Here I make mode detail investigation to verify the impact of neural net configuration in NS2. There are 16 available neural networks architecture, only Kohonen, PNN and GRRN are not implemented since two of them are used for classification purpose instead of prediction.
I tried to make prediction with all available nets and the minimum average error between 0.0059533 up to 0.0092735,except for GMDH net (applicable for one ouput) giving minimum average error 0.02418.
All results are MSE with 17 inputs and 3 outputs, the result will much better for 17 inputs and 1 outputs. Hence might be better to create 3 neural nets with separate training for 3 outputs prediction instead of one training for 3 nets at once. i will post the result afterward.
I tried to download Neurodimension and make some short prediction using the same data, this software giving minimum MSE at CV and Test are 0.04282 (higher than expected for a commercial software).

What was the input data ?? Is it data what we are using at the moment for MBP ??
(20kbars train/5 kbars test)?
