SMOTEfamily: SMOTE family package for Data Generation

Description

The collection of SMOTE algorithm and some of its variants for oversampling numeric data

Arguments

Details

This package is built to collect several oversampling techniques for Imbalanced data which are parts of my doctorate research. Data to be used with these techniques in this package must be all numeric with one nominal attribute worked as the target class.

Examples

Run this code

	if (FALSE) {
    	data_example = sample_generator(10000,ratio = 0.80)
	genData = SMOTE(data_example[,-3],data_example[,3])
	genData_2 = SMOTE(data_example[,-3],data_example[,3],K=7)
