Improving diabetes diagnosis using metaheuristic-based ensemble classification method
This paper introduces a novel hybrid framework for diabetes diagnosis, integrating advanced data mining techniques. By combining BSMOTE with GPC for synthetic sample generation, k-NN for missing data imputation, and an ensemble of k-NN, SVM, RF, and ELM classifiers with majority voting, the framework achieves significantly improved prediction accuracy (91%-93.9%) on the PIMA Indian Diabetes Dataset. This represents up to a 6% improvement over existing methods, effectively addressing data imbalance, missing values, and enhancing early diabetes diagnosis and management.

Data Preprocessing
- K-Nearest Neighbors (k-NN) for missing data imputation using Euclidean distance.
- Quartile-based method for outlier detection and removal.
- Hybrid Borderline SMOTE (BSMOTE) with Giza Pyramids Construction (GPC) for synthetic minority sample generation, addressing data imbalance.
Ensemble Classification
- Integration of four base classifiers: k-NN, SVM, Random Forest (RF), and Extreme Learning Machine (ELM).
- Majority voting scheme to combine predictions for final classification.
- Hyperparameter optimization for each classifier (k-NN: k=15 Euclidean; SVM: RBF kernel, C=10; RF: ntrees=100, dmax=20; ELM: 200 hidden neurons, Sigmoid activation).
Performance Evaluation
- Evaluated on PIMA Indian Diabetes Dataset, BRFSS, and MIMIC-III.
- Metrics: Accuracy, Precision, Recall, F1-score, False Negative Rate (FNR), False Positive Rate (FPR).
- Achieved 91%-93.9% accuracy, up to 6% improvement over existing methods.
- Demonstrated scalability and robustness on large-scale datasets with noisy/incomplete data.
