Random sampling of bandlimited signals on graphs
Gilles Puy, Nicolas Tremblay, Rémi Gribonval +1
We study the problem of sampling k-bandlimited signals on graphs. We propose two sampling strategies that consist in selecting a small subset of nodes at random. The first strategy…
Accelerated Spectral Clustering Using Graph Filtering Of Random Signals
Nicolas Tremblay, Gilles Puy, Pierre Borgnat +2
We build upon recent advances in graph signal processing to propose a faster spectral clustering algorithm. Indeed, classical spectral clustering is based on the computation of the…
Subgraph-based filterbanks for graph signals
Nicolas Tremblay, Pierre Borgnat
We design a critically-sampled compact-support biorthogonal transform for graph signals, via graph filterbanks. Instead of partitioning the nodes in two sets so as to remove one ev…
