Manifold Graph Signal Restoration using Gradient Graph Laplacian Regularizer
Fei Chen, Gene Cheung, Xue Zhang
In the graph signal processing (GSP) literature, graph Laplacian regularizer (GLR) was used for signal restoration to promote piecewise smooth / constant reconstruction with respec…

Fast Computation of Generalized Eigenvectors for Manifold Graph Embedding
Fei Chen, Gene Cheung, Xue Zhang
Our goal is to efficiently compute low-dimensional latent coordinates for nodes in an input graph -- known as graph embedding -- for subsequent data processing such as clustering.…
