arXiv:2605.24420v1 Announce Type: new Abstract: Batch Normalization (BN) is widely adopted to enable faster convergence and more stable training of deep neural networks. However, its impact on privacy and memorization has remained largely unexplored. In this work, we investigate the effect of BN layers on the memorization of atypical or outlier samples and its implications for privacy leakage. We conduct an extensive empirical study using three complementary approaches: (i) unintended memorization of out-of-distribution training samples, (ii) per-sample influence measured via gradient norms, a
Ongoing research into the security and ethical implications of AI models is uncovering fundamental properties of widely used techniques like Batch Normalization.
This finding highlights a critical trade-off between model performance/stability and data privacy, which can have significant legal, ethical, and reputational consequences for AI developers and deployers.
AI model design and training practices will need to incorporate more robust privacy-preserving mechanisms or alternative normalization techniques, especially in sensitive applications.
