All: I ordered a copy of Profit from BioComp Systems (http://www.biocompsystems.com) last friday and it should be here tomorrow. From what I gather from their website and a few of the links to their customers sites, it looks to be a great package for designing neural nets. The Profit system is an interface to their NeuroGenetic Optimizer (NGO) package that allows you to develop nets that are trained using full trading systems, and are trained by profit rather than accuracy. The NGO features a genetic algorithm that trains a number of nets (the genetic pool) and then evaluates them according to profitability. What this does is force the nets to learn how to make money, rather than minimize errors. It also adjusts all the training settings (ie, network type, momentum rate, etc) automatically, although you can override them if you wish. And the best part about it, and what attracted me to the package most, is that it evaluates all the inputs you feed it, and uses only those of value. The version I ordered allows 64 inputs, which should enable me to dump a number of good indicators in and the net will evaluate which has relevance to the issue I am predicting. This is the most time consuming part of designing a GOOD neural net, and has been what has limited me most with the NS Trader package. NS Trader has a similar setup planned, but it won't shipped until the late summer at the earliest (last I checked with Ward Systems, which was a few months back). I still continue to use NS Trader, but I hope that the Profit system will help shorten the development time when designing new nets. We'll see on Monday I guess! :) Optim
