Abstract: Finite time-vertex graph signals (FTVGS) provide an efficient representation for capturing spatio-temporal correlations across multiple data sources on irregular structures. Although ...

Abstract: Quantization-based graph transform (QGT) provides a unique perspective on spectrum sensing in cognitive radio networks. Conventional QGT-based spectrum sensing algorithms leverage the ...

Graph: generic data representation form describing the geometric structures of data domains. We denote an undirected, connected, weighted graph as $\mathcal{G ...

title: Vertex Coloring Let $G = (V,E)$ be a graph. A **vertex coloring** (or just **coloring** usually if it's clear from context that we're coloring vertices) is a ...
