It needs to work with Python scientific and numerical libraries, namely, Python SciPy and Python NumPy, respectively. It’s basically a SciPy toolkit that features various machine learning algorithms. Scikit-learn has small standard datasets that we don’t need to download from any external web...
It was created to help simplify the process of implementing machine learning and statistical models in Python. The library enables practitioners to rapidly implement a vast range of supervised and unsupervised machine learning algorithms through a consistent interface. Sklearn was built on top of ...

sklearn.datasets里面集成了这个网站里的部分数据(刚接触Python的童鞋,需要一点点Python的知识,和Java类似,使用现成工具模块的时候,需要import一下,我们这个基于Python的机器学习工具包的全名是sklearn,这里介绍数据,所以下一个目录是datasets)。具体的Python代码: ...
