Achieving $O (I^µ^{- 1.5})$ Complexity in Hessian/Jacobian-free Stochastic Bilevel Optimization

Yifan Yang, Peiyao Xiao, Kaiyi Ji

In this paper, we revisit the bilevel optimization problem, in which the upper-level objective function is generally nonconvex and the lower-level objective function is strongly co…
