WebbThe calibration module allows you to better calibrate the probabilities of a given model, or to add support for probability prediction. Well calibrated classifiers are probabilistic classifiers for which the output of the predict_proba method can be directly interpreted as a confidence level. WebbThe plan now is to replace the probability of the union of events by a sum of probabilities of individual events by means of the union bound. However, to make sure that the resulting bound is not too loose, we operate as follows. We first condition on C1 and Yn.
