Optimizer choice impacts neural network training data privacy, study finds

A new research paper explores how different optimization algorithms used in training neural networks can impact the privacy of the training data. The study, which extends previous work on Karush-Kuhn-Tucker conditions, suggests that optimizers like SGD and Muon leave distinct "fingerprints" that can be exploited to reconstruct training examples. In contrast, Adam, particularly in its $\ell_\infty$ implicit-bias regime, appears to be more resistant to such data reconstruction attacks. AI

IMPACT The choice of optimizer in neural network training may have significant implications for the privacy of the training data, potentially influencing future model development and deployment strategies.
