Constructor Detail

SotaHelper

public SotaHelper(DataArray rowContainer,
                  ExecutionMonitor exec)

Constructor of SotaHelper, which sets the given rowContainer with the training data.

Parameters:

rowContainer - DataArray with the training data

exec - the ExecutionMonitor to set.

Method Detail

getRowContainer

public DataArray getRowContainer()

Returns the DataArray with the training data.

Returns:

the DataArray with the training data

getDimension

public int getDimension()

Returns the dimension.

Returns:

the dimension

setDimension

protected void setDimension(int dimension)

Sets the given dimension.

Parameters:

dimension - dimension to set

initializeDimension

public abstract int initializeDimension()

Returns the number of a specific type of DataCells in a RowContainers row. What specific type of DataCells can be specified in the concrete implementation (i.e. Fuzzy or Number).

Returns:

the number of a specific type of DataCells

initializeTree

public abstract SotaTreeCell initializeTree()
                                     throws CanceledExecutionException

Initializes the Sota tree with specific SotaCells like SotaFuzzyCell or SotaDoubleCell. Which kind of SotaCell is used is specified in the concrete implementation.

Returns:

the initialized tree with a ancestor node and two children cells

Throws:

CanceledExecutionException - if execution was canceled.

adjustSotaCell

public abstract void adjustSotaCell(SotaTreeCell cell,
                                    DataRow row,
                                    double learningrate,
                                    String cellClass)

Adjusts the given SotaTreeCell related to the given DataRow and learningrate and assigns the given class.

Parameters:

cell - cell to adjust

row - row to adjust the cell with

learningrate - learningrate to adjust the cell with

cellClass - The class to assign to the cell.

getExec

protected ExecutionMonitor getExec()

Returns:

the ExecutionMonitor

setExec

protected void setExec(ExecutionMonitor exec)

Parameters:

exec - the ExecutionMonitor to set
