Rashomon sets in ML offer robustness but increase privacy risks

A new paper explores the complex implications of "Rashomon sets" in machine learning, which are collections of multiple near-optimal models rather than a single one. While these diverse sets can enhance robustness by allowing practitioners to switch models if one is compromised, they also increase the risk of information leakage from the training data. The research theoretically and empirically analyzes this trade-off between robustness and privacy, highlighting that Rashomon sets remain stable under minor distribution shifts, thus not requiring immediate re-computation. The findings underscore the dual nature of Rashomon sets, presenting both opportunities and challenges for developing trustworthy machine learning systems. AI
