BUG: Machine-Learning-in-Action-Python3/CART_Project3/CART.py

[xiaoliou008]

Machine-Learning-in-Action-Python3/CART_Project3/CART.py
第285行
errorNoMerge = np.sum(np.power(lSet[:, -1] - tree['left'], 2)) + np.sum(np.power(rSet[:, 1] - tree['right'], 2))
中的后半部分rSet的索引似乎应该是[:, -1]。应修改为：
errorNoMerge = np.sum(np.power(lSet[:, -1] - tree['left'], 2)) + np.sum(np.power(rSet[:, -1] - tree['right'], 2))
