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…
Energy Efficient Distributed Coding for Data Collection in a Noisy Sparse Network
Yaoqing Yang, Soummya Kar, Pulkit Grover
We consider the problem of data collection in a two-layer network consisting of (1) links between distributed agents and a remote sink node; (2) a sparse network formed by thes…
Rate Distortion for Lossy In-network Function Computation: Information Dissipation and Sequential Reverse Water-Filling
Yaoqing Yang, Pulkit Grover, Soummya Kar
We consider the problem of distributed lossy linear function computation in a tree network. We examine two cases: (i) data aggregation (only one sink node computes) and (ii) consen…
