[−]
[src]
pub fn pr_auc<T, X, F, I>(data: I, convert_fn: F) -> Option<X> where
I: IntoIterator<Item = T>,
F: Fn(T) -> (bool, X),
X: Float,
Computes the area under a PR curve of a given classifier.
data
is a free-form IntoIterator
object and convert_fn
is a closure that converts each
data-point into a pair (ground_truth, prediction).
Returns None
if one of the classes is not present or any values are non-finite.
Otherwise, returns Some(area_under_curve)
.
