Reweighting Improves Conditional Risk Bounds

Yikai Zhang, Jiahe Lin, Fengpei Li +4

In this work, we study the weighted empirical risk minimization (weighted ERM) schema, in which an additional data-dependent weight function is incorporated when the empirical risk…

Learning to Abstain From Uninformative Data

Yikai Zhang, Songzhu Zheng, Mina Dalirrooyfard +5

Learning and decision-making in domains with naturally high noise-to-signal ratio, such as Finance or Healthcare, is often challenging, while the stakes are very high. In this pape…
