| Summary: | Title screen Precise prediction of water activity (WA) in ionic liquids (IL) systems is impeded by their complex, nonlinear interactions, and the limitations of traditional thermodynamic models. Machine learning offers an effective alternative for capturing complex property patterns and improving WA predictions. This study develops predictive models for WA using the multilayer extreme learning machine (MELM) and least squares support vector machine algorithms, as well as hybrid versions optimized with particle swarm optimization (PSO) and genetic algorithm, based on a large laboratory dataset. Following data cleaning, the feature selection analysis identified seven key parameters: temperature, pressure, molality of second composition, molality of IL, critical temperature of IL, acentric factor of IL, and critical pressure of IL. A portion of the training data was allocated as validation data using k-fold cross-validation, with the number of folds carefully selected to ensure optimal model performance and prevent overfitting. The results demonstrate that hybrid models in the prediction of the target variable, particularly MELM-PSO, exhibit superior reproducibility, lower error values across the training, validation, and testing phases, and reduced uncertainty and overfitting compared to other models. The proposed WA-prediction models can potentially be applied to various industrial sectors, including energy storage, gas purification, and process control Текстовый файл AM_Agreement |
