A new locally linear embedding scheme in light of Hessian eigenmap

no code implementations16 Dec 2021 Liren Lin, Chih-Wei Chen

We provide a new interpretation of Hessian locally linear embedding (HLLE), revealing that it is essentially a variant way to implement the same idea of locally linear embedding (LLE).

The Unsupervised Method of Vessel Movement Trajectory Prediction
