Neural Network problem with the goal

Hey everybody maybe someone can help me, with this. What I could do if I put this value in the goal of the net, and the net can't get to this value and stop in validation check net.trainParam.goal=0.01*mean(var(target',1)) What can I do? or I am wrong doing this... I'm a bit lost. Thanks for help me...

For difficult problems, success beyond the default parameter values typically depends on the number of hidden nodes and choice of initial random weights.

Typically I design 100 nets at a time in a double loop configuration with an outer loop of 10 values of hidden nodes Hmin:dH:Hmax and an inner loop with Ntrials = 10 of random initial weights.

Search both NEWSGROUP and ANWSERS for some of my examples using

 greg Hmin:dH:Hmax Ntrials

Hope tis helps

Thank you for formally accepting my answer
