Struct NystroemFeatures 

pub struct NystroemFeatures { /* private fields */ }

Nystroem approximation as random features.

Represents kernel approximation using Nystroem method, which uses a subset of training points as landmarks.

Implementations

impl NystroemFeatures

pub fn new(landmarks: Vec<Vec<f64>>, kernel_type: KernelType) -> Result<Self>

Create Nystroem features from landmark points.

Arguments

• landmarks - Subset of training points to use as landmarks
• kernel_type - The kernel to approximate

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

Transform a single input vector to Nystroem features.

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

Transform multiple input vectors.

pub fn n_landmarks(&self) -> usize

Get the number of landmarks (output dimension).
