A training data set is a data set of examples used during the learning process and is used to fit the parameters (e.g., weights) of, for example, a classifier.

Instead, measures such as the phi coefficient, Matthews correlation coefficient, informedness or Cohen's kappa may be preferable to assess the performance of a binary classifier.

The candidate instances are those for which the prediction is most ambiguous.

The system then selects the instances for which it is the least confident and queries the teacher for the labels.
