On the Stability of Low Pass Graph Filter With a Large Number of Edge Rewires
Hoang-Son Nguyen, Yiran He, Hoi-To Wai
Recently, the stability of graph filters has been studied as one of the key theoretical properties driving the highly successful graph convolutional neural networks (GCNs). The sta…

Detecting Central Nodes from Low-rank Excited Graph Signals via Structured Factor Analysis
Yiran He, Hoi-To Wai
This paper treats a blind detection problem to identify the central nodes in a graph from filtered graph signals. Unlike prior works which impose strong restrictions on the data mo…

Identifying First-order Lowpass Graph Signals using Perron Frobenius Theorem
Yiran He, Hoi-To Wai
This paper is concerned with the blind identification of graph filters from graph signals. Our aim is to determine if the graph filter generating the graph signals is first-order l…
