Classifying high-dimensional imbalanced data is a big challenge in mining
real-world big data. Existing algorithms are classifying the majority class
instances and get the maximum classification accuracy and minority class
instance is overpowered by getting misclassified. In real life applications
minority class instances are more significant than the majority class. For
classifying imbalanced data sets few techniques based on sampling (Under-sampling
/ over-sampling), cost sensitive learning methods and ensemble
learning are used. In our research, A new technique has been introduced,
\correlation-based feature grouping with decision tree for classifying high-dimensional
imbalanced data". We have assessed the dispatch of the the
proposed algorithm on few of the high dimensional imbalanced data sets
with different imbalance correspondences. The results are tremendously
better to work with high imbalanced data sets.
