Neuralnet node output

Question

Hello,

Is there any way that I can get the output of each node (the result of the activation function) for each instance that goes through the Neuralnet or other Multilayer Perceptron type algorithm using RapidMiner API?

Thank you in advance,

João Guerreiro

Hi João, 
Can you please mention the method you used to calculate the output from the input variables and weights? It would be a great help as I'm struggling to do this and I can't reproduce the NeuralNet output manually. Thanks

Thank you Sebastian,

I did it myself, using the result from the weights and the input values, I calculated the output for each node.

Cheers,

Hi,
as far as I know, this is not possible. Since it is a very unusual goal, it is not supported by the rapidminer gui. But RapidMiner itself uses the open source library joone for the neural net calculation. Perhabs there's a possibility to hook in.
