Rows and columns represent true and modified labels. Numbers represent the number of samples with correct and modified labels. (a) little; (b) medium; and (c) heavy mislabeling. Correlation coefficients represent the amount of mislabeling (larger correlation coefficients correspond to less mislabeling).
