If used together with pruning, early stopping may save time.

2 rowsNov 01, Post-pruning will result in the generation of a set of sub-trees, each with a performance Cited by: The decision tree (DT) induction process has two major phases: the growth phase and the pruning phase. The pruning phase aims to generalize the DT that was generated in the growth phase by generating a sub-tree that avoids over-fitting to the training data.

Most post-pruning methods essentially address post-pruning as if it were a single objective problem (i.e. maximize validation accuracy), and Cited by: Request PDF Post-Pruning in Decision Tree Induction Using Multiple Performance Measures The decision tree (DT) induction process has two major phases: the growth phase and the pruning Estimated Reading Time: 10 mins.

No. 11 Post-pruning in decision tree induction using multiple performance bushmulching.bar by: Feb 01, Post-pruning will result in the generation of a set of subtrees, each with a performance vector v k = (v k1, v k2, v k∣J∣) where v kj is Sub_RT k ’s score with regards to performance measure j, and J is the index set of the performance measures.

Since each subtree has multiple performance measures then the problem of selecting the most appropriate subtree is in fact a multiple criteria. K. M. Osei-Bryson, “Post-Pruning in Decision Tree Induction Using Multiple Performance Measures” Computers & Operations Research, Vol.

34, No. 11,pp. Feb 16, Post-pruning is also known as backward pruning. In this, first generate the decision tree and then r e move non-significant branches. Post-pruning a decision tree implies that we begin by Estimated Reading Time: 3 mins.

Early stopping and pruning can be used together, separately, or not at all. Post pruning decision trees is more mathematically rigorous, finding a tree at least as good as early stopping. Early stopping is a quick fix heuristic. If used together with pruning, early stopping may save time.
