WebJan 1, 2015 · Donoho and Grimes proposed the Hessian LLE (HLLE), an approach similar to the Laplacian eigenmaps. It computes the Hessian instead of the Laplacian of the graph. The authors alleged that the Hessian is better suited than the Laplacian for detecting linear patches on the manifold. The major contribution of this approach is that it proposes a ...

The self-organizing map (SOM, also called Kohonen map) and its probabilistic variant generative topographic mapping (GTM) use a point representation in the embedded space to form a latent variable model based on a non-linear mapping from the embedded space to the high-dimensional space. These techniques a…

WebLLE is a topology preserving manifold learning method. All manifold learning algorithms assume that dataset lies on a smooth non linear manifold of low dimension and a mapping f: RD -> Rd (D>>d) can be found by preserving one or more properties of the higher dimension space. Topology preservation means the neighborhood structure is intact.
