Comparison of classification domains for the LR method with and without oversampling. Top panel: LR classification domains showing class probabilities for training with oversampling. The oversampling is illustrated by repeating the pulsar markers with a shift: the number of markers is equal to the number of times the pulsar appears in training. Bottom panel: repeat of Fig. 11 for the convenience of comparison with the oversampled training in the top panel. In both panels the domains are obtained by averaging over 100 random splits into training and testing samples.
