Hi all am new to Matlab and want guide

Hi all I want to create Neural network optimized by GA

but I totaly donot know anything about matlab

so I will tell all the steps and tell me what to read to make full understanding, I will use it in financial analysis so

I will have 12 variables want use GA to get the Best of them so I can make the new model

which will test it with NN optimized by GA and Although by BAckpropagtion

so my Questions

1- how use GA to optimize my variables selection? What to read?and how to input the values?

2- how to Train NN to be used using GA?? what to read and how to input the values?

If you have a choice, do not use GA to train NNs if you are not familiar with NNs.

There are no good examples for reference. A search of the NEWSGROUP and ANSWERS using

 neural GA

and

 neural genetic

doesn't help much.

If you do not take my advice and have trouble with your code, post it and someone may be able to help.

There is a matlab manual

However, all of the matlab documentation with examples is online at mathworks.com

Most of the matlab documentation with examples is available from the command line. Just type the command

 doc

or for specific function documentation use the help command first

 help fitnet        % regression and curve-fitting
 doc  fitnet
 help patternnet    % classification and pattern-recognition
 doc  patternnet
 help narxnet        % timeseries prediction
 doc  narxnet

essam's "Answer" moved here since it's not an answer to the original question:

thanks a lot for your answer, what you recommend me to do about NN training? is there a better algorithm?

I am Zero knowledge in matlab, all what I know is matlab NN toolbox and GA toolbox

so, can recommend me a tutorial to start to make my code? and what recommendation about NN training algorithm? although many literature research proved its accuracy

[Greg Heath]

Your questions are too vague.

1. Start with the examples in the HELP and DOC documentation (see above).

2. Additional example data is available using the commands

 help nndatasets
 doc nndatasets

3. It will be easier to get help using the above data.

4. Then you can try it on your data.

I have posted zillions of examples in the NEWSREADER and ANSWERS.

Notice that I CANNOT RECOMMEND using GA for designing NNs.

Hope this helps,

Greg
