    Add multiple child nodes to the tree via branchs from node 'n'.

    n

    the parent node

    vc

    the branch value and child node, repeatable

  5. def add(n: Node, v: Int, c: Node): Unit

    Add child node 'c' to the tree via branch 'v' from node 'n'.

    Add child node 'c' to the tree via branch 'v' from node 'n'.

    n

  8. def calcEntropy(nodes: ArrayBuffer[Node] = leaves): Double

    Calculate the entropy of the tree as the weighted average over the list of nodes (defualts to leaves).

    Calculate the entropy of the tree as the weighted average over the list of nodes (defualts to leaves).

    nodes

    the nodes to compute the weighted entropy over

  9. def classify2(z: VectoD): Int

    Given a data vector z, classify it returning the class number (0, ..., k-1) by following a decision path from the root to a leaf.

    Given a data vector z, classify it returning the class number (0, ..., k-1) by following a decision path from the root to a leaf. If no branch found, give maximal decision of current node. Return the best class and its name.

    z

    the data vector to classify

  10. def classify2(z: VectoI): Int

    Given a data vector z, classify it returning the class number (0, ..., k-1) by following a decision path from the root to a leaf.

    Given a data vector z, classify it returning the class number (0, ..., k-1) by following a decision path from the root to a leaf. If no branch found, give maximal decision of current node. Return the best class and its name.
