Advanced Stacking Ensemble Learning
Our framework leverages a sophisticated stacking ensemble model, integrating the predictive strengths of Random Forest, Support Vector Machine, and CatBoost as foundational base learners. These are combined with a Multilayer Perceptron (MLP) as the meta-learner, which captures complex, non-linear relationships between base model outputs. This architecture significantly enhances predictive accuracy and robustness, outperforming individual classifiers and traditional ensemble methods by learning from diverse model perspectives and mitigating their individual weaknesses. Hyperparameter tuning using GridSearchCV ensures optimal performance and generalization.
Robust Data Preprocessing & SHAP Analysis
Effective data preparation is crucial for AI model performance. Our approach includes meticulous handling of class imbalance using SMOTE to generate synthetic minority samples, preventing bias towards the majority class. Categorical features are encoded with OneHotEncoder, and numerical variables are standardized via StandardScaler, ensuring data consistency. Crucially, SHAP (SHapley Additive exPlanations) analysis provides transparent insights into feature importance, confirming the clinical relevance of variables like ST_Slope, Cholesterol, and ExerciseAngina, fostering trust and interpretability in clinical decision-making.
Superior Predictive Performance & Generalization
The proposed MLP-based stacking model achieves an outstanding 97.06% accuracy, a recall of 96.08%, and a precision of 98%, significantly surpassing existing state-of-the-art models. Extensive K-fold cross-validation (K=10) ensures robust and unbiased performance assessment, demonstrating strong generalization capabilities and mitigating overfitting. The near-perfect Area Under the Receiver Operating Characteristic (AUC) of 1.00 and a flat Precision-Recall (PR) curve further affirm the model's exceptional ability to distinguish between healthy and diseased individuals, even in moderately imbalanced datasets, making it highly reliable for real-world clinical applications.
