Hyperparameters in Score-Based Membership Inference Attacks
A new shadow-model hyperparameter selection method (KL-LiRA) makes membership inference attacks nearly as effective without knowing target hyperparameters, and training-data-based hyperparameter tuning shows no detectable extra MIA leak under DP.
