Enum Skipping 

pub enum Skipping {
    Auto,
    On,
    Off,
}

Whether the search skips thresholds: the interval pruner, and the skipping and early stops of the depth-2 solver’s scan.

Skipping assumes what misclassification guarantees: moving n instances into a leaf never lowers its cost and raises it by at most n, and removing them never raises it and lowers it by at most n. A custom loss may not, so Auto turns skipping off for one. On forces it, and the depth-2 solver then counts the moves that break the assumption.

With a minimum support above 1 the interval pruner stays off whatever the setting, since its rules do not hold there for any loss; On then forces only the depth-2 solver’s skipping, whose argument does not involve the support.

Variants

Auto

On for misclassification, off for a custom loss.

On

On whatever the loss.

Off

Off.

Implementations

impl Skipping

pub fn applies(self, loss: &Loss) -> bool

Whether thresholds are skipped for this loss.

The interval pruner adds its own condition, a minimum support of 1; see IntervalsPruner::is_sound.
