Introduction to Scikit‐learn

In Chapters 2–4, you learned how to use Python together with libraries such as NumPy and Pandas to perform number crunching, data visualization, and analysis. For machine learning, you can also use these libraries to build your own learning models. However, doing so would require you to have a strong appreciation of the mathematical foundation for the various machine learning algorithms—not a trivial matter.

Instead of implementing the various machine learning algorithms manually by hand, fortunately, someone else has already done the hard work for you. Introducing Scikit‐learn, a Python library that implements the various types of machine learning algorithms, such as classification, regression, clustering, decision tree, and more. Using Scikit‐learn, implementing machine learning is now simply a matter of calling a function with the appropriate data so that you can fit and train the model.

In this chapter, first you will...
