Radial Basis Function

Wed, 25 Apr 2012 04:11:39 -0400

Hello,

can anybody explain me how the radial basis function works?

I can configure the parameters MinInfluenceField, MaxInfluenceField and Background, but how do they exaclty influence the radial basis function?

When I look at the theory of the radial basis function there are many different functions that can be used, but I can't find anything about something like a MinInfluenceField, MaxInfluenceField or Background.

And what is the actual basis function used here?

Wrong classification with RProp in neural network demo

Tue, 24 Apr 2012 11:37:24 -0400

Hi all,

am I the only one who gets wrong classifications with the RProp training method in the neural network demo.

In 28% of the cases the classification ist wrong. Backpropagation works fine for me. I attached some screenshots with the wrong classification.

Is this an error in the component or is this normal for RProp?

greetings
Benjamin

General questions about ILKNearestNeighbor

Tue, 10 Apr 2012 08:44:39 -0400

Hi,

I started working with the ILKNearestNeighbor unit. I looked at the wiki and I modified the example to learn a little about its functionality.

I have two questions about ILKNearestNeighbor:
Why is the example not working with k < 6?
Is it possible to change the distance function? Found nothing about that in the wiki...

General Info

Good Day

I know there is not much info on the Intelligence Lab at present but i believe this will be updated soon.

Until then, can anyone recommend some general information on the Neural Network Concept so we have a better understanding when it comes time to do major development.

Any info would be greatly appreciated!

Kind Regards

how to make speech recognition

Sat, 17 Dec 2011 23:56:02 -0500

I will make a speech recognition system the which can
Recognize vowels (A, I, U, E, O), using a backpropagation
neural network system.
I use the components IntelligenceLab 5.0.1 for Delphi, AudioLab 5.0.1 for Delphi and I am using Delphi XE2 program.

I encounter problems when applying it, I use Openwire Editor and
components that I use:
1. ALAudio1 (to take sound from a microphone)
2. ALSpectrum1 (spectrum components)
3. ILNeuralNetworkBackpropTrain1 (backprop training algorithm components)
4. ILNeuralNetwork1 (neural network clasifier)

to the output pins of the component spectrum can I connect with the
input of clasifier neuralnetwork1, but I can not connect the output
spectrum with component input ILNeuralNetworkBackpropTrain1.
My question whether the steps that I am doing is correct or whether
there is still a mistake? or need additional program listings?

greetings Hymae
