Sever: A Robust Meta-Algorithm for Stochastic Optimization
international conference on machine learning, 2018.
In high dimensions, most machine learning methods are brittle to even a small fraction of structured outliers. To address this, we introduce a new meta-algorithm that can take in a base learner such as least squares or stochastic gradient descent, and harden the learner to be resistant to outliers. Our method, Sever, possesses strong theo...More
