A Fast and Simple Modification of Newton’s Method Avoiding Saddle Points
Journal of Optimization Theory and Applications, Jul 2023 We propose in this paper New Q-Newton’s method. The update rule is conceptually very simple, using the projections to the vector subspaces generated by eigenvectors of positive (correspondingly negative) eigenvalues of the Hessian.
