已经提出了各种标准来决定在二叉分类树的给定节点处哪个分割是最好的。想想这个问题。给定一个分裂优度准则和一个节点上的实例的类种群，两个子节点之间的实例的什么分布最大化了分裂优度准则？答案揭示了基尼系数和熵准则之间的有趣区别。
Various criteria have been proposed for deciding which split is best at a given node of a binary classification tree. Consider the question. given a goodness-of-split criterion and the class populations of the instances at a node, what distribution of the instances between the two children nodes maximizes the goodness-of-split criterion? The answers reveal an interesting distinction between the gini and entropy criterion.
