how to get fix output for neural network?

hi, i am new to neural network. as i run my program every time different outputs are there.so can any one tell me how to get same output which is best. thanks

In general, weight initialization and data division involve random numbers. Therefore

1. Intialize the RNG to the same state whenever you want to reproduce results.

2. Train in a double loop. I typically use 10 trials for every value of H (number of hiden nodes).

3. Tabulate the results.

4. Find the best result. You can retrain to get the weights by counting how many times the RNG state has changed since initialization.

5. A better generalizing alternative is to find the several best designs and average their outputs. Search the term "ensemble".

Hope this helps.

hello Greg

thanks for your help

will u plz tell me what is RNG? term ensemble?

RNG = random number generator

ENSEMBLE = a combination of neural nets.

Search the term in comp.ai.neural-nets and comp.soft-sys.matlab.

Hope this helps.
