Artificial Neural Network UDF

You need to train a neural net on data, using this code:

#include "_Fann.au3"

Global $InputsArray[4][2] = [[-1, -1],[-1, 1],[1, -1],[1, 1]]
Global $OutputsArray[4][1] = [[-1],[1],[1],[-1]]
Local $ANNLayers[3] = [2, 3, 1]
_InitializeANN()
$Ann = _CreateAnn(3, $ANNLayers)
_ANNSetActivationFunctionHidden($Ann, $FANN_SIGMOID_SYMMETRIC)
_ANNSetActivationFunctionOutput($Ann, $FANN_SIGMOID_SYMMETRIC)
_ANNTrainOnData($Ann, $InputsArray, $OutputsArray, 5000, 10, 0.001)
_ANNSaveToFile($Ann, "xor_float.net")
_DestroyANN($Ann)
_CloseANN()

The ANN being created has 3 layers, 2 input, 3 hidden, and 1 output neuron.

For my example, you need to create a neural network with 3 layers, 24 inputs in the first one, 12 hidden neurons, and 11 outputs. The training data is saved into .data files, the networks into .net. It looks like you tried to load the training data as a network.

I've got it .I mixed between mousepatterns.net and mousepatterns.data

Thanks!

I tried to make an example that learn division but is not working, anyone a little help?

#include <_Fann.au3>

Dim $INPUT[5][2] = [[2,1],[8,4],[12,3],[5,2],[9,1.5]]
Dim $OUTPUT[5][1] = [[2],[2],[4],[2.5],[6]]
Local $LAYER[3] = [2, 3, 1]

_InitializeANN()
$ANN = _CreateAnn(3,$LAYER)
_ANNSetActivationFunctionHidden($ANN, $FANN_SIGMOID_SYMMETRIC)
_ANNSetActivationFunctionOutput($ANN, $FANN_SIGMOID_SYMMETRIC)
_ANNTrainOnData($ANN,$INPUT,$OUTPUT, 15000, 1000,0.001)
_ANNSaveToFile($ANN, "num_div.net")
_DestroyANN($ANN)
_CloseANN()

Dim $CALC[2] = [4,1]
_InitializeANN()
$ANN = _ANNCreateFromFile("num_div.net")
$RESULT = _ANNRun($ANN,$CALC)
MsgBox(0,"Division", $CALC[0] & " / " & $CALC[1] & " = " & $RESULT[0])
_DestroyANN($ANN)
_CloseANN()

Looks interesting but every time when I run some of the scripts here it doesn't work.

C:\Program Files\AutoIt3\Include\_Fann.au3 (48) : ==> Subscript used with non-Array variable.:
Return $hAnn[0]
Return $hAnn^ ERROR

@Andreik, try different numbers of neurons and hidden layers between your inputs and outputs, it could be that the relation you're trying to model is more complex than can be represented with just 3 neurons. It will take some trial and error, but I think it can be done. Maybe try 2 hidden layers with 4 neurons each?

Local $LAYER[3] = [2, 4, 4, 1]

@Jjo, the include folder isn't for scripts that you download, that's used for core AutoIt includes. Put _Fann.au3 in the same directory as the script you're trying to use, and do #include "_Fann.au3".

The error is meaningless without knowing what script you're running, what directory the dll is in, and so on. So, let me know more information.

Ok that worked, thanks.

Wow! Really great stuff!

Thank you for sharing!

Its stilll not working for me...I am also getting the same error as that of jijo. The udf, the dll file and the example file is in the same directory still it is not working. plz help..!!

Wow, This is spectacular. I've always seen in AutoIt's AI department great potential, but this exceeds all expectations.

Been working on AI's for a while now and i can say just by looking a this, that it will speed up my work exponentially.

I give my thanks.

any more info from ppl using this? its interesting topic.

cant download fannfloat.dll! Please help

First my appology for resurecting this thread. But I'm curious, and someone monitoring this thread from way back might have good answers.

1: Does anyone use FANN (with autoit) these days?

2: Does anyone use it on win64? To me it looks like a wraper to handle pointers to structs are needed between the library and AutoIt?

3: Is there any other Neural Network Library in use with AutoIt?
