classifier performance

These four cases will now be used to introduce several commonly used terms for understanding and explaining classification performance. As mentioned earlier, a perfect classifier will have no entries for FP and FN (i.e., the number of FP = number of FN = 0). Sensitivityis the ability of a classifier to select all the cases that needto be selected

    Jul 05, 2020 · The techniques and metrics used to assess the performance of a classifier will be different from those used for a regressor, which is a type of model that attempts to predict a value from a continuous range. Both types of model are common, but for now, let’s limit our analysis to classifiers
