Learning Data Mining with Python - Second Edition

By: Robert Layton

Overview of this book

This book teaches you to design and develop data mining applications using a variety of datasets, starting with basic classification and affinity analysis. This book covers a large number of libraries available in Python, including the Jupyter Notebook, pandas, scikit-learn, and NLTK. You will gain hands on experience with complex data types including text, images, and graphs. You will also discover object detection using Deep Neural Networks, which is one of the big, difficult areas of machine learning right now. With restructured examples and code samples updated for the latest edition of Python, each chapter of this book introduces you to new algorithms and techniques. By the end of the book, you will have great insights into using Python for data mining and understanding of the algorithms as well as implementations.

Getting Started with Data Mining

In this chapter following are a few avenues that reader can explore:

Scikit-learn tutorials

URL: http://scikit-learn.org/stable/tutorial/index.html

Included in the scikit-learn documentation is a series of tutorials on data mining. The tutorials range from basic introductions to toy datasets, all the way through to comprehensive tutorials on techniques used in recent research. The tutorials here will take quite a while to get through—they are very comprehensive—but are well worth the effort to learn.

There are also a large number of algorithms that have been implemented for compatability with scikit-learn. These algorithms are not always included in scikit-learn itself for a number of reasons, but a list of many of these is maintained at https://github.com/scikit-learn/scikit-learn/wiki/Third-party-projects-and-code-snippets.

Extending the Jupyter Notebook

The Jupyter Notebook is a powerful tool...
