Python Data Science Essentials - Second Edition

By: Luca Massaron, Alberto Boschetti

Overview of this book

Fully expanded and upgraded, the second edition of Python Data Science Essentials takes you through all you need to know to suceed in data science using Python. Get modern insight into the core of Python data, including the latest versions of Jupyter notebooks, NumPy, pandas and scikit-learn. Look beyond the fundamentals with beautiful data visualizations with Seaborn and ggplot, web development with Bottle, and even the new frontiers of deep learning with Theano and TensorFlow. Dive into building your essential Python 3.5 data science toolbox, using a single-source approach that will allow to to work with Python 2.7 as well. Get to grips fast with data munging and preprocessing, and all the techniques you need to load, analyse, and process your data. Finally, get a complete overview of principal machine learning algorithms, graph analysis techniques, and all the visualization and deployment instruments that make it easier to present your results to an audience of both data science experts and business users.

Preface

Summary


In this chapter, we extracted significant meanings from data by applying a number of advanced data operations-from EDA and feature creation to dimensionality reduction and outlier detection.

More importantly, we started developing, with the help of many examples, our data pipeline. This was achieved by encapsulating into a train/cross-validation/test setting our hypothesis that was expressed in terms of various activities-from data selection and transformation to the choice of learning algorithm and its best hyperparameters.

In the next chapter, we will delve into the principal machine learning algorithms offered by the Scikit-learn package, such as-among others-linear models, support vectors machines, ensembles of trees, and unsupervised techniques for clustering.
