Hi all am new to Matlab and want guide

1 view (last 30 days)
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

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
