Second, to model label relation dependencies and develop inter-dependent classifiers, we employ multi-hop graph neural networks (consisting of Probabilistic GNN and Iterative GNN), where the layer aggregation …
WebMar 3, 2024 · Generative adversarial network (GAN) is widely used for generalized and robust learning on graph data. However, for non-Euclidean graph data, the existing GAN-based graph representation methods generate negative samples by random walk or traverse in discrete space, leading to the information loss of topological properties (e.g. … Webdetection. The knowledge graph consists of two types of entities - Person and BankAccount. The missing target triple to predict is (Sam;allied_with;Joe). Original KGE model predicts this triple as True. But a malicious attacker uses the instance attribution methods to either (a) delete an adversarial triple or (b) add an adversarial triple.
