The interface of a measure which compute a value of O from expected and actual values of I.
A measure that is decomposable by instances and aggregated by averaging.
A measure that is aggregated from e.g. instance-wise computations of the respective measure and which is then aggregated, e.g. taking the mean.
Class for getting metrics by their name for single- and multilabel classifiers.
This transformer transforms a decomposable double measure from a scoring function to a loss or vice versa.
