A Regularized Newton Method for Nonconvex Optimization with Global and Local Complexity Guarantees

NeurIPS 2025poster

Finding an $\epsilon$-stationary point of a nonconvex function with a Lipschitz continuous Hessian is a central problem in optimization. Regularized Newton methods are a classical tool and have been studied extensively, yet they still face a trade‑off between global and local convergence. Whether a…
