Python Data Science Essentials

Overview of this book

The book starts by introducing you to setting up your essential data science toolbox. Then it will guide you across all the data munging and preprocessing phases. This will be done in a manner that explains all the core data science activities related to loading data, transforming and fixing it for analysis, as well as exploring and processing it. Finally, it will complete the overview by presenting you with the main machine learning algorithms, the graph analysis technicalities, and all the visualization instruments that can make your life easier in presenting your results. In this walkthrough, structured as a data science project, you will always be accompanied by clear code and simplified examples to help you understand the underlying mechanics and real-world datasets.

Summary


This chapter provides an overview of essential data science by providing examples of both basic and advanced graphical representations of data, machine learning processes, and results. We explored the pylab module from matplotlib, which is the easiest and fastest access to the graphical capabilities of the package, used pandas for EDA, and tested the graphical utilities provided by Scikit-learn. All examples were like building blocks, and they are all easily customizable in order to provide you with a fast template for visualization.

In conclusion, this book covered all the key points of a data science project, presenting you with all the essential tools to operate your own projects using Python. As a learning tool, the book accompanied you through all the phases of data science, from data loading to machine learning and visualization, illustrating best practices and ways to avoid common pitfalls. As a reference, the book touched upon a variety of commands and packages, providing...
