Webb13 apr. 2024 · A new paper ‘A deterministic gradient-based approach to avoid saddle points’ by Lisa Maria Kreusser, Stanley Osher and Bao Wang [1] was published recently in the European Journal of Applied Mathematics. It precisely addresses this question of how to modify gradient descent to avoid saddle points. Webb[33] Stanley Osher and Ronald Fedkiw.
