Feature selection strategy for FeatureUnion

Variants

None

No feature selection (keep all features)

VarianceThreshold(Float)

Select top k features based on variance

TopK(usize)

Select top k features by count

ImportanceThreshold(Float)

Select features with importance above threshold

TopPercentile(Float)

Select top percentage of features

Trait Implementations

impl Clone for FeatureSelectionStrategy

fn clone(&self) -> FeatureSelectionStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureSelectionStrategy

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

Formats the value using the given formatter.

impl Default for FeatureSelectionStrategy

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for FeatureSelectionStrategy

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

impl Copy for FeatureSelectionStrategy

impl StructuralPartialEq for FeatureSelectionStrategy
