Researchers have developed new post-processing methods to create differentially private machine learning models without retraining. These techniques, random selection and linear combination, allow for the generation of models that meet any specified differential privacy requirement, given a set of pre-existing models with varying privacy-utility trade-offs. The study provides detailed privacy accounting using R'enyi DP and privacy loss distributions, demonstrating the effectiveness of these approaches empirically on various datasets and models. AI
IMPACT Enables flexible adaptation of deployed models to evolving privacy regulations without costly retraining.
