The mechanical performance of these composites is primarily dictated by their interfacial properties [4], [5] . the determination of interfacial properties through fiber pullout tests involves labor-intensive and time-consuming experimental and numerical methods. Hence, there is a pressing need for an accurate and efficient alternative for predicting interfacial properties, essential for the design and  \ncustomization of composite materials.  \nIn recent years, machine learning (ML) techniques have emerged as promising substitutes for timeconsuming simulation processes that offer the advantage of low computational cost and high accuracy [6]–[10] . For instance, Mangalathu and Jeon [11] employed lasso regression for beam-column joints. Yao et al. [12] demonstrated the superiority of two-class support vector regression (SVR) over one-class SVR and logistic regression in mapping landslide susceptibility. Chopra et al. [13] investigated the efficiency of ML models such as decision trees (DT), random forests (RF), and neural networks in estimating concrete compressive strength. Their findings revealed the superior efficiency of the neural network model, followed by the RF method. Additionally, Das et al. [14] introduced a data-driven physics-informed approach for concrete crack estimation, showcasing the capability to predict infrastructure service life based on real-time monitoring data.  \nIn this study, the CatBoost algorithm is employed to predict the maximum force in fiber-reinforced composites. A grid search approach and K-fold crossvalidation are employed, utilizing a dataset comprising 922 samples to identify the optimum parameters of the ML model. Understanding why an ML model produces specific estimations and identifying the features influencing those estimations is crucial. Therefore, the Shapley additive explanations (SHAP) method is applied to comprehend the behavior of the ML model. The paper is organized as follows: Section 2 introduces SHAP as an interpretable ML approach; Section 3 presents a numerical example for maximum force prediction, and finally, Section 4 offers con","cbCaivXE9lKAiPhS","https://ap.wps.com/l/cbCaivXE9lKAiPhS","pdf",728754,1,"English","en",105,"# Introduction\n## Interpretable ML for maximum force prediction\n# Interpretable ML approach\n## SHAP methodology and feature attribution\n## Feature significance and error increase","[{\"question\":\"What model is used to predict the maximum force in fiber-reinforced composites?\",\"answer\":\"The study uses the CatBoost machine learning algorithm to predict maximum force from composite-related input variables.\"},{\"question\":\"How does SHAP improve interpretability in this research?\",\"answer\":\"SHAP provides a systematic way to measure the impact of individual input features on predictions, showing effects at both local and global scales.\"},{\"question\":\"What do the authors find about the relationship between feature importance and SHAP explanations?\",\"answer\":\"The feature importance analysis from CatBoost aligns with SHAP attributions, supporting the importance of certain parameters for predicting maximum force as an interfacial property.\"}]","Interpretable Machine Learning Approaches for Assessing Maximum Force in Fiber-Reinforced Composites -
