WebSep 1, 2024 · A more realistic scenario, graph injection attack (GIA), is studied in [14, 13], which injects new vicious nodes instead of modifying the original graph. A greedy … WebMethodologically, we provide an approximation strategy to linearize the model we attack and then derive an approximate closed-from solution with a lower time cost. To have a fair comparison with existing attack methods that manipulate the original graph, we adapt them to the new attack scenario by injecting vicious nodes.
