Contaminated Multi-task Learning with Heterogeneity: Fundamental Limits and Optimal Algorithms

Ye Tian, Mengchu Li, Marco Avella Medina

Integrating information across related tasks can improve estimation and prediction in transfer, multi-task, and federated learning, but contamination and heterogeneity make robust borrowing challenging. We study a contaminated multi-task empirical risk minimization (ERM) framewor…Read more
