Confident Learning uses class-dependent confidence thresholds to estimate likely label confusion and identify suspicious examples. Its theoretical guarantees depend on stated assumptions.\n\nCleanlab recommends out-of-sample probabilities, commonly generated by cross-validation, and can return issues ranked by label-quality scores. The probability columns must follow the same class order as the encoded labels. In-sample predictions can hide errors that a model has memorized.
