Graph adversarial methods
WebThe adversarial training principle is applied to enforce our latent codes to match a prior Gaussian or uniform distribution. Based on this framework, we derive two variants of the adversarial models, the adversarially regularized graph autoencoder (ARGA) and its variational version, and adversarially regularized variational graph autoencoder ... Webadopt optimization methods from other elds (especially im-age adversarial attack), ignoring the unique structure of graph data. In this work, we propose to attack in a graph-specic manner utilizing the inherent structure of a graph. 3 A Unied Framework for Query-Based Adversarial Attacks on Graphs We now present a unied framework for query ...
