I am using Matlab R2012 and wish to design BPNN. Using nprtool, it is possible to design a two layer backpropagation neural network. I have following query:
Can backpropagation neural network using patternnet take the non-Binary dataset as a training set? please guide me. Thank you in advance.

For a c-class classifier, use patternnet with binary targets consisting of columns of the c-dimensional unit matrix eye(c).
Inputs can be real or binary.
There are many examples available. Search

There are 3 main ways to improve generalization. Although they can be used simultaneously, usually one is sufficient.
1. Given a training goal, e.g.,
NMSE = mse(error)/mean(var(target',1)) <= 0.01
Minimize the number of hidden nodes
2. Use a validation stopping subset
3. Use regularization via
a. MSEREG
or
b. TRAINBR
Hope this helps,
Greg
