Mother class for all multi-class classification metrics.
Parameters¶
-
cm
Default →

Indicate if a high value is better than a low one or not.
-
requires_labels
Indicates if labels are required, rather than probabilities.
-
works_with_weights
Indicate whether the model takes into consideration the effect of sample weights
Methods¶

is_better_than
Indicate if the current metric is better than another one.
Parameters
- other
