Method Detail

getParentIndex

public abstract int getParentIndex()

Returns:

Index of node's parent

getLeftChildIndex

public abstract int getLeftChildIndex()

Specified by:

getLeftChildIndex in interface ai.h2o.algos.tree.INode<FVec>

Returns:

Index of node's left child node

getRightChildIndex

public abstract int getRightChildIndex()

Specified by:

getRightChildIndex in interface ai.h2o.algos.tree.INode<FVec>

Returns:

Index of node's right child node

getSplitCondition

public abstract float getSplitCondition()

Returns:

Split condition on the node, if the node is a split node. Leaf nodes have this value set to NaN

getLeafValue

public abstract float getLeafValue()

Specified by:

getLeafValue in interface ai.h2o.algos.tree.INode<FVec>

Returns:

Predicted value on the leaf node, if the node is leaf. Otherwise NaN

default_left

public abstract boolean default_left()

Returns:

True if default direction for unrecognized values is the LEFT child, otherwise false.

getSplitIndex

public abstract int getSplitIndex()

Specified by:

getSplitIndex in interface ai.h2o.algos.tree.INode<FVec>

Returns:

Index of domain category used to split on the node
