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 … 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 …

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.

WebGraph robustness-the ability of a graph to preserve its connectivity after the loss of nodes and edges-has been extensively studied to quantify how social, biological, … WebMay 20, 2024 · For example, fraudsters can create several transactions with deliberately chosen high credit users to escape GNN-based fraud detectors. This implies the necessity of investigating robust GNNs in safety-critical domains such as healthcare and financial system. There are already several surveys about the robustness on graph-structured data.
WebMay 5, 2024 · To demonstrate the effects of extending the graph on the robustness of the graph, we initially look at graphs with 88 nodes of which 3 are critical nodes, then we extend the graph three times: the first one has 184 nodes of which 6 are critical nodes, the second one has 376 nodes of which 12 are critical nodes and the last one has 760 nodes … WebGiven a clean graph, the supernet built upon our robust search space is trained in a single-path one-shot way. Then, the attack proxy produces several adversarial samples based on the clean graph and we search for robust GNNs with the proposed robustness metric. Finally, we evaluate the optimal robust GNN on graphs perturbed by the attacker.
