Federated Incremental Subgradient Method for Convex Bilevel Optimization Problems

Sudkobfa Boontawee, Mootta Prangprakhon, Nimit Nimana

In this letter, we consider a bilevel optimization problem in which the outer-level objective function is strongly convex, whereas the inner-level problem consists of a finite sum…
