Apr 11, 2015 at 19:38 comment added bayerj I beg to differ with what you say. The different local minima arising from symmetries are all of the same quality, so you don't have to worry about that at all. What you probably want to say is that ANNs do not have convex loss functions, which makes optimisation more involved and does not guarantee finding a global optimum. However, there has been quite some evidence recently that ANNs actually do not have that much of local minima issues, but rather saddle point issues. See e.g. arxiv.org/abs/1412.6544.
