Filter Learning for Subgraphs: Algebras and Performance Risk Bounds

Purui Zhang, Feng Ji, Yanan Zhao, Bihan Wen, Wee Peng Tay

Graph signal processing tasks that leverage spectral information typically assume access to the complete graph topology, which is often unavailable in practice. We propose a systematic framework for subgraph filter learning (SFL), where subgraph-supported operators approximate am…Read more
