Laplacian Eigenmaps - AAU-Dat/P5-Nonlinear-Dimensionality-Reduction GitHub Wiki
Introduction
Laplacian eigenmaps, are used to reduce the dimensions and extractung the feature to data points. In the aspect of operation efficiency, it avoids the adjacent map to re-build in the entire dataset after the new point arriving, so greatly reducing the computational complexity. Therefore it is often used for facial recognition.
