Method Detail

execute

public boolean execute(IMessage content)

Description copied from interface: ICompute

Execute with an incoming message

onlineTraining

public void onlineTraining(double[] x1,
                           double y1)

This method can be used to do the online training Upon the receiving IMessage with a double [] = {y_i, x_i1, ...x_id}

Parameters:

x1 - data point with d elements

y1 - label an integer [-1, +1] for binary classification

batchTraining

public void batchTraining()

This method is used to do batch mode training *

initializeStreamMode

public void initializeStreamMode()

This method can be initialized when constructor is initialized *

initializeBatchMode

public void initializeBatchMode()

This method initializes the parameters needed to run the batch mode algorithm This method is called per a received batch

initializeBinaryModel

@Deprecated
public void initializeBinaryModel(double[][] xy,
                                              int iterations,
                                              double alpha)

Deprecated. must be initialized before main initialization

This method is deprecated and in the new api the model is initialized before job submission

initializeBinaryModel

public void initializeBinaryModel(double[][] xy)

Binary Model is updated with received batch data

Parameters:

xy - data points included with label and features
