Label sanitization against label flip** poisoning attacks

A Paudice, L Muñoz-González, EC Lupu - ECML PKDD 2018 Workshops …, 2019 - Springer
Many machine learning systems rely on data collected in the wild from untrusted sources,
exposing the learning algorithms to data poisoning. Attackers can inject malicious data in …

Finite-sample analysis of interpolating linear classifiers in the overparameterized regime

NS Chatterji, PM Long - Journal of Machine Learning Research, 2021 - jmlr.org
