Product Description


"The book is the place to go if you're really interested in this version of the quest for creating Artificial Intelligence (AI)....lively" -Seattle Times

"Baker skillfully weaves the two threads of the story together, and the book contains many passages that make the reader not only assess what they think but how they think, and how they have absorbed and stored the knowledge they possess. It’s books like this that remind us there is still so much we don’t understand about our own brains, and that the journey of discovery has only just begun." -Culture Mob

"Baker's narrative is both charming and entertaining romp through the field of artificial intelligence - and a sobering glimpse of things to come." -STARRED, Publishers Weekly

Format: Hardcover
Meet Watson, a dedicated question/answer machine developed over several years through the concerted effort of a diligent team of researchers, scientists, mathematicians, and a host of other professionals.

Stephen Baker does an excellent job in Final Jeopardy tracing the history of Watson from his conception to the climactic match where he faces off with two of the greatest Jeopardy champions of all time.

The book is a story about Watson and the team that developed him. It does not go in-depth into the programming and algorithms at work in Watson's 'brain', but it certainly covers all of the ups and downs of his development in enough detail to satisfy the curiosity of most Jeopardy fans. It is highly readable, engaging, and occasionally funny; I would heartily recommend Final Jeopardy to anyone who loves the game and is fascinated by the engineering feat that has become known as Watson.

HASH(0xa13c8f48) out of 5 stars Rare to have this much fun reading a book AND to learn so much! Feb. 9 2011
By Len Edgerly - Published on
Format: Kindle Edition Verified Purchase
Stephen Baker's account of the creation and teaching of IBM's Watson computer, preparing it for the climactic Jeopardy contest with the two top living human Jeopardy champions, is a delight to read AND a highly informative overview of artificial intelligence and the role computers will play in our lives from here on out. You get to know and appreciate the complex, talented characters of the story at IBM and in Hollywood. The growing sense of drama makes the book un-put-downable. Will IBM's engineers prepare Watson to figure out the pun-filled, playful and quirky categories of Jeopardy? Will the Hollywood execs agree to fair terms of engagement? And, most intriguingly, who will win the final showdown?

I love what Baker's publisher has done with the Kindle version of this book - making the first 11 chapters available well before the showdown Jeopardy match airs on Feb. 14-15-16. After the actual match took place, in great secrecy, Baker wrote the final chapter of his book, which will arrive as a Kindle download the day after the final match, when the hardcover will also be available, with all the chapters. This is a fantastic use of e-book technology, so bravo to Houghton Mifflin for such a clever and Kindle-friendly innovation.

HASH(0xa1454594) out of 5 stars Fantastic Book!!! Feb. 12 2011
By Tim - Published on
Format: Kindle Edition Verified Purchase
Heard the author's interview with Len Edgerly on the Kindle Chronicles on February 5, 2011 (TKC 133). Had to purchase and read the book after listening. I finished the book last night and am looking forward now to the match this next week. I learned a lot about what IBM had to do to get ready for the match and the problems that needed to be overcome. I would recommend this book to anyone who would like to know about AI and especially about the people who are working on this project. I am thankful to the publisher for putting the book out in e-book form prior to the match. I really look forward to reading the last chapter this next week!!!

HASH(0xa195719c) out of 5 stars As others said, a little too much story July 23 2011
By 12milluz - Published on
Format: Kindle Edition Verified Purchase
I got this book because I am intrigued with Jeopardy (my best friend was a participant in the show before) and I love computers. When I first heard about Watson, I was very interested in what they were doing. I thought this book would be the perfect source to learn more.

It is written fantastically and is fun to read, but it does not go into the technology too much, which is what I was looking for. Still, I enjoyed reading and learning. I had no idea how many problems there were with both the technology and the business aspect of the program. The book goes into the areas of logic and AI as well, and gives some history of IBM and its chess-playing computer of the past.

Anyone who's looking for a nice, easy read should take a look at this book. Techies: It probably won't fill your needs in terms of describing the technology, but it's still fun to read. There isn't any other source as complete as this on Watson. Take a look!

HASH(0xa132dd50) out of 5 stars An Uplifting Tale By a Gifted Writer Feb. 19 2011
By Don Tennant - Published on
Format: Hardcover
I had the opportunity to read an advance copy of Final Jeopardy that was released prior to the match, without the final chapter about the outcome. When the match aired, I felt like I was seeing a bunch of old friends who had managed to get themselves on TV. Watson was only one of my new best buds. I also got a kick out of seeing the cast of characters at IBM whom I had come to know through Steve Baker's book. I found myself unapologetically rooting for them, and being exhilarated by their victory, having gotten a behind-the-scenes sense of just how much of themselves the IBMers had given to make the miracle of Watson happen.

I attribute all of that to Baker's remarkable story-telling and character-developing abilities, which enabled him to craft an engaging narrative about a labyrinthine project and esoteric subject matter that might easily have confounded the non-engineers among us. The most richly developed character was Watson him/her/itself, not through any cutesy, artificial anthropomorphism, but though a mosaic of triumphs and setbacks that seemed to transcend the IBM team that created it.

Baker managed to put it all in a context that enables us to grasp the potential of Watson and the computer systems that will follow it, so that we can appreciate that what might on the surface have appeared to be little more than self-indulgent technological gimmickry was actually a quest to improve people's lives in ways that could only be vaguely imagined in the very recent past. Watson, in the end, is a proof of concept that will ultimately benefit us all. Its creation is an uplifting tale, and one that warranted a gifted writer to tell it. It's fortunate that Baker rose to that occasion.

HASH(0xa17ed5f4) out of 5 stars A Turning Point for Mankind - Feb. 28 2011
By Loyd Eskildson - Published on
Format: Hardcover
IBM's Watson computer soundly defeated the two highest-rated Jeopardy former champions earlier this year, signifying the dawn of a new age of computer-assisted decision-making. It was also a massive marketing coup for IBM and Jeopardy. Stephen Baker's "Final Jeopardy" reports on how Watson came to this latest achievement, along with hints of what comes next.

Originally computers were limited to rapidly processing data according to predefined rules, first for individual questions (eg. military applications), then larger and larger batches of commercial data, and eventually immediate 'real-time' response. Next came IBM's 'Deep Blue' defeat of the reigning 1997 chess champion, Garry Kasperov, demonstrating its ability to analyze millions of scenarios/second to select the moves most likely to win - an impressive new mathematical achievement. Winning Jeopardy, however, required the computer to analyze English natural-language words and phrases, despite confusing puns, idioms, allusions, double-meanings, trick questions, and the importance of syntax, and then select the most likely correct answer from a giant electronic database containing Project Gutenberg (33,000 highly rated e-books), dictionaries, taxonomies, thesauri, encyclopedias, news articles, book abstracts, famous works of music and art, etc., without an Internet connection - all within a maximum of five seconds. Watson also had to determine optimal betting strategies, taking into account current point rankings, as well as the potential earnings and betting opportunities remaining.

David Ferrucci, an artificial intelligence (AI) expert within IBM was selected to lead its Jeopardy effort. He first declined the request, believing it impossible to build a system within the requested three years that could beat the best-known Jeopardy champions. Later, in response to a second request, he decided that it could be done and led a team of 25 scientists that accomplished the task within four years.

Some thought the task would simply require a Google-like program; Google, however, does not actually answer questions - it simply provides information for humans to do so. On the other hand, simple questions (eg. What is the highest mountain?) represent about 30% of Jeopardy queries, per Baker. It was the remaining 70% or so that mostly concerned Ferrucci and his colleagues, as well as Ken Jennings' fast responses and historical correct answer rate of about 92%. The second bit of 'good news' for the team was their realization that Watson didn't need to know the content of books, artwork, plays, music, sitcoms with the level of detail required to eg. compare and contrast their contents - just key points and protagonists.

Initial Watson responses, says Baker, took 90 minutes to two hours - obviously inadequate for Jeopardy. Ferrucci and his IBM team solved that problem by reconfiguring Watson to consist of 90 IBM server computers, each with four 8-core processors, and using 15 TBs (terabytes) overall of rapid access (solid state) memory (RAM), and then dividing its tasks into thousands of stand-alone jobs distributed among 80 teraflops of processing power for parallel processing. (1 TB of memory can hold 220 million text pages; a teraflop = 1 trillion operations/second.)

Unfortunately, Baker's book does not provide details on how these Linux-managed algorithms and processors are able to work together and in sequence. Neither do we learn much about how AI takes eg. any subject and determines what types of words are most and least associated with it, or Watson's use of some 100+ algorithms to analyze a question in different ways, the results of which are then ranked by another set of algorithms (eg. "Was the contender alive that year?"). (New York Times, 6/20/2010).

"Final Jeopardy" also provides few details about the hardware, requiring two 20-ton A/C units to cool, and operating at 3.3 gigahertz (gigahertz = billion cycles/second).

Much of the Watson project's time was taken up with devising ways to prevent errors uncovered in its constant preparation competitions with lesser-known Jeopardy champions. The group also was worried about Watson making IBM look bad by losing badly or spitting out inappropriate four-letter words. Then there were battles with Sony (Jeopardy's owner) over requiring Watson to use a mechanical finger to 'buzz in' (IBM agreed; a number of contestants proved faster by anticipating host Trebek's speaking), allowing Watson to 'see' the correct response after every question (allow Watson to improve its understanding about what the category was looking for - Sony agreed), and insuring that the category/question selection was done in a new, incontestably fair manner (Sony agreed - IBM did not want Watson's achievements to be challenged on the basis of some bias. Visual clues, however, were excluded, because of Watson's inability to process such.)

Baker also tells us that the best Jeopardy champions had their own preparation and competition strategies. Some contestants used 'Anki,' a site that provides electronic flashcards for hundreds of study fields, and J! Archive, a site that helped both IBM and various contests determine the likelihood of various categories being used. The best, including Watson, deliberately searched for Daily Double questions (more likely found in the higher-dollar questions), especially in Double Jeopardy, as a means of both keeping those potential game-changers out of opponents' hands and possibly boosting one's own standing, if needed. Google Scholar was also used by some contestants (and probably IBM as well) to refine Final Jeopardy betting and overall answer generation.

Watson's ultimate triumph against Ken Jennings and Brad Jennings in "Final Jeopardy" is a bit anticlimactic, though not without a few scary blunders by Watson. The biggest - identifying Toronto as an American city. Strangely, despite Watson's triumph, IBM was simultaneously struggling to avoid cancellation of a contract with the California Dept. of Education to answer much simpler questions such as "Do 8th-grade students enrolled in Algebra I perform better, on average, if their teacher has a credential in math?" (Huffington Post, 2/22/2011).

The first computer I worked on (1967) had 16 K (K = thousand units) of memory and a 10 K processor speed (thousand operations/second). Watson's memory is over 1 billion times greater, and its processor speed 8 billion times faster. China's 'Big Red,' the world's fastest computer, is over 30X faster than Watson; Big Blue, however, is expected to counter with 'Sequoia' in 2011 - about ten times faster yet. Thus, this year will bring processing speeds about 2.5 trillion times as fast as the mid-1960s, and 300 times as fast as Watson. More efficient algorithms will undoubtedly accompany the increased power.

Baker sees Watson as already able to easily digest and synthesize the tens of thousands of medical research papers published every year to help physicians make diagnoses and treatment plans. (A general lack of medical research meta-analyses is a major problem in medicine that future Watson's could likely provide.) IBM is now moving in this direction, starting by incorporating improved speech recognition software from Nuance Communications, and working with medical experts. Call centers, legal work, offer other potential, though less glamorous, applications.

Bottom-Line: Stephen Baker's "Final Jeopardy" gives us a glimpse into the future, where bytes better brains, just as previously machines and robots beat brawn. Watson's victory brings us to the point where the future becomes unpredictable, per Ray Kurzweil and others, due to our inability to imagine the capabilities of artificial intelligence increasing at exponential speeds, simultaneously pursuing and combining revolutionary discoveries in biology, nanotechnology, medicine, etc. ("The Singularity is Near") Readers will be left wondering what humans will do in the future, what incredible advancements in science and medicine are already underway, whether society becomes more controlled using this power (Bill Joy, co-founder of Sun Microsystems), etc.?
