A Regularized Newton Method for Nonconvex Optimization with Global and Local Complexity Guarantees
NeutralArtificial Intelligence
A recent study introduces a regularized Newton method aimed at solving the challenges of nonconvex optimization, particularly in achieving both global and local convergence. This method addresses the longstanding issue of balancing these two aspects, which is crucial for optimization tasks in various fields. The research is significant as it explores whether a parameter-free algorithm can meet the optimal global complexity while ensuring quadratic local convergence, a question that has yet to be resolved in the optimization community.
