Abstract
Disclosed method for generating synthetic data for minority classes in a very large dataset comprises grouping samples stored on several devices, into different groups. A pivot is identified to be used as a reference for grouping the samples into bins. The samples are assigned to a bin, based on a closest pivot. The samples are regrouped into different groups, based on identities of the bins, and each of the groups is distributed to the several devices. Samples belonging to majority class and minority classes for which synthetic data is not being generated are removed from each of the different groups. Samples of each of these groups are arranged in different M-Trees to facilitate identification of K-nearest neighbours for each sample within each of the different groups to generate K pairs of nearest neighbours. Finally, synthetic samples are generated for the K pairs of nearest neighbours by creating random samples.
