WebMar 23, 2024 · The macroscopic behavior of networks, when facing random removal of nodes or edges, can be described as an inverse percolation process in a random graph. To determine whether a network remains operational when its elements (nodes or edges) fail at random, a “network robustness” criterion is used as a probabilistic measure. In this …

WebGiven a clean graph, the supernet built upon our robust search space is trained in a single-path one-shot way. Then, the attack proxy produces several adversarial samples based on the clean graph and we search for robust GNNs with the proposed robustness metric.
