Adversarial attacks on graph-level embedding methods: a case study

As the number of graph-level embedding techniques increases at an unprecedented speed, questions ariseabout their behavior and performance when training data undergo perturbations. This is the case when anexternal entity maliciously alters training data to invalidate the embedding. This paper explores theeffects of such attacks on some graph datasets by applying different graph-level embedding techniques.The main attack strategy involves manipulating training data to produce an altered model. In thiscontext, our goal is to go in-depth about methods, resources, experimental settings, and performanceresults to observe and study all the aspects that derive from the attack stage.
