Mundle R.V and Chaudhari M.S

As technology is increasing,the data storage regarding each technology also increases.Many problems occur when large data is supposed to be handled.One such problem in data mining and machine learning techniques is class imbalance.The overall emphasis on how the class imbalance problem is solved using various techniques. Several techniques such as data processing, algorithmic approach and others are used for solving the skewed data problem of class imbalance. Data processing can be further classified into oversampling and undersampling which deals with the majority and minority class samples.These techniques are very useful for solving the class imbalance problem.
