Enum ThresholdStrategy 

pub enum ThresholdStrategy {
    Mean,
    Median,
    Value(f64),
    Percentile(f64),
}

Strategy for computing the importance threshold in SelectFromModelExt.

Variants

Mean

Threshold equals the arithmetic mean of all feature importances.

Median

Threshold equals the median of all feature importances.

Value(f64)

User-supplied explicit threshold value.

Percentile(f64)

Keep features in the top p% of importance scores (0 < p <= 100).

For example, Percentile(25.0) retains features whose importance is at or above the 75th-percentile value (i.e., the top 25%).

Trait Implementations

impl Clone for ThresholdStrategy

fn clone(&self) -> ThresholdStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ThresholdStrategy

impl Debug for ThresholdStrategy

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

Formats the value using the given formatter.

impl Default for ThresholdStrategy

fn default() -> ThresholdStrategy

Returns the “default value” for a type.

impl PartialEq for ThresholdStrategy

fn eq(&self, other: &ThresholdStrategy) -> 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.
