Categorical Crossentropy

Description

Compute Categorical Crossentropy. The squared loss, in a sense, quantifies the error (or alternatively closeness) of the predicted label to the true label. When specialized to the case of probabilistic classifiers, this then can be interpreted as a reliability measure.

Usage

categorical_crossentropy(y_real, y_predicted)

Arguments

`y_real`	Observed values (integers) to compare with (in matrix format for multiclass classification).
`y_predicted`	Predicte values (probabiblities by class).
