**What is network performance and error in sim function of Artificial Neural Network (ANN)**Hi im using ANN as a beginner and having a lot of trouble with it. I am usinng the sim function to test my input . My code is like this
net = newff(ob,obb,hidden_layer_sz, {'radbas' 'radbas'},'traingd','learnlv1' );
net = train(net,ob,obb);
[network_output,garbage_1,garbage_2,error,network_performance]=sim(net,ob,{},{},obb);
It returns network_output and error and network_performance. But i dont understand what does those value stand for. Like I expected network_performance to be between 0 to 1. so that i can understand prediction accuracy fr...

**neural network: Recurrent Neural Networks**Hi Greg and Anders,
thanks for your help of my backpropagation topic. Now I switch to
recurrent neural networks.
My question:
1. Does it the recurrent neural networks need
to divide input data into training, validation and testing 3 sets?
I tried to convert my previous brackpro code into recurrent but it

arguements, which include VV and TV...

**artificial neural network**hi everybody..
this is srikanth.. I am in need of some info about 'nntool'.. I
would like to link this tool to some simulink model. can you please
help me..

hai,
This is BaijuMax,
try to explain u r problem in detail.
Any nntool or neural network related functions very easy to use.
But difficult part is how to design Neural network that best suits u

There many functions for training available .
Type 'doc nnet' to get the matlab help.
If u need further help ,mail me.

**Neural Network Architecture with MATLAB Neural Network Toolbox**Dear neural network experts,
I would like to make a neural network model for a situation
when some of the input variables can interact, while
others don't have any interactions. This information is
based on logical considerations and I have to include it
into the architecture of the net.
For example, I have 3 different groups of input variables.
Within each groups the variables are disjunct (i.e. no
interaction). Variables of different groups may interact.
This would result in either
- restrictions to some weights of a network consisting of
completely inter-linked neurons (i.e. some weight...

**Generalized Regression Neural Networks**hello!
I have started playing with GRNN and have found it to be a good tool.
I've used it for a redundant temperature sensor.
Has anyone else used it with/out success? I haven't been able to find
many papers on it so I'm wondering if it's "passe."
Any insight would be appreciated.
Thanks

**GA+Artificial Neural Network**Hello everybody,
First I would like to ask how can I search the newsgroup archive, if there
is one,
with keywords?
I am doing an turbomachinery optimization with Micro GA program from
Carroll, Cu aerospace
and fitness evaluations are performed with Artificial Neural Networks,
trained using
Navier-Stokes solutions (fluid dynamics).
I have 27 input parameters to be optimized.
The program uses
-tournament selection and binary coding.
I would like to have your opinions on:
1-the appropriateness of micro GA in the first place (population size 10?)
2-relation between the population size and the ...

**General Regression Neural Networks**Hi,
I'm learning neural networks and I have a little trouble understanding the
second layer (summation layer) of the General Regression Neural Networks. Do
I understand correctly that when I want a single output I have two units in
the summation layer:
- The first unit should sum the outputs of the pattern units (RBF-layer).
- The second unit should multiply each output of the pattern unit with the
associated weight?
Sum after multiplication.
Not sure what you mean by "units"
the ouput activation function implements
both operations.
Hope this helps.
Greg.

**Simulating Artificial Neural Network**I have trained a neural network with 7x 600 input data and 8x600 target data matrices using feed forward back propagation(hidden layers 10) method in matlab with nntool.The performance is 0.0249,gradient is 0.00729.After training,simulated the network with the unknown data set of 7x60 . The network divided half of the data (0 0 1 0 0 0 0 0) well and other half it is showing all zero's.I retrained the network and this time some improvement is there.But some of the data are unclassified( 0 0 0 0 0 0 0 0 ).What could be the reason for this ?I f any one knows please share answer.

**Regression problem in neural networks.**Respected Sir/Madam,
I want to calculate the regression through the neural networks. So
plz guide me how to do the same.
Kindly confirm which would be more suitable: Feed forward
backpropagation or GRNN for this.
I have used GRNN to some extent but I am not getting the figure
(graph) which shows the regression line. Therefore, kindly let me
know how to view the GRNN results in graphical form and finally
interpret the results.
With regards.....!

I am developing a Feedforward ANN using the ANN statistical toolbox.

I have normalized my inputs and targets data using the function "mapminmax", after the training i looked into the performance of the training (perf), validation (vperf) and testing( tperf) in the training record and the values are extremely low comapred to these obtained without normalizing the inputs and targets.
My questions are:

Hi,
I'd like to use ANNs in python, especially Simple Recurrent Networks.
Ideally I'd like to find a quick, pythonic module that is able to
simulate different styles of network architectures including some types
of recurrent networks (must: SRN/Elman, may: other recurrent networks
like ESN or LSTM to experiment with them).
So far I found the following Python ANN modules:
- - PyNN (just a builder, requires external simulator) –
http://neuralensemble.org/trac/PyNN/
- - Con-x (part of pyro) – http://pyrorobotics.org/?page=Conx

**Regression**Hello,
I'm trying to create a regression model using the NN toolbox but I can seem to get it.
I have an input matrix X (20x7) with 20 observations and 7 "variables" and an output vector Y with 20 observations too.
So, what I want is simply a vector containing the weights (w) calculated by the NN.
Actually, I want to compare the results with those I've obtained using other regression models.
thanks in advance.
Sergio.

**General Regression Neural Networks #2**Hi,
Being new to GRNNs I'm having trouble in understanding what the weights
should be between the hidden layer and the
output layer?
Basically, the weights between hidden layer and the output layer are
just the output values of the training data (Because there is the same
number of hidden neurons as the number of training data, there is the
same number of weights between the hidden layer and the output layer as
the number of training data too.).

If my application is base on a neural network for recognizing things,
