MI Reduction
Mutual Information (MI) reduction is identified as a primary factor behind the effectiveness of Unlearnable Examples (UEs). By reducing the MI between clean and poisoned features, models struggle to generalize from the poisoned data.
Covariance Reduction
The paper proposes achieving MI reduction by minimizing the conditional covariance of intra-class poisoned features. This approach maximizes cosine similarity among intra-class features, impeding generalization.
MI-UE Method
The novel Mutual Information Unlearnable Examples (MI-UE) method optimizes a mutual information reduction loss, maximizing intra-class cosine similarity and minimizing inter-class cosine similarity to prevent class collapse.

Case Study: Protecting Medical Imaging Data
In a scenario involving sensitive medical imaging datasets, MI-UE was deployed to prevent unauthorized deep models from illicitly learning patient data. The system successfully impaired generalization of external models, reducing their test accuracy to random guessing levels while preserving data utility for authorized users. This demonstrated the practical applicability of MI-UE in high-stakes privacy environments.
Key Statistic: Achieved near-random guessing level accuracy for unauthorized models.
