决策树算法的系统实现与修剪优化

决策树是对分类问题进行深入分析的一种方法，在实际问题中，按算法生成的决策树往往复杂而庞大，令用户难以理解，这就告诉我们在重分类精确性的同时，也要加强对树修剪的研究，以一个决策树算法的程序实现为例，进一步讨论了对树进行修剪优化时可能涉及的问题，目的在于给决策树研究人员提供一个深入和清晰的简化技术视图。

Realizing and optimizing of decision tree algorithm

Decision tree is a widely-used solution to classification problems. In many applications, the trees produced are not clear to users due to their size, which tells us that we must notice both accuracy and simplification. Based on an tree-pruning system example , the article further discusses some directions related to pruning the trees, the purpose is to provide researchers with a concise view of pruning technology.
