Abstract
This paper presents a novel ensemble learning framework that integrates Adaptive Boosting Regression Threshold (AdaBoost.RT) with weighted extreme learning machines (WELMs) to improve seismic performance in intelligent control systems. In our approach, the Imperialist Competitive Algorithm (ICA) is used to optimize the relative error threshold of AdaBoost.RT, and WELMs are selected as base predictors due to their fast-training times and robustness in handling nonlinear phenomena. The proposed framework incorporates sample weights into the output weights of the ELMs and updates them iteratively, effectively capturing complex dynamic behaviors, including those arising from soil–structure interaction (SSI) under stochastic excitations. Comparative analyses with established ensemble learning techniques demonstrate that the presented optimized, fast, and efficient model achieves superior predictive accuracy, generalization capabilities, and computational efficiency. The methodology is validated through extensive simulations and experimental data, showcasing its potential for addressing smart control challenges in engineering applications. This research not only advances the state of the art in ensemble learning for active control systems but also contributes to the broader field of nonlinear dynamics by providing a reliable, efficient, and robust tool for system identification and vibration control in oscillating systems.
Purpose. This research aims to provide a physics-based ensemble machine learning framework that can reliably predict slope stability and distinguish stable from unstable slopes in static and seismic conditions. Standard analytical and numerical methods have significant processing costs and oversimplified assumptions that limit their usefulness.
Methods. The study analyzed 700 slope stability samples, including geotechnical and seismic factors such as slope height, slope angle, cohesion, internal friction angle, and peak ground acceleration. The proposed model now includes physics-based engineering elements, such as tan ϕ, c/H, and PGA/g, to account for geotechnical interactions. A linear meta-learner and Random Forest and Gradient Boosting regressors were used to develop a stacked ensemble framework. We assessed model strength and reliability.
Findings. The devised framework showcased exceptional prediction performance with an (R2) of 0.982, a mean absolute error of 0.02 and a root mean square error of nearly 0.03. Cross-validation showed consistent generalization. Random Forests classified slope stability conditions with 97.4% accuracy. The most important parameters for slope stability predictions were the internal friction angle and cohesiveness. Furthermore, the inclusion of carefully crafted physics-based features demonstrably improved robustness, accuracy and consistency.
Originality. This work introduces a pioneering, combined framework that fuses the mechanics of geotechnical soil with ensemble machine learning techniques, enhancing both interpretability and the certainty of slope stability predictions.
Practical implications. The framework may support rapid, cost-effective, and interpretable preliminary geotechnical risk assessment and design screening. However, its use in slope monitoring or early-warning applications requires further field validation and integration with monitoring data.

This study presents three advanced machine learning models: the evolutionary Gaussian process inference model, the artificial satellite search algorithm–moment balance machine (ASSA-MBM), and the Operation Rain Forest (ORF), which are designed to predict the maximum reinforcement load in geosynthetic-reinforced soil structures. These models were developed to enhance both predictive accuracy and model interpretability by incorporating state-of-the-art optimization algorithms and explainable machine learning frameworks. A comprehensive evaluation was conducted using 10-fold cross-validation, and the proposed models were benchmarked against previously developed AI models from literature, as well as traditional and semiempirical approaches such as Rankine, Coulomb, and
