Method Details

runJob

public void runJob()
            throws InterruptedException

Description copied from class: defaultJob

blank function that should be overwritten by class extending bbflow.defaultJob. Here main computation task is done once we're sure there's data in at least one of the input channels Lists 'in' and 'out' must be used manually and EOS() must be managed by the user.

Overrides:

runJob in class defaultJob<SOMData,SOMData>

Throws:

InterruptedException

randomize

void randomize()

normalize

public static ArrayList<Double> normalize(ArrayList<Double> line,
 int depth)

searchBestPosition

public bestPosition searchBestPosition(double[] d_neuron)

learnVector

void learnVector(double[] neuron,
 int i,
 int j,
 double curve)

learnVector

void learnVector(double[] neuron,
 int besti,
 int bestj)

train

private void train(Integer pos1,
 Integer pos2,
 double[] neuron,
 double curve,
 int i,
 int j)
