Development of a stacked machine learning model to compute the capability of ZnO-based sensors for hydrogen detection by Behzad, Vaferi

“…This study proposes a stacked model by integrating Extra tree and XGBoost (eXtreme Gradient Boosting) regressor to precisely relate the sensitivity of the ZnO-based sensor to the nanocomposite's chemistry, H2 concentration, and temperature. The model's accuracy is superior to that of conventional artificial neural networks, achieving outstanding prediction results with mean absolute error (MAE) = 0.11, mean squared error (MSE) = 0.31, mean absolute percentage error (MAPE) = 1.14%, and R-squared (R2) = 0.9994 based on 208 actual sensor sensitivities. …”
