    12/13/16 | An empirical analysis of deep network loss surfaces.
    Im DJ, Tao M, Branson K
    arXiv. 2016 Dec 13:arXiv:1612.04010

    The training of deep neural networks is a high-dimension optimization problem with respect to the loss function of a model. Unfortunately, these functions are of high dimension and non-convex and hence difficult to characterize. In this paper, we empirically investigate the geometry of the loss functions for state-of-the-art networks with multiple stochastic optimization methods. We do this through several experiments that are visualized on polygons to understand how and when these stochastic optimization methods find minima.
