A Novel Similarity Based Under-sampling of Imbalanced Datasets by Maira Anis

Implementing SMOTE instead.

sachag678 commented 7 years ago

Implementing undersampling of majority class since, SMOTE requires adding new synthetic data into a sequence which messes up the sequence. Need to find a way to make new synthetic sequence data.

sachag678 commented 7 years ago

Undersampling on the majority class performs better than the initial sampling algorithm that was implemented.

sachag678 commented 7 years ago

Implemented Random undersampling which performs better than just removing cases in succession.
