org.dllearner.algorithms.celoe.OENode

All Implemented Interfaces:

SearchTreeNode

public class OENode
extends AbstractSearchTreeNode<OENode>
implements SearchTreeNode

A node in the search tree of the ontology engineering algorithm. Differences to the node structures in other algorithms (this may change): - covered examples are not stored in node (i.e. coverage needs to be recomputed for child nodes, which costs time but saves memory) - only evaluated nodes are stored - too weak nodes are not stored - redundant nodes are not stored (?) - only accuracy is stored to make the node structure reusable for different learning problems and -algorithms
