Foreward

I have been teaching data science as a part-time faculty and have taught hundreds of students. Many of my students have successfully transitioned to a data science career. I also have a set of open-source contributions as python libraries. I often get requests from my previous students when they start working on their first real machine learning project. I found the root cause of many challenges faced by my students who recently transitioned into data science and machine learning. I have tried to address these issues in my book and would like to dedicate this book to all my students for all the love and respect I have received.

There are many methods for feature engineering, feature selection and signal processing which were not available previously in python. I have coded and open-sourced these methods as python libraries over the years. Often, I get approached by researchers who use my python libraries, for understanding how to use certain algorithms and best practices for these algorithms. I have tried to explain these with the aid of underlying theory, and visualizations in this book.
