Oversampling and undersampling in data analysis are techniques used to adjust the class distribution of a data set (i.e. the ratio between the different classes/categories represented). * Oversampling and undersampling are opposite and roughly equivalent techniques. They both involve using a bias to select more samples from one class than from another. * The usual reason for oversampling is to correct for a bias in the original dataset. One scenario * where it is useful is when training a classifier using labelled training data from a biased source, since * labelled training data is valuable but often comes from un-representative sources. * For example, suppose we have a sample of 1000 people of which 66.7% are male. We know the general population is 50% female, and we may wish to adjust our dataset to represent this. Simple oversampling will select each female example twice, and this copying will produce a balanced dataset of 1333 samples with 50% female. Simple undersampling will drop some of the male samples at random to give a balanced dataset of 667 samples, again with 50% female.There are also more complex oversampling techniques, including the creation of artificial data points . |
