for those who are familiar with FANN you will find a very interesting article HERE I think Emsi, the one who wrote the article have done a very good job

enjoy it

As to using RIPPER you don't have to implement it in MQL language. Just extract the rules and code them in MQL /you'll get a set of simple IF [...] THEN [...] ELSE [...] rules/. This way you can use J-REP, a Java based implementation of RIPPER /i think it's part of WEKA framework/.

I personally have an implementation of RIPPER in C, which I got from William Cohen [the author of RIPPER], but I can't share it without his permission. You might try emailing William and asking him for a copy of RIPPER implementation - he's a nice guy and should help you.

Some general info about decision trees and pseudo code of RIPPER can be found here

Have a look at Chapter 9.

Hi Kazam,

Do you know or do you have any experience with FURIA: Fuzzy Unordered Rule Induction Algorithm?(Experimental results show that FURIA significantly outperforms the original RIPPER, as well as other classifiers such as C4.5, in terms of classification accuracy.)

I've heard about FURIA and read 2 or 3 white papers about it but I don't have any experience using it. It's based on RIPPER and the results aren't a lot better so I just added it to my "to do" list for later.

Just checking,
is it that all EA's ultimatley result in a loss over time?
Is there like an EA Junk yard where traders with new ideas can tinker an probably inprove the performance of current poor performers (that were once profitable).

It would be nice to see what an EA with a - 1 expectancy does to an account. this seems the likely effect of an EA designed to optimize itself and no longer can adapt to current conditions.

If you have your discarded EA and they can be optimized, please share same , one never knows fron where the next theory on relativity might emerge.

Peace.
