AIQ by Nick Polson and James Scott


AIQ by Nick Polson and James Scott describes “How People and Machines Are Smarter Together” by providing a useful overview of Artificial Intelligence and associated concepts. In fact, the authors acknowledge that AI technologies bring “immense benefits” along with some “dangers to watch out for,” promising that the book “will show you what you need to understand if you want to play an informed role” in the discussion of future policy on AI.

And, indeed, what makes this book AIQ so compelling is the ease with which key ideas are explained. There are only 7 chapters and each is devoted to a person who made a significant contribution to AI.  For example, “The Refugee” focuses on a Hungarian-American named Abraham Wald who invented sequential sampling and worked in the 1930s and 40s with other mathematical geniuses like Milton Friedman and George Stigler. Wald helped save the lives of Allied fighter pilots and their crews during WWII by devising personalized survivability recommendations for the aircraft. Authors Polson and Scott point out the similarities to present day personalized recommendations from services like Netflix.  Significantly, they note that “the key algorithms of the future are about suggestions, not search.”   

Throughout other chapters, Polson and Scott provide a varied set of examples and point to the presence of four trends driving the current explosion in demand and capacity for using AI to solve problems.  These trends are faster chips, massive data sets (some of the figures will astound you!), cloud computing (meaning lower overhead costs) and good ideas! Polson and Scott further note that pretty much every AI system (including their examples of electric cars, cucumber sorters and credit card fraud monitors) follow the same ‘pipeline of algorithms’ template where “the pipeline takes in data from some specific domain, performs a chain of calculations, and outputs a prediction or a decision.” I have already suggested this book to students and look forward to seeing how excited they are as they grasp simple explanations and better understand the history for seemingly sophisticated tasks. Fascinating!
