Terisa Roberts: To my husband, best friend, and partner, Johan, and our three children, Gary, Cara, and Isabella. Thank you for making me laugh. Stay curious and always keep dreaming.

Stephen J. Tonna: To my darling wife, Nini, and newborn son, Sebastian James, who have both heard the “tap” of laptop keys into the early mornings … my apologies for all the noise, but the amazing outcome is that little Sebastian is now an avid fan of both typing on laptop to help Papa and learning principles of machine learning algorithms!
