'All local minima are global?' ..how about lots of local minima fall below the threshold needed for 100% accuracy ... they are not all global minima, rather only 1 will be?
Consider the function y = |sin(x)|. Lots of local minima, which are all global too. As you said, using accuracy as the loss func doesn't provide enough precision.
