Graph robustness
WebGraph robustness or network robustness is the ability that a graph or a network preserves its connectivity or other properties after the loss of vertices and edges, which has been a central problem in the research of complex networks. In this paper, we introduce the Modified Zagreb index and Modified Zagreb index centrality as novel measures to study … WebHis works on subspace clustering on graphs as well as adversarial robustness of graph neural networks have received the best research paper awards at ECML-PKDD and KDD. Stephan acquired his doctoral degree at RWTH Aachen University, Germany in the field of computer science. From 2012 to 2015 he was an associate of Carnegie Mellon …

WebD, where 2 ≤ D ≤ N/NL, we propose graph constructions generating strong structurally controllable networks. We also compute the number of edges in graphs, which are maximal for improved robustness measured by the algebraic connectivity and Kirchhoff index. For the controllability analysis, we utilize the notion of zero forcing sets in graphs. WebMay 27, 2024 · The purpose of the present survey is to catalogue the robustness characteristics that have been proposed for complex networks. We focus on those that …
WebSep 23, 2024 · If you assume that the observed graph at training time is clean, and that at test time the graph has not changed, then you are right, we trivially have provable robustness since it directly follows from the assumptions. Another scenario is that the observed graph at training time is clean, but at test time the graph could have been … http://ece-research.unm.edu/chaouki/PAPERS/Tech-Reports/SAND-Report-Byrne-Feddema-Abdallah.pdf
