Smoothing Graph Signals via Random Spanning Forests

Yusuf Yigit Pilavci, Pierre-Olivier Amblard, Simon Barthelmé, Nicolas Tremblay

ICASSP 2020accepted

Another facet of the elegant link between random processes on graphs and Laplacian-based numerical linear algebra is uncovered: based on random spanning forests, novel Monte-Carlo estimators for graph signal smoothing are proposed. These random forests are sampled efficiently via a variant of Wilson…

Spectral Graph Wavelet Transform as Feature Extractor for Machine Learning in Neuroimaging

Yusuf Yigit Pilavci, Nicolas Farrugia

ICASSP 2019accepted

Graph Signal Processing has become a very useful framework for signal operations and representations defined on irregular domains. Exploiting transformations that are defined on graph models can be highly beneficial when the graph encodes relationships between signals. In this work, we present the b…
