Graph backdoor
WebFeb 21, 2024 · This work proposes a novel graph backdoor attack that uses node features as triggers and does not need knowledge of the GNNs parameters, and finds that feature triggers can destroy the feature spaces of the original datasets, resulting in GNN's inability to identify poisoned data and clean data well. Graph neural networks (GNNs) have shown … WebWe can close back door paths by controlling the variables on those back door paths. We can do that by statistically holding these variables constant.

WebJun 28, 2024 · A backdoored model will misclassify the trigger-embedded inputs into an attacker-chosen target label while performing normally on other benign inputs. There are already numerous works on backdoor attacks on neural networks, but only a few works consider graph neural networks (GNNs). im warping here chordsWebgraphs, backdoor attacks inject triggers in the form of sub-graphs [18]. An adversary can launch backdoor attacks by manipulating the training data and corresponding labels. Fig. 2 illustrates the flow of a subgraph-based backdoor attack against GNNs.
