了解Softmax概率

Question

给定以下Softmax回归模型，此实例属于裸土类的概率是多少？

Answer 1

如果我没理解错你的问题，这是你需要计算概率的方法：

import numpy as np
d = {"vegetation": 0.3, "bare soil": 0.1, "impervious": 0.1}

P_baresoil = np.exp(d["bare soil"]) / np.sum(np.exp(list(d.values())))
P_vegetation = np.exp(d["vegetation"]) / np.sum(np.exp(list(d.values())))
P_impervious = np.exp(d["impervious"]) / np.sum(np.exp(list(d.values())))

P_baresoil = 0.31
