Hello,
I am new to Matlab NN tool box. Presently working with NN.
I have a set of inputs .63 samples with 17 dimensions(17 x 63 ). my o/p is 1 x 63.
Presently i am using nftool for traing the network. I am getting R=1 for training data sets ,but less value for validation data sets and test data. What should i do??
1) is it only trial and error basis and get the correct value of R.
Even if Overall R=0.85 mmre value is going beyond 100%. How can i reduce the mmre.

2) I am getting different results for the same set of P, T and hidden neurons. every time i run.What to do to see that i get the same o/ p always. ??becos i operate now, i get R=0.98, next time i get R0.8
3) Can i use nftool or use any other tool

Thank U
