Laplacian Eigenmaps

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.
