public int L

Constructor Detail

Trellis

public Trellis(int[] indicies,
               int WIDTH,
               int conectivity)

Trellis

public Trellis(int[] indicies,
               int[][] trellis,
               int WIDTH,
               int conectivity)

Method Detail

toString

public String toString()

Overrides:

toString in class Object

swap

public void swap(int j,
                 int k)

putTogether

public void putTogether(int j,
                        int k)

weight

public double weight(weka.core.Instances D)

weightNeighbourhood

public double weightNeighbourhood(int j)

weight

public double weight(int[] indices,
                     int j,
                     int j_,
                     double[][] I)

What would the 'score' be, putting j_ at position j, in indices, with I matrix.

getNeighbours

public int[] getNeighbours(int j)

Get the neighbouring variables of a given index. For example, 4 1 2 5 3 0 getNeighbours(3) = [2,1,0] // if TYPE = 1 getNeighbours(3) = [4,2,1,0,3] // if TYPE = 2 getNeighbours(3) = [] // if TYPE = 0

Parameters:

j - an index

Returns:

neighbouring variables of index k NOTE: takes an index, returns variables -- A BIT STRANGE -- should return indices also

make

public void make()
