Struct OrthogonalRandomFeatures 

pub struct OrthogonalRandomFeatures { /* private fields */ }

Orthogonal Random Features for improved variance.

Uses orthogonalized random matrices for better approximation quality, especially for smaller n_components.

Reference: Yu et al. (2016). “Orthogonal Random Features.”

Implementations

impl OrthogonalRandomFeatures

pub fn new(input_dim: usize, config: RffConfig) -> Result<Self>

Create orthogonal random features.

Note: For simplicity, this currently uses standard RFF. Full orthogonalization would require QR decomposition.

pub fn transform(&self, x: &[f64]) -> Result<Vec<f64>>

Transform a single input vector.

pub fn transform_batch(&self, data: &[Vec<f64>]) -> Result<Vec<Vec<f64>>>

Transform multiple input vectors.

pub fn output_dim(&self) -> usize

Get the output dimension.

Trait Implementations

impl Clone for OrthogonalRandomFeatures

fn clone(&self) -> OrthogonalRandomFeatures

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrthogonalRandomFeatures

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

Formats the value using the given formatter.
