Fast, Warped Graph Embedding: Unifying Framework and One-Click Algorithm
Siheng Chen, Sufeng Niu, Leman Akoglu +2
What is the best way to describe a user in a social network with just a few numbers? Mathematically, this is equivalent to assigning a vector representation to each node in a graph…
Localization, Decomposition, and Dictionary Learning of Piecewise-Constant Signals on Graphs
Siheng Chen, Yaoqing Yang, José. M. F. Moura +1
Motivated by the need to extract meaning from large amounts of complex structured data, we consider three critical problems on graphs: localization, decomposition, and dictionary l…
Detecting Localized Categorical Attributes on Graphs
Siheng Chen, Yaoqing Yang, Shi Zong +2
Do users from Carnegie Mellon University form social communities on Facebook? Do signal processing researchers from tightly collaborate with each other? Do Chinese restaurants in M…
Signal Recovery on Graphs: Variation Minimization
Siheng Chen, Aliaksei Sandryhaila, José M. F. Moura +1
We consider the problem of signal recovery on graphs as graphs model data with complex structure as signals on a graph. Graph signal recovery implies recovery of one or multiple sm…
