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

1 comment

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))
