Struct LLE 

pub struct LLE { /* private fields */ }

Locally Linear Embedding (LLE) dimensionality reduction

LLE finds a low-dimensional embedding that preserves local linear structure. Each point is reconstructed from its neighbors with fixed weights, and the embedding preserves these reconstruction weights.

Implementations

impl LLE

pub fn new(n_neighbors: usize, ncomponents: usize) -> Self

Creates a new LLE instance

Arguments

• n_neighbors - Number of neighbors to use
• n_components - Number of dimensions in the embedding

pub fn with_regularization(self, reg: f64) -> Self

Set the regularization parameter

pub fn with_method(self, method: &str) -> Self

Set the LLE method variant

pub fn fit<S>(&mut self, x: &ArrayBase<S, Ix2>) -> Result<()>

where S: Data, S::Elem: Float + NumCast,

Fits the LLE model to the input data

Arguments

• x - The input data, shape (n_samples, n_features)

Returns

• Result<()> - Ok if successful, Err otherwise

pub fn transform<S>(&self, x: &ArrayBase<S, Ix2>) -> Result<Array2<f64>>

where S: Data, S::Elem: Float + NumCast,

Transforms the input data using the fitted LLE model

Arguments

• x - The input data, shape (n_samples, n_features)

Returns

• Result<Array2<f64>> - The transformed data, shape (n_samples, n_components)

pub fn fit_transform<S>(&mut self, x: &ArrayBase<S, Ix2>) -> Result<Array2<f64>>

where S: Data, S::Elem: Float + NumCast,

Fits the LLE model and transforms the data

Arguments

• x - The input data, shape (n_samples, n_features)

Returns

• Result<Array2<f64>> - The transformed data, shape (n_samples, n_components)

pub fn embedding(&self) -> Option<&Array2<f64>>

Returns the embedding

pub fn reconstruction_weights(&self) -> Option<&Array2<f64>>

Returns the reconstruction weights
