Supervised locally linear embedding

WebAbstract. Locally linear embedding (LLE) is a recently proposed method for unsupervised nonlinear dimensionality reduction. It has a number of attractive features: it does not require an iterative algorithm, and just a few parameters need to be set. Two extensions of LLE to su-pervised feature extraction were independently proposed by the authors WebMar 7, 2024 · The locally linear embedding aims to extract the significant features by only digging the individual geometric structure of original data set, for which the intrinsic features can not be completely expressed. In this study, two LLE-based multi-structure fusion methods are proposed.
