WitrynaThe thing with saddle points is that they are a type of optimum which combines a combination of minima and maxima. Because the number of dimensions are so large with deep learning, the probability that an optimum only consists of a combination of minima is very low. This means 'getting stuck' in a local minimum is rare. WitrynaIn another post, we covered the nuts and bolts of Stochastic Gradient Descent and how to address problems like getting stuck in a local minima or a saddle point.In this post, …
