Feature Selection for Huge Data via Minipatch Learning

no code implementations16 Oct 2020 Tianyi Yao, Genevera I. Allen

While feature selection is a well-studied problem with many widely-used techniques, there are typically two key challenges: i) many existing approaches become computationally intractable in huge-data settings with millions of observations and features; and ii) the statistical accuracy of selected features degrades in high-noise, high-correlation settings, thus hindering reliable model interpretation.
