A path in a binary tree is a sequence of nodes where each pair of adjacent nodes in the sequence has an edge connecting them. A node can only appear in the sequence at most once. Note that the path does not need to pass through the root. The path sum of a path is the sum of t...
Gini(D) = 1- \sum_{i=1}^{m}{P_i}^2 对于每一个子集,要么属于(D1),要么不属于(D2),所以计算结果如下: Gini_A(D) = \frac{|D_1|}{|D|}*Gini(D_1) + \frac{|D_2|}{|D|}*Gini(D_2) 同理可以计算出该特征下面每个子集的Gini指标,按同样的方式还可以计算其他每个特征下面每个子集...
