mlr_measures_classif.tp {mlr3} | R Documentation |
True Positives
Description
Measure to compare true observed labels with predicted labels in binary classification tasks.
Details
This measure counts the true positives, i.e. the number of predictions correctly indicating a positive class label.
Dictionary
This Measure can be instantiated via the dictionary mlr_measures or with the associated sugar function msr()
:
mlr_measures$get("classif.tp") msr("classif.tp")
Parameters
Empty ParamSet
Meta Information
Type:
"binary"
Range:
[0, \infty)
Minimize:
FALSE
Required prediction:
response
Note
The score function calls mlr3measures::tp()
from package mlr3measures.
If the measure is undefined for the input, NaN
is returned.
This can be customized by setting the field na_value
.
