Subtree Replacement in Decision Tree Simplification

Open access
Ruggieri, Salvatore·2012·Proceedings of the 2012 SIAM International Conference on Data Mining

Abstract

The current availability of efficient algorithms for decision tree induction makes intricate post-processing techniques worth to be investigated both for efficiency and effectiveness. We study the simplification operator of subtree replacement, also known as grafting, originally implemented in the C4.5 system. We present a parametric bottom-up algorithm integrating grafting with the standard pruning operator, and analyze its complexity in terms of the number of nodes visited. Immediate instances of the parametric algorithm include extensions of error based, reduced error, minimum error, and pessimistic error pruning. Experimental results show that the computational cost of grafting is paid off by statistically significant smaller trees without accuracy loss.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
