Machine learning models face imbalanced data as a significant challenge after reaching over two decades of development. The prevalent class imbalance creates imbalanced models which prefer the majority group while reducing performance numbers across minority classes. This research presents an optimized version of SMOTE for Imbalanced Data handling through machine learning (SMOTE-IDEA) that acts as a technique for imbalanced data classification. The process of making minority-class synthetic samples to address class imbalance has been traditionally handled through SMOTE approaches. Standard SMOTE applications allow unwanted irrelevant data points to enter the data which produces undesirable results. The research suggests a new version of SMOTE which addresses past limitations to enhance the oversampling procedure. SMOTE technique generates synthetic data more efficiently through several additions. The method selects significant features through an automated process that removes unimportant information. Sample filtering and high-quality synthetic instance generation take place as part of this method. The method adapts weight distribution schemes to ensure that data generation occurs primarily in high-density regions thereby improving minority class composition. Several classification methods analyzed different ratio-imbalanced datasets to evaluate the newly upgraded SMOTE approach. The proposed strategy demonstrates superior performance against traditional SMOTE implementation and top-level benchmark approaches by delivering improved classifications in terms of accuracy and precision in addition to recall and F1-score operation on minority and majority groups.
