Graph robustness
WebAbstract. A cursory reading of the literature suggests that we have made a lot of progress in designing effective adversarial defenses for Graph Neural Networks (GNNs). Yet, the standard methodology has a serious flaw – virtually all of the defenses are evaluated against non-adaptive attacks leading to overly optimistic robustness estimates ... 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 …

We focus on those that … WebOct 8, 2024 · Robustness, Resillience, Reliability; in the most general case within Operations Research. Let us suppose you want to find the classical shortest path in a graph between two different nodes. However, you know in advance that at most one edge could be unavailable or present a failure. e.g. for rehabilitation works.
WebMy research interest is in bridging "system 1" and "system 2" reasoning. One approach I find promising lies in allowing neural networks to reason over the underlying graph structure … WebThe study of network robustness is a critical tool in the characterization and sense making of complex interconnected systems such as infrastructure, communication and social …
WebRobustness, the ability to withstand failures and perturbations, is a critical attribute of many complex systems including complex networks . The study of robustness in … 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 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.
