Recovering Graph-Structured Activations using Adaptive Compressive Measurements
Akshay Krishnamurthy, James Sharpnack, Aarti Singh
We study the localization of a cluster of activated vertices in a graph, from adaptively designed compressive measurements. We propose a hierarchical partitioning of the graph that…
