Numpy 是 Python 中的一个模块,主要用于处理数学和计算相关的问题,这里是一个入门的介绍。 导入 习惯上可以这样导入: import numpy as np 在machine learning in action 这本书里,是没有as np的: from numpy import * 两种方式都可以,看习惯吧。 随机数 生成一个 4 * 4 的随机数组(0<元素<1): np.rand...
# In this way, we are basically saying: the weight is 13 and the bias is 2. targets = 13*x + 2 + noise # Check the shape of the targets just in case. It should be n x m, where n is the number of samples # and m is the number of output variables, so 1000 x 1. print ...

Python is a general-purpose computation language, but it is very welcomed in scientific computing. It can replace R and Matlab in many cases, thanks to some libraries in the Python ecosystem. In machine learning, we use some mathematical or statistical functions extensively, and often, we will...
