Graph robustness
WebApr 15, 2024 · The main contributions of this work can be summarized as follows: An end-to-end transformer-based graph attention tracking framework is proposed. To the best of our knowledge, this is the first work to introduce the graph attention into transformer for extracting the robust feature embedding information of the target.

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. Finally, we evaluate the optimal robust GNN on graphs perturbed by the attacker.
