Perceptron.activate undefined about synaptic HOT 5 CLOSED

it seems that you are not passing any argument to .activate(input) that's why you get Cannot read property '0' of undefined on the line that reads F[1] = input[0];.

Can you provide the code you are using? How do you call the activate method?

i check every input parameter on debugger and all of them was right.

RandomInputSet: (c,max) ->
for i in [0..c] by 1
q = Math.random() * max
@InputSet.push Converter.ToBinary q
Train: ->
while @CurrentIteration < @MaxIteration
q = Math.round Math.random() * @InputSet.length
@Network.activate @InputSet[q]
@Network.propagate @learningrate,@DesiredSet[q]
@CurrentIteration++
console.log @CurrentIteration

Example usage :

@net= new Network "net",8,8,8,8
@net.RandomInputSet 50,100
@net.Train();

Okay, coffeescript is not my strong suit, but I ll do my best. First of all, this line:

@net= new Network "net",8,8,8,8`.

If that's synaptic.Network() then I believe you are providing wrong parameters to the constructor. The Network class expects to receive a layers object, containing an input and output layer, and an array of hidden layers. If what you are trying to do is a perceptron (one input layer with 8 neurons, one output layer with 8 neurons, and 2 hidden layers of 8 neurons each) then you should use the Architect.Perceptron class (see more)

Second thing, and what I believe is causing the undefined input, you are picking inputs from your input set using the following:

q = Math.round Math.random() * @InputSet.length
@Network.activate @InputSet[q] 

That will eventually return a q that's out of the bounds of the inputSet array, since you are using Math.round, instead of Math.floor. Lets say your input set has 50 inputs, then eventually Math.round(Math.random() * 50) will return a value of 50, that will make q be equal to 50 and that will make inputSet[q] be equal to undefined, and that's what causes the activate method to fail with that error.

Simple test:

a = 0;
while(Math.round(Math.random() * 50) != 50) a++;
console.log(a);

Wow i have been fighting with this error for 2 days. I wont use replace all again :D
It wasn't synaptics network parameters seems right now thanks :) If this works it could be huge project and your project is core of it :D

I'm glad i could help and that you find the library useful ^^ and I'm looking forward to see what you come up with!
