Method Detail

setWeights

public static Vector setWeights(int type,
                java.lang.String path)

Set weights for a model from a given file This function either sets the new vector to be zeros or reads the data from a given path

Parameters:

type - - if this parameter is set to be 0 than the returned vector will be zeros, if 1 than it will populate the vector with the file's data

path - - the path to the file that contains the vecotr's data

Returns:

the new vector

convert2Weights

public static Vector convert2Weights(java.util.ArrayList<java.util.ArrayList<java.lang.String>> data)
                              throws java.text.ParseException

Converts an array list of strings into a vector of double this function can be used after reading a vector from a file

Parameters:

data - the data 2D array but we treat tim as a 1D array

Returns:

a vector that contains the model weights

Throws:

java.text.ParseException

randomShuffle

public static InstancesContainer randomShuffle(InstancesContainer instances)

preforming random shuffle on the data instances

Parameters:

instances -

Returns:

printMul

public static java.util.HashMap<java.lang.Integer,java.lang.Double> printMul(Vector v1,
                                                             Vector v2)

sortMul

public static java.util.TreeMap<java.lang.Integer,java.lang.Double> sortMul(Vector v1,
                                                            Vector v2)
