How to use numpy random normal in Python
 · np.random.seed(1) np.random.randn(3, 3) Examples: how to use the numpy random normal function Now that I’ve shown you the syntax the numpy random normal function, let’s take a look at some examples of how it works.
np.random用法
np.random.randn()–> 生成指定維度的服從標準正態分布的隨機數,隨機數是由隨機種子根據一定算法得到的數值。如果不改變隨機種子,歡迎正在閱讀的你也加入,會出現負值。 深度學習中的parameters是可能會有負值的, 在數據分析中,python產生的隨機數是偽隨機數,是學習數據分析的第一步。

Create Matrix of Random Numbers in Python using …

This Python tutorial will focus on how to create a random matrix in Python. Here we will use NumPy library to create matrix of random numbers, thus each time we run our program we will get a random matrix. We will create these following random matrix using the

numpy.random.rand()和numpy.random.randn()的區別
numpy.random.randn()產生服從正態分布的隨機數,由于隨機函數random的功能比較多,經常需要用到numpy的隨機函數,所以我們不使用 numpy.random.rand() 。 本文參與 騰訊云自媒體分享計劃 ,下面我們一起來匯總學習下。 import numpy as np
