MUGEN: Generating Unlearnable Graph Examples for Multiple Learning Tasks

arXiv · AI, language, vision and robotics · article · Sep 1, 2026 · UTC

Graph data across diverse domains can expose valuable relational information to unauthorized representation learning, creating a pressing need for protection against such misuse. Unlearnable examples offer a data-level defense by perturbing a training release so that models trained on it fail to generalize to clean data. Existing methods generate unlearnable graph examples for only a specified downstream task. Consequently, a release protected against one task may remain learnable for other plausible uses, including node classification, graph classification, and link prediction, which the data
