generateWRandomWeightvectors
private void generateWRandomWeightvectors()
- Generates random weight vectors, but only for those units that are occupied.
getVectors
public double[][][][] getVectors()
- Description copied from interface:
SOMInputReader
- Returns a 4-dimensional double array of the weight vectors. The first dimension represents units of a map in
horizontal direction, the second dimension represents the units of a map in vertical direction and the third
dimension represents units of a map in depth.
- Specified by:
getVectors
in interface SOMInputReader
- Overrides:
getVectors
in class AbstractSOMInputReader
- Returns:
- a 4-dimensional double array of the weight vectors.
getNrVecMapped
public int getNrVecMapped(int x,
int y,
int z)
- Description copied from interface:
SOMInputReader
- Returns the number of vectors mapped onto a certain unit specified by coordinates
x
and
y
. If the coordinates are invalid, an ArrayIndexOutOfBoundsException
will be thrown.
The calling function is not obliged to catch it.
- Specified by:
getNrVecMapped
in interface SOMInputReader
- Overrides:
getNrVecMapped
in class AbstractSOMInputReader
- Parameters:
x
- horizontal position of the unit on the map.y
- vertical position of the unit on the map.z
- TODO
- Returns:
- the number of vectors mapped onto a certain unit specified by coordinates
x
and
y
.
getMappedVecs
public String[] getMappedVecs(int x,
int y,
int z)
- Description copied from interface:
SOMInputReader
- Returns an array of strings containing the names of vectors mapped onto a certain unit specified by coordinates
x
and y
. If the coordinates are invalid, an ArrayIndexOutOfBoundsException
will be thrown. The calling function is not obliged to catch it.
- Specified by:
getMappedVecs
in interface SOMInputReader
- Overrides:
getMappedVecs
in class AbstractSOMInputReader
- Parameters:
x
- horizontal position of the unit on the map.y
- vertical position of the unit on the map.z

coordinates
x
and y
. If the coordinates are invalid, an
ArrayIndexOutOfBoundsException
will be thrown. The calling function is not obliged to catch it.
- Specified by:
getMappedVecsDist
in interface SOMInputReader
- Overrides:
getMappedVecsDist
in class AbstractSOMInputReader
- Parameters:
x
