DESIGNING AN ELMAN NET PROJECT

A MATLAB Central Contributor Question Sent On:Feb 02/03/16 11:26 PM

Hi Greg, I'm in a senior semester at university and our senior project is about neural network by matlab and my mission is elman back propagation neural network, but unfortunately, I don't know any thing about it. can you help me please?

1. Start with the command line help and doc documentation

    lookfor elmannet
    help    elmannet
    doc     elmannet

2. I am satisfied when

   a. the mean-square-error  mse(target-output) is at least 100 times 
       smaller than the mean-target-variance mean(var(target',1))
   b. the total number of weights net.numWeightElements is as small 
      as possible

3. Run the help and doc examples

     a. Use defaults on 10 examples (Ntrials = 10, for i=1:Ntrials ...), 
         with different random initial weights 

     b. See if the number of hidden nodes can be reduced without 
         violating 2a

     c. See if increasing the number of feedback delays makes a 
         significant difference

3. For references search

                answers   mathworks   newsgroup   

   elman           22         26        51      

   elman greg      11         11        16

4. Post an attempt on one or more of the other time-series example datasets from

   help nndatasets
   doc nndatasets  

 Hope this helps.

What is the question here?

[Greg Heath]

@John

I interpreted the question to be

 How do I design and use an ELMAN net?

 OH! ...

Did you think I should have posted this in the NEWSGROUP instead?

If I were you, I would send via contact option in profile.

[Greg Heath]

I make it a rule to only contact requesters via the NEWSGROUP or ANSWERS. However, the subject has to be the type that I usually consider on those groups.
