Explainable machine learning-based fractional vegetation cover inversion and performance optimization – A case study of an alpine grassland on the Qinghai-Tibet Plateau

Ecological Informatics, Journal Year: 2024, Volume and Issue: 82, P. 102768 - 102768

Fractional Vegetation Cover (FVC) serves as a crucial indicator in ecological sustainability and climate change monitoring. While machine learning is the primary method for FVC inversion, there are still certain shortcomings feature selection, hyperparameter tuning, underlying surface heterogeneity, explainability. Addressing these challenges, this study leveraged extensive field data from Qinghai-Tibet Plateau. Initially, selection algorithm combining genetic algorithms XGBoost was proposed. This integrated with Optuna tuning method, forming GA-OP combination to optimize learning. Furthermore, comparative analyses of various models inversion alpine grassland were conducted, followed by an investigation into impact heterogeneity on performance using NDVI Coefficient Variation (NDVI-CV). Lastly, SHAP (Shapley Additive exPlanations) employed both global local interpretations optimal model. The results indicated that: (1) exhibited favorable terms computational cost accuracy, demonstrating significant potential tuning. (2) Stacking model achieved among seven (R2 = 0.867, RMSE 0.12, RPD 2.552, BIAS −0.0005, VAR 0.014), ranking follows: > CatBoost LightGBM RFR KNN SVR. (3) NDVI-CV enhanced result reliability excluding highly heterogeneous regions that tended be either overestimated or underestimated.

A model for predicting slope stability is developed using Categorical Boosting (CatBoost), which incorporates 6 features to characterize the state of stability. The trained a symmetric tree as base model, utilizing ordered boosting replace gradient estimation, enhances prediction accuracy. Comparative models including Support Vector Machine (SVM), Light Gradient (LGBM), Random Forest (RF), and Logistic Regression (LR) were introduced. Five performance evaluation metrics are utilized assess predictive capabilities CatBoost model. Based on predicted probability instability calculated, early warning further established. results suggest that demonstrates 6.25% disparity in accuracy between training testing sets, achieving precision 100% an Area Under Curve (AUC) value 0.95. This indicates high level robust ordering capabilities, effectively mitigating problem overfitting. offers reasonable classifications levels, providing valuable insights both research practical applications warning.

Hybrid Quantum Neural Network Model with Catalyst Experimental Validation: Application for the Dry Reforming of Methane

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(10), P. 4121 - 4131

Published: Feb. 23, 2024

Machine learning (ML), which has been increasingly applied to complex problems such as catalyst development, encounters challenges in data collection and structuring. Quantum neural networks (QNNs) outperform classical ML models, artificial (ANNs), prediction accuracy, even with limited data. However, QNNs have available qubits. To address this issue, we introduce a hybrid QNN model, combining parametrized quantum circuit an ANN structure. We used the sets of dry reforming methane reaction from literature in-house experimental results compare models. The exhibited superior accuracy faster convergence rate, achieving R2 0.942 at 2478 epochs, whereas achieved 0.935 3175 epochs. For 224 points previously unreported literature, enhanced generalization performance. It showed mean absolute error (MAE) 13.42, compared MAE 27.40 for under similar training conditions. This study highlights potential powerful tool solving catalysis chemistry, demonstrating its advantages over
