False Omission Rate
Description
Measure to compare true observed labels with predicted labels in binary classification tasks.
Details
The False Omission Rate is defined as
\frac{\mathrm{FN}}{\mathrm{FN} + \mathrm{TN}}.
This measure is undefined if FN + TN = 0.
Dictionary
This Measure can be instantiated via the dictionary mlr_measures or with the associated sugar function msr():
mlr_measures$get("classif.fomr")
msr("classif.fomr")
Parameters

Note
The score function calls mlr3measures::fomr() from package mlr3measures.
If the measure is undefined for the input, NaN is returned.
This can be customized by setting the field na_value.
