Enum EmbeddingType 

pub enum EmbeddingType {
    GaussianRandom,
    SparseRandom,
    FastJohnsonLindenstrauss,
}

Random projection embedding methods.

Variants

GaussianRandom

Gaussian random projection: entries i.i.d. N(0, 1/k).

SparseRandom

Sparse random projection (Achlioptas 2003): entries ±√(3/k) with probability 1/6 each, 0 with probability 2/3.

FastJohnsonLindenstrauss

Fast Johnson-Lindenstrauss transform (SRHT approximation). Currently implemented as a Gaussian projection; a structured Hadamard construction can replace this without breaking the API.

Trait Implementations

impl Clone for EmbeddingType

fn clone(&self) -> EmbeddingType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EmbeddingType

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

Formats the value using the given formatter.

impl PartialEq for EmbeddingType

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