A Single-Loop, Constant-Batch First-Order Penalty Method for Stochastic Bilevel Optimization

Xingyu Chen, Ming Yang, Quanqi Hu +1

Recent advances in penalty-based methods for stochastic bilevel optimization (SBO) have eliminated the need for second-order derivative oracles. However, for stochastic nonconvex-s…
