First and foremost, I would like to thank my loving parents and younger brother Vaibhav for standing beside me throughout my career as well as while writing this book. Without their support it would have been totally impossible to achieve this knowledge sharing. As I started writing this book, I was continuously motivated by my father (Prahlad Prajapati) and regularly followed up by my mother (Dharmistha Prajapati). Also, thanks to my friends for encouraging me to initiate writing for big technologies such as Hadoop and R.

During this writing period I went through some critical phases of my life, which were challenging for me at all times. I am grateful to Ravi Pathak, CEO and founder at Tatvic, who introduced me to this vast field of Machine learning and Big Data and helped me realize my potential. And yes, I can't forget James, Wendell, and Mandar from Packt Publishing for their valuable support, motivation, and guidance to achieve these heights. Special thanks to them for filling up the communication gap on the technical and graphical sections of this book.

Thanks to Big Data and Machine learning. Finally a big thanks to God, you have given me the power to believe in myself and pursue my dreams. I could never have done this without the faith I have in you, the Almighty.

Let us go forward together into the future of Big Data analytics.
