The study of the null space embedding of the graph Laplacian $\mathbf{\mathcal L}_0$ has spurred new research and applications, such as spectral clustering algorithms with theoretical guarantees and estimators of the Stochastic Block Model.

Many manifold embedding algorithms fail apparently when the data manifold has a large aspect ratio (such as a long, thin strip).

Manifold embedding algorithms map high-dimensional data down to coordinates in a much lower-dimensional space.
