    Default :: Doubt Multilayer Perceptron - Weka ::

    Dear sir,

    I am to use Time Series Analysis and Forecasting with Weka and the Algoritm Multilayer Perceptron and I have a fews doubts, can you help me?

    1- How I change the number of nodes of hidden layer?

    2 - The best params for I change is learningRate, hiddenLayers, momentum, epochs, validationThreshold? Can you recommend me a paper that explain this?

    Best Regards,


    Leo

    In the editor dialog for the MultilayerPerceptron there is a button labeled "More" in the "About" field at the top - you can click this to get more information about each of the options. The description for the hiddenLayers option is:

    "hiddenLayers -- This defines the hidden layers of the neural network. This is a list of positive whole numbers. 1 for each hidden layer. Comma seperated. To have no hidden layers put a single 0 here. This will only be used if autobuild is set. There are also wildcard values 'a' = (attribs + classes) / 2, 'i' = attribs, 'o' = classes , 't' = attribs + classes."

    I'd suggest finding a good AI or machine learning book and reading about neural networks.

    Cheers,
    Mark.

    Dear Mark,

    Thanks for your answer,

    I understand how I change the hidden layers, but in Weka I can change the nodes and weight? or only the hidden layers?

    Cheers,

    Leo
