I would like to thank Baran Toppare, my mentor for introducing and guiding me through the wonderfully exciting world of data science (and recommendation systems). I am also grateful to Parul Gupta and Indrajit Rajtilak, my former colleagues at Springboard. Without their support, I would not have pursued the Data Science Career Track and therefore, this book would never have been a reality. 
Finally, I'd like to thank my family and all my friends in college for being a constant source of motivation, inspiration and support that enabled me to complete this book.
