The decomposition of the higher-order homology embedding constructed from the $k$-Laplacian

1 code implementation NeurIPS 2021 Yu-Chia Chen, Marina Meilă

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.

Helmholtzian Eigenmap: Topological feature discovery & edge flow learning from point cloud data

no code implementations13 Mar 2021 Yu-Chia Chen, Weicheng Wu, Marina Meilă, Ioannis G. Kevrekidis

In this work, we propose the estimation of the manifold Helmholtzian from point cloud data by a weighted 1-Laplacian $\mathcal L_1$.

Selecting the independent coordinates of manifolds with large aspect ratios

2 code implementations NeurIPS 2019 Yu-Chia Chen, Marina Meilă

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

Manifold Coordinates with Physical Meaning

2 code implementations29 Nov 2018 Samson Koelle, Hanyu Zhang, Marina Meila, Yu-Chia Chen

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