contributions considerably reducing complexity calculations, demonstrated strong performance HAR. findings indicate that future should focus on enlarging dataset, investigating use additional placements, real-world trials enhance model’s generalizability adaptability practical applications.
