Acknowledgments
I am very grateful to my parents, who have always encouraged me to pursue
knowledge. I also want to thank my wife, Saroar; son, Shadman; brother, Mamtaz;
sister, Josna; and friends who have endured my long monologs about the subjects
in this book and always have encouraged and listened to me. Writing this book
was made easier by the amazing efforts of the open source community and the
great documentation of many projects out there related to TensorFlow and Python.
Further, I would like to thank the acquisition, content development, and technical
editors of Packt Publishing Ltd. (and, of course, others who were involved in this
book title) for their sincere cooperation and coordination. Additionally, without the
work of numerous researchers and deep learning practitioners who shared their
expertise in publications, lectures, and source code, this book might not have existed
at all! Finally, I appreciate the efforts of the TensorFlow community and all those
who have contributed to APIs, whose work ultimately brought machine learning
to the masses.
