Example 1 with TreeNodeBitCondition

use of org.knime.base.node.mine.treeensemble.model.TreeNodeBitCondition in project knime-core by knime.

the class TreeBitVectorColumnData method updateChildMemberships.

/**
 * {@inheritDoc}
 */
@Override
public void updateChildMemberships(final TreeNodeCondition childCondition, final double[] parentMemberships, final double[] childMembershipsToUpdate) {
    TreeNodeBitCondition bitCondition = (TreeNodeBitCondition) childCondition;
    assert getMetaData().getAttributeName().equals(bitCondition.getColumnMetaData().getAttributeName());
    final boolean value = bitCondition.getValue();
    for (int i = 0; i < m_length; i++) {
        if (m_columnBitSet.get(i) != value) {
            childMembershipsToUpdate[i] = 0.0;
        } else {
            assert childMembershipsToUpdate[i] == parentMemberships[i];
        }
    }
}

Example 2 with TreeNodeBitCondition
