Mastering Data Mining with Python - Find patterns hidden in your data

By: Megan Squire

Overview of this book

Data mining is an integral part of the data science pipeline. It is the foundation of any successful data-driven strategy – without it, you'll never be able to uncover truly transformative insights. Since data is vital to just about every modern organization, it is worth taking the next step to unlock even greater value and more meaningful understanding. If you already know the fundamentals of data mining with Python, you are now ready to experiment with more interesting, advanced data analytics techniques using Python's easy-to-use interface and extensive range of libraries. In this book, you'll go deeper into many often overlooked areas of data mining, including association rule mining, entity matching, network mining, sentiment analysis, named entity recognition, text summarization, topic modeling, and anomaly detection. For each data mining technique, we'll review the state-of-the-art and current best practices before comparing a wide variety of strategies for solving each problem. We will then implement example solutions using real-world data from the domain of software engineering, and we will spend time learning how to understand and interpret the results we get. By the end of this book, you will have solid experience implementing some of the most interesting and relevant data mining techniques available today, and you will have achieved a greater fluency in the important field of Python data analytics.

Summary


In this chapter, we learned how to generate frequent itemsets from a dataset using the Apriori algorithm. We then proposed association rules from these itemsets by describing their support and confidence. We used one additional check, an added value measure, to ensure that the proposed rules were interesting. We implemented all these concepts using a freely available dataset of Freecode open source projects and their tags. We calculated support for single tags, then generated doubletons and tripletons that met a minimum support threshold. For rules with one item on the right-hand side, we calculated confidence and added value for each. Finally, we looked closely at the rules that were generated and tried to figure out which ones were interesting, using the metrics we had calculated.

In the next chapter, we will continue our quest to make connections between items in a data set. However, unlike in this chapter where we were trying to find groups of two or three items that are already...
