Mixing Classifiers to Alleviate the Accuracy-Robustness Trade-Off

no code implementations26 Nov 2023 Yatong Bai, Brendon G. Anderson, Somayeh Sojoudi

However, standard learning models often suffer from an accuracy-robustness trade-off, which is a limitation that must be overcome in the control of safety-critical systems that require both high performance and rigorous robustness guarantees.

Improving the Accuracy-Robustness Trade-Off of Classifiers via Adaptive Smoothing

1 code implementation29 Jan 2023 Yatong Bai, Brendon G. Anderson, Aerin Kim, Somayeh Sojoudi

While prior research has proposed a plethora of methods that build neural classifiers robust against adversarial robustness, practitioners are still reluctant to adopt them due to their unacceptably severe clean accuracy penalties.
