Nissman) Newsgroups: comp.ai.neural-nets Subject: Conjugate Gradient methods for feedforward nets Keywords: backprop,quickprop,training algorithms Message-ID: <4028@rtifs1.UUCP> Date: 22 Aug 90 19:06:17 GMT Distribution: comp Organization: Research Triangle Institute, RTP, NC Lines: 11 I would like a pointer to the application of the conjugate gradient method to training feedforward networks. A symbolic description of how to actually implement this method in such a network would be greatly appreciated. Also, how does this differ from Fahlman's Quickprop algorithm? Pros and cons of using one method over another would be desireable as well. A related question is: which of these methods works best in scale-up problems and why? Many thanks, Daniel Nissman
