Method Detail

predict

public int predict(de.jungblut.math.DoubleVector features)

Specified by:

predict in class AbstractTreeNode

Returns:

predicts the index of the outcome, or -1 if not known. In the binary case, 0 and 1 are used to distinguish.

transformToByteCode

public void transformToByteCode(org.objectweb.asm.MethodVisitor visitor,
                                org.objectweb.asm.Label returnLabel)

Description copied from class: AbstractTreeNode

Transforms this node to byte code, given a visitor that already starts containing the methods and a label that must be jumped to in case of a return.

Specified by:

transformToByteCode in class AbstractTreeNode

readFields

public void readFields(java.io.DataInput in)
                throws java.io.IOException

Throws:

java.io.IOException

writeInternal

protected void writeInternal(java.io.DataOutput out)
                      throws java.io.IOException

Description copied from class: AbstractTreeNode

serialize internal state.

Specified by:

writeInternal in class AbstractTreeNode

Throws:

java.io.IOException

getType

public byte getType()

Specified by:

getType in class AbstractTreeNode

Returns:

the byte id of the type: leaf = 1, numerical = 2; nominal = 3
