Enum EpmReductionMethod 

pub enum EpmReductionMethod {
    PCA,
    RandomProjection(u64),
    TruncateDims,
    MeanPooling,
}

Algorithm used by EpmPipelineStage::DimensionReduce.

The Epm prefix disambiguates from dimension_reducer::ReductionMethod.

Variants

PCA

Simplified PCA via per-dimension mean centering and variance scaling.

RandomProjection(u64)

Deterministic random Gaussian projection seeded with seed.

TruncateDims

Keep only the first target_dim components.

MeanPooling

Pool all components into target_dim by local mean-pooling.

Trait Implementations

impl Clone for EpmReductionMethod

fn clone(&self) -> EpmReductionMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpmReductionMethod

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

Formats the value using the given formatter.

impl PartialEq for EpmReductionMethod

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