New block-Lp estimators offer robust machine learning for corrupted data

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new family of block-Lp estimators for robust machine learning, particularly effective with heavy-tailed and adversarially corrupted data. These estimators, derived from a deterministic optimization perspective, offer improved robustness constants compared to existing convex block M-estimators. The study introduces a nonconvex block-Lp family for p between 0 and 1, demonstrating that its global minimizers approach the trimmed-block oracle constant as p decreases, while maintaining a benign optimization landscape.

    Median-of-Means as an Extremal Convex Estimator and a Nonconvex Route to the Trimmed Oracle

    arXiv:2609.01689v1 Announce Type: new Abstract: We revisit median-of-means estimation from a deterministic optimization viewpoint and develop a family of block-Lp estimators for robust learning with heavy-tailed and adversarially corrupted data. In a block contamination model wit…
