Bill, as a matter of fact I believe that Neurostock can do that, but you have to purchase the Genetic Algorithm model. If your interested in another program that uses Genetic Algorithms, you can download a shareware program called NGO. Essentially you build the nets from scratch, preprocess the information, set the parameters, and it will kick out the best ten nets it finds, usually in less than a few hours for some simple nets. Both Jay and I experimented for a few months with it. The kicker is that the best nets ( the fittest) are not necessarily the most accurate, and no matter what I tried I was never satisfied with the results. Jay even experimented with inputting the those weighted inputs you mentioned into his Neurostock models, but I don't think the experiment was successful. He can tell you more about that than I can.
Having given NGO more than a fair chance, I really appreciate the relative simplicity, and accuracy of Neurostock.
According to an article I read, while memorizing the data is a consideration, most current programs have safeguards to minimize that possibility. |
