Closing the Gap: Achieving Better Accuracy-Robustness Tradeoffs against Query-Based Attacks

no code implementations15 Dec 2023 Pascal Zimmer, Sébastien Andreina, Giorgia Azzurra Marson, Ghassan Karame

Although promising, existing defenses against query-based attacks share a common limitation: they offer increased robustness against attacks at the price of a considerable accuracy drop on clean samples.
