Data pre-processing for machine learning in Python - eBook

In this book, the author shows the practical use of Python programming language to perform pre-processing tasks in machine learning projects.

What is pre-processing?

Pre-processing is the set of transformations to be applied to a dataset before it can be used to train a machine learning model. It's a very important phase of a data science pipeline because a wrong pre-processing will give a very poor performance of the model, while a good pre-processing is able to make the model learn properly.

The pre-processing transformations shown in this book are:

• Data cleaning
• Encoding of the categorical variables (one-hot encoding and ordinal encoding)
• Principal Component Analysis
• Scaling (normalization, standardization, robust scaling)
• Binarizing
• Binning
• Power transformations
• Filter-based feature selection
• Oversampling using SMOTE

All the transformations are described in theory and in practice using Python programming language and its powerful scikit-learn library.

What will I get?

By buying this book you'll get it in ePub and PDF formats. Plus, you'll get the sample dataset used in the book and 18 Python notebooks.

Is there a paperback format available?

Sure! You can order it on Amazon.
