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.

What is a network?


Networks are all around us. We use the word network to refer to many different types of connected things: multiple computers hooked together, a system of cities connected by small roads and large highways, a group of people who all work in the same industry, a series of television stations that broadcast common programming. In common usage, the word network can refer to almost any set of interconnected entities.

From a data mining perspective, however, our use of the word network is more precise. We use the word network to refer to a system that can be represented by a graph made up of nodes and links. In our specialized vocabulary, nodes are the things being connected, and the links are the relationships between the nodes. The collection of all the nodes and links is called a graph. Note that we are using the word graph in its mathematical sense, not in the sense of a visualization, like a bar graph or a line graph. In graph theory vocabulary, nodes are also called vertices...
