Robust Ensemble Framework
Our methodology meticulously constructs and optimizes hybrid ensemble models, combining the strengths of various machine learning techniques. We employed boosting (XGBoost, Gradient Boosting, LightGBM, CatBoost, AdaBoost), bagging (Decision Tree, Bagged Decision Tree, Random Forest, Extra Trees, Bagging Meta-Estimator), stacking, and voting. This multi-phase approach ensures high accuracy and generalizability, rigorously validated through k-fold cross-validation and statistical tests. Furthermore, we integrated SHAP and LIME for unparalleled model interpretability.

Explainable AI for Actionable Insights
Integrating SHAP and LIME analyses provides critical transparency. SHAP identified weight, height, age, gender, food habits, and alcohol consumption as key predictors, aligning with clinical understanding. LIME offers local, instance-based explanations, revealing how specific factors influence individual predictions. For example, a LIME analysis for a patient predicted 'overweight level II' (67% confidence), influenced significantly by weight (WT ≤ 107.43), fruit/vegetable consumption (FV ≤ 2.00), and age (AG ≥ 22.78). This empowers clinicians with personalized intervention strategies.
Case Study: Individualized Risk Profile (LIME Analysis)
Our LIME analysis of a specific patient instance demonstrates how individual lifestyle factors contribute to the model's prediction. For this patient, the model predicted an 'Overweight Level II' obesity class with 67% confidence. Key contributing features identified by LIME include:
- Weight (WT ≤ 107.43): Significant positive influence towards higher obesity levels.
- Fruit & Vegetable Consumption (FV ≤ 2.00): Lower intake pushed the prediction towards obesity.
- Age (AG ≥ 22.78): Older age was a factor in the classification.
- Gender (GD ≤ 1.00): Male gender contributed to the prediction.
This level of detail enables clinicians to offer highly personalized advice, such as dietary adjustments and increased physical activity, targeting the most influential factors for that individual.
