Efficient Sampling Set Selection for Bandlimited Graph Signals Using Graph Spectral Proxies
Aamir Anis, Akshay Gadde, Antonio Ortega
We study the problem of selecting the best sampling set for bandlimited reconstruction of signals on graphs. A frequency domain representation for graph signals can be defined usin…

Guided Signal Reconstruction with Application to Image Magnification
Akshay Gadde, Andrew Knyazev, Dong Tian +1
We study the problem of reconstructing a signal from its projection on a subspace. The proposed signal reconstruction algorithms utilize a guiding subspace that represents desired…

A Probabilistic Interpretation of Sampling Theory of Graph Signals
Akshay Gadde, Antonio Ortega
We give a probabilistic interpretation of sampling theory of graph signals. To do this, we first define a generative model for the data using a pairwise Gaussian random field (GRF)…
