hi,
i am very new to this matlab world..actually my project is about face recognition using neural network..i am pretty much done with it except for the neural network part.i dont know how to check the error and accuracy of the system?mean, i dont know how to get the graphs that show the error and accuracy of the system..after few trials and guidance i managed to get the codes and run the program for it, but when the neural network interface comes out, there is not training done and no iterations and i got this error in the command window...saying out of memory..while my computer still hve 3.5gb free memory..please help me to solve this problem urgently,i need to get this done in two days..please help me thanks alot for any1s help..i m waiting for it eagerly..

regards,
raj

Do you you mean that you don't know how to plot data in Matlab or that you don't know how to extract classification success from you code? If you're "done" with the neural network then presumably you're generating an output which you can use to assess accuracy.

>n the command window...saying out of memory..while my computer still hve 3.5gb

I /think/ you can still get this error if you've asked matlab to perform an operation which will cause it run out of memory,


It's difficult to be of more use given the information provided.

Insufficient information.

How many faces?
How many features per face?
How are inputs and outputs coded?
What type of networks?
How many hidden layers?
How many hidden nodes?
What type of hidden and output activation functions?
How is data partitioned between training, validation and testing?

etc.
