NumPy是Python专用于矩阵计算的包,底层函数主要用C语言编写。NumPy还是众多数据处理包的基石,比如 pandas 和 Sciki-Learn。 可见,想学好Python数据分析和机器学习,必须掌握NumPy。 我们先比较下NumPy和Python传统的数据运算,看两者的效率差别。 import numpy as np import time ## 列表运算 start = time.time() #...
在这里,M是类的数量(setosa、versicolor 和 virginica),y是类标签c是否正确的 0 或 1,p是观测值o属于类c的预测概率。您可以在 ml-cheatsheet 网站上了解更多关于不同损失函数和度量的信息,网址为ml-cheatsheet.readthedocs.io/en/latest/loss_functions.html。 另请参见 您可以在每个库的网站上找到本教程中使用...
