Researchers from King Khalid University and partner institutions apply AI-based regression models—including Multilayer Perceptron (MLP), Gaussian Process Regression (GPR), and Polynomial Regression (PR)—to computational fluid dynamics (CFD) datasets of adsorption processes. After preprocessing with a local outlier factor and gradient-based hyperparameter tuning, the MLP achieves superior predictive performance (R2=0.999, RMSE=0.583), demonstrating strong potential for environmental process optimization.
Key points
- MLP regression on CFD-derived adsorption data achieves R2=0.999 and RMSE=0.583, outperforming GPR and PR.
- Preprocessing uses Local Outlier Factor for data cleaning and Min-Max scaling for normalization.
- Gradient-based hyperparameter optimization and five-fold cross-validation validate MLP’s robustness (AARD%=2.56%).
Why it matters: This approach provides rapid, high-accuracy solute concentration predictions, enhancing adsorption-based water purification and resource-efficient environmental monitoring.
