Researchers have developed MUGEN, a novel framework designed to create "unlearnable" graph examples that protect data across multiple machine learning tasks simultaneously. Unlike previous methods that focused on single tasks, MUGEN generates a single perturbed dataset that safeguards against unauthorized representation learning for various applications like node classification, graph classification, and link prediction. The framework utilizes a Task-Aligned Separability Objective (TASO) and Type-Adaptive Perturbation (TAP) to ensure that models trained on the perturbed data fail to generalize to clean data, demonstrating effectiveness across different GNN backbones and learning paradigms.
