case class Node(f: Int, gn: Double, nu: VectoI, parent: Node = null, y: Int, isLeaf: Boolean = false) extends Cloneable with Product with Serializable
The Node class is used to hold information about a node in the decision tree.
- f
the feature/variable number used for splitting (negative => leaf)
- gn
the information gain recorded at this node
- nu
the frequency count
- parent
the parent node (null for root)
- y
the response/decision value
- isLeaf
whether the node is a leaf (terminal node)
