Abstract: In this article, we propose and develop a spectral graph based vertex varying Wiener filtering framework in the joint vertex-frequency domain for denoising of graph signals defined on ...

Abstract: Graph pattern mining discovers important patterns in graphs. It is both computation-and memory-intensive, characterized by numerous set operations and irregular memory access. Graph pattern ...

Given an undirected complete graph G = (V,E) G = (V, E) on kn k n vertices with a non-negative weight function on E E, the maximum-weight k k -cycle (k k -path) packing problem aims to compute a set ...
