Enterprise AI Analysis
Optimizing high dimensional data classification with a hybrid AI driven feature selection framework and machine learning schema
Feature selection (FS) is critical for datasets with multiple variables and features, as it helps eliminate irrelevant elements, thereby improving classification accuracy. This study evaluated KNN, RF, MLP, LR, and SVM classifiers with hybrid FS algorithms (TMGWO, ISSA, BBPSO) on three datasets (Wisconsin Breast Cancer, Sonar, Differentiated Thyroid Cancer). The TMGWO hybrid approach achieved superior results in both feature selection and classification accuracy, significantly reducing model complexity and enhancing generalization.

Results
TMGWO Hybrid Approach: Superior Performance
The Two-phase Mutation Grey Wolf Optimization (TMGWO) hybrid approach consistently demonstrated superior results across experiments. When combined with various classifiers, TMGWO achieved higher accuracy, precision, and recall while significantly reducing the number of features. For instance, on the Breast Cancer dataset, TMGWO-SVM attained 96% accuracy using only 4 features, outperforming other methods and baseline configurations.
Outcome: TMGWO consistently outperformed other experimental methods in both feature selection and classification accuracy, making it the most effective strategy for optimizing high-dimensional data classification.
