Method Detail

initialize

public boolean initialize()

Overrides the initialize() method in the base class. Initializes member data and prepares for execution of first step. This method "resets" the algorithm.

Specified by:

initialize in class Algorithm

Returns:

Returns true.

run

public void run()

Implementation of the run function from the Runnable interface. Determines what the current step is and calls the appropriate method.

Specified by:

run in interface java.lang.Runnable

Specified by:

run in class Algorithm

displayMatrices

public void displayMatrices()

Display two matrices - covariance matrix and the transformation matrix in the text message window

computeDecisionRegions

public void computeDecisionRegions()

Computes the line of discrimination for class independent HLDA

computeErrors

public void computeErrors()

Counts the data points in each set in error and displays them on the text message window

computeHLDA

public void computeHLDA(int fun,
                        int gradfun,
