一种有效的决策树交叉验证算法

Efficient algorithms for decision tree cross-validation

Hendrik Blockeel, Jan Struyf

摘要:

交叉验证是机器学习中经常采用的有用且普遍适用的技术,包括决策树归纳。直接实现该技术的一个重要缺点是其计算开销。在本文中,我们表明,对于决策树,交叉验证的计算开销可以显着降低集成的交叉验证与正常的决策树归纳过程。我们将讨论如何现有的决策树算法可以适应这一目标,并提供这些适应可能产生的加速比的分析。实验结果支持了分析。

英文摘要:

Cross-validation is a useful and generally applicable technique often employed in machine learning, including decision tree induction. An important disadvantage of straightforward implementation of the technique is its computational overhead. In this paper we show that, for decision trees, the computational overhead of cross-validation can be reduced significantly by integrating the cross-validation with the normal decision tree induction process. We discuss how existing decision tree algorithms can be adapted to this aim, and provide an analysis of the speedups these adaptations may yield. The analysis is supported by experimental results.
