Hi,
As far as I know, the neural network pattern recognition tool does not supply the radial basis network algorithm. Is there any RBF neural network function available in Matlab for classification problem?
Many thanks!

Hi - I think the free Netlab toolbox has code for radial basis function networks: http://www1.aston.ac.uk/eas/research/groups/ncrg/resources/netlab/

Yes.
1. Divide the data
2. Normalize or standardize the training set
3. Use the training set statistics (min/max or mean/std) to normalize the trn and val sets.
4. NEWRB does not consider val or tst data. Training stops when either Hmax or MSEtrngoal is reached. I typically use Hmax <= (Ntrn-1)*O/(I+O+1) and MSEtrngoal ~ 0.01*mean(var(t'))
5. Train multiple designs with different values of spread
6. Record the trn/val/tst MSEs and PCTerrs.
7. Choose the design with the best nontraining performance
8. Searching with heath newrb close clear should yield code examples.
Hope this helps.
