- Signal Recovery on Graphs: Fundamental Limits of Sampling Strategies . . .
Abstract: This paper builds theoretical foundations for the recovery of a newly proposed class of smooth graph signals, approximately bandlimited graph signals, under three sampling strategies: uniform sampling, experimentally designed sampling, and active sampling We then state minimax lower bounds on the maximum risk for the approximately

- Sampling and Recovery of Graph Signals - ScienceDirect
First, we illustrate the conditions for perfect recovery of bandlimited graph signals from samples collected over a selected set of vertices Then, we describe some sampling design criteria proposed in the literature to mitigate the effect of noise and model mismatching when performing graph signal recovery

- Signal recovery on graphs: Random versus experimentally designed sampling
We propose a new class of smooth graph signals, called approximately bandlimited We then propose two recovery strategies based on random sampling and experimentally designed sampling
