Hello All,

I am using Neural Network tool box for function approximation
problems. I am ussing the newff and newrb nets. The problem with me
is I have few training data sets (only 12). Can any one suggest a
method to improve the genaralizing ability of t >> more

I am using the newrb function in Matlab to create a radial basis function
neural network. A radial basis network typically consist of two layers: a
hidden radial basis layer and an output linear layer.

I am trying to use this to create a classifier ( >> more

??? Error using ==> newrb
Inputs and Targets have different numbers of columns.

Is there any way to validate the network when using radial basis
function. It looks to me that standard functions newrb and newrbe
does not support validation.

I am using RBF neural network for classification.i use "NEWRB"
function for building a RBF network.but my input vector are so large
and when i want to train my computer hangs and don't respond.
is there any way to solve this problem?

I'm trying to classify a 144 x 57 matrix where the 144 is the class
(i.e. i want to classify the data into the 144 types).

Upon looking at newrb, it seems that the output matrix has the same
number of columns as the input.

Am I right to place >> more

I was wondering how the training algorithm in MATLAB behaves when a
layer of the network contains a hand-coded(not using newrb)radial
basis layer, does any one know how to train a radial basis function?

I'ts not clear What is the algorith used in "NEWRB.M" NN toolbox
In terms of learning.
It is Orthogonal least square, k-means, knn, other?

The newrb function in nnet toolbox is used. The input is a matrix with
the size of 10x9000. That is to say, each input vector is 10 dimensional
and there are 9000 inputs. The size of the output is 2x9000. Both the
inputs and the outputs have been normaliz >> more

With plot, I can tell it to plot on a specific axes by specifying an axes
as the first argument.

Is there a way to do the same thing with plotyy? I'm doing this inside a
GUI in the event that it matters...
