## Efficient Backprop

Abstract: The convergence of back-propagation learning is analyzed so as to explain common phenomenon observed by practitioners. Many undesirable behaviors of backprop can be avoided with tricks that are rarely exposed in serious technical publications. This paper gives some of those tricks, and offers explanations of why they work. Many authors have suggested that second-order optimization methods are advantageous for neural net training. It is shown that most “classical” second-order methods are impractical for large neural networks. A few methods are proposed that do not have these limitations.

Note: This paper follows the presentation The BackPropagation CookBook given during the NIPS 1996 Workshop Tricks of the Trade organized by Jenny Orr and Klaus-Robert Müller.
