Given scattered samples lying on a manifold M embedded in high-dimensional space, Hessian LLE , attempts the recovery of the underlying parameterization of the samples in an open, connected subset of low-dimensional space that is locally isometric to the original space. Webhigh-dimensional Euclidean space. The method, Hessian-based locally linear embedding, derives from a conceptual framework of local isometry in which the manifold M, viewed as a Riemannian submanifold of the ambient Euclidean space n, is locally isometric to an open, connected subset of Euclidean space d.

Hessian Eigenmapping¶ Hessian Eigenmapping (also known as Hessian-based LLE: HLLE) is another method of solving the regularization problem of LLE. It revolves around a hessian-based quadratic form at each neighborhood which is used to recover the locally linear structure.

Sammon's mapping is one of the first and most popular NLDR techniques. 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… WebJun 24, 2016 · We present the results of the application of locally linear embedding (LLE) to reduce the dimensionality of dereddened and continuum subtracted near-infrared spectra using a combination of models and real spectra of massive protostars selected from the Red MSX Source survey data base.

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 ...
