A Study imbalance handling by various data sampling methods in binary classification
This is an incremental study applying standard techniques to a specific dataset for educational purposes.
The researchers tackled class imbalance in binary classification by comparing over-sampling and under-sampling methods on a Kaggle dataset, aiming to improve overall performance through balanced class representation.
The purpose of this research report is to present the our learning curve and the exposure to the Machine Learning life cycle, with the use of a Kaggle binary classification data set and taking to explore various techniques from pre-processing to the final optimization and model evaluation, also we highlight on the data imbalance issue and we discuss the different methods of handling that imbalance on the data level by over-sampling and under sampling not only to reach a balanced class representation but to improve the overall performance. This work also opens some gaps for future work.
