These days I apply a FITNET to design my own predictive controller. Indeed, it is very convenient to use. However, there is little concrete content about the structure of this net in the MATLAB documentation. Could someone answer me these sub-questions: (1) Is it similar to a traditional BP net? And what is the difference between them, activation functions? (2) If it has the same structure as the BP net, why is it named FITNET? The 'Tips' in the documentation informs that "Function fitting is the process of training a neural network on a set of inputs in order to produce an associated set of target outputs." Does it mean the FITNET just adopts a new way to train a BP net?

FITNET is the default net for curveFITting and regression.

It is the standard configuration that comes to mind whenever anyone says

NEURAL NETWORK

for details use the commands

 help fitnet
 doc fitnet

and

type fitnet

For classification or pattern recognition the default is PATTERNNET.

CLARIFICATION:

If you run the code in the

help fitnet

and

doc fitnet

you will see the circuit diagrams.

FITNET is a standard MLP with one hidden layer and a linear layer output. It is used for curve"fit"ting and regression.

PATTERNNET is a standard MLP with one hidden layer and a binary layer output. It is used for classification and "pattern" recognition.

Thank you for formally accepting my answer

Greg

Thanks, standard MLP is what I want.

Hey Greg, can you please tell somthing on default activation function used in FITNET? Thanks.
