Saddle Points, Not Local Minima, Are the Real Challenge in High-Dimensional Optimization

burnytech explains that in high-dimensional non-convex landscapes, most critical points are saddle points rather than local minima, a key insight for LLM training. He shares Bengio et al.'s 2014 classic paper and a new video series on how this misconception nearly stalled deep learning.
