Math Issues: Optimizing With Multiple Peaks Or Valleys



A problem with gradient descent optimization is that it can find minima of functions as well as maxima of functions. Worse, there can be multiple peaks and valleys, so more properly gradient descent find local extrema. One is interested in machine learning, e.g., in global minima. This makes the problem considerably more difficult.
