详解sklearn中的make_moons函数

make_moons是函数用来生成数据集,在sklearn.datasets里,具体用法如下:

Parameters:    

n_samples : int, optional (default=100)
    The total number of points generated.
shuffle : bool, optional (default=True)
    Whether to shuffle the samples.
noise : double or None (default=None)
    Standard deviation of Gaussian noise added to the data.
random_state : int, RandomState instance or None (default)
    Determines random number generation for dataset shuffling and noise. Pass an int for reproducible output across multiple function calls. See Glossary.
Returns:    
X : array of shape [n_samples, 2]
    The generated samples.
y : array of shape [n_samples]
    The integer labels (0 or 1) for class membership of each sample.

主要参数作用如下:
n_numbers:生成样本数量
shuffle:是否打乱,类似于将数据集random一下
noise:默认是false,数据集是否加入高斯噪声
random_state:生成随机种子,给定一个int型数据,能够保证每次生成数据相同。
sklearn.datasets.make_moons(n_samples=100, shuffle=True, noise=None, random_state=None)
for example:
X, y = datasets.make_moons(500, noise=0.5)
