Enum MaxFeatures 

pub enum MaxFeatures {
    Auto,
    All,
    Sqrt,
    Third,
    Count(usize),
}

Variants

Auto

Task-aware default: sqrt for classification, third for regression.

All

Use all features at each split.

Sqrt

Use floor(sqrt(feature_count)) features.

Third

Use roughly one third of the features.

Count(usize)

Use exactly this many features, capped to the available count.

Implementations

impl MaxFeatures

pub fn resolve(self, task: Task, feature_count: usize) -> usize

Trait Implementations

impl Clone for MaxFeatures

fn clone(&self) -> MaxFeatures

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MaxFeatures

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MaxFeatures

fn eq(&self, other: &MaxFeatures) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
