Manifold.LocallyLinearEmbedding

Locally Linear Embedding (LLE) reconstructs each sample from its nearest neighbors and finds a low‑dimensional representation that preserves these local relationships.

constructor(
    nNeighbors: number = 5,
    nComponents: number = 2,
    reg: number = 0.001
)

Parameters

• nNeighbors (number, default 5): how many neighbors to use for the local reconstructions.
• nComponents (number, default 2): dimension of the returned embedding.
• reg (number, default 0.001): regularization value added to the covariance matrix to ensure numerical stability.

Methods

• fit(X: number[][]): void
• transform(X: number[][]): number[][]
• fitTransform(X: number[][]): number[][]

Example

const lle = new LocallyLinearEmbedding(5, 2);
const Y = lle.fitTransform(X);
