PORTLAND, Ore.—The stunning victory of IBM's Watson cluster computer over human champions Ken Jennings and Brad Rutter on the quiz show Jeopardy proved that artificial intelligence algorithms make the system capable of being an expert's advisor, but not in becoming an expert itself.
IBM is currently adapting Watson DeepQA architecture to commercial applications, where it will act as an advisor to human experts, thus defusing criticisms that it is not an expert itself (after Watson asserted during the Jeopardy game that Toronto was a U.S. city). By filtering Watson's advise through the expertise of a human—to eliminate such obvious mistakes—IBM hopes to apply Watson to a variety of fields, including healthcare, financial services, government-mandate management and retailing.
On Wednesday (Feb. 16), Watson wrapped up the victory in a three-day match up, finishing with $77,147, well ahead of Jennings ($24,000) and Rutter ($21,600). For winning the Jeopardy IBM Challenge, Watson pulled down a cool $1 million. IBM said it planned to donate the money to two charities-- World Vision and Worldwide Community Grid.
For medical applications, IBM plans for Watson-like systems that act as an expert consultant for doctors. By comparing a patient's symptoms to those of millions of other patients worldwide, along with the treatments that cured them and all the latest information from medical journals, Watson will supply a ranked list of possible diagnoses. Of course, if the computer makes obvious mistakes on such a list, the doctor will delete these before communicating its diagnostic advice to patients.
On Thursday, IBM and Nuance Communications Inc. announced a research agreement to explore, develop and commercialize the Watson computing system's advanced analytics capabilities in the healthcare industry.

In the financial services area, Watson will provide real-time analytics to financial institution experts, allowing them to what-if analysis on market data, current events, the opinion of analysts and a thousand other unstructured information sources that are difficult to combine using in to conventional algorithms. Here the human experts will interpret recommendations, as with medical applications, thus shielding users from a computer's mistakes.
Likewise, for clarifying the dizzying array of laws and regulations that take human experts weeks or months to sort out, Watson will be able to cut that analysis time down to hours or even minutes, with any mistakes corrected by the human experts supervising its work, according to IBM.
In retail settings, IBM will use Watson to consider past buying patterns, inventory, order management, supply chain and other customer relationship management issues that target individual buyers. Here, mistaken recommendations will not count against Watson, since people are used to "irrational" buying patterns due to issues such as brand loyalty, which transcends rational analysis, according to principal scientist Aditya Vailaya at Retrevo Inc. (Sunnyvale, Calif.).
"I expected Watson to win," said Vailaya. "And watching how Watson won validated my feelings that these problems are solvable, but not without a few caveats."
Retrevo runs multiple parallel algorithms similar to the learning methods that Watson used to answer Jeopardy clues, but Retrevo's domain is consumer products. Using a cluster of 50 Intel processors, Retrevo scans the product specifications, reviews, user reports, blog entries and other web-based information sources to answer user's questions about what products offer the best overall value. Watson will also face the same challenges that Retrevo when it is applied to retailing, according to Vailaya.
"The challenge for Watson was that it took them four or more years to build the system to be as good as it is," said Vailaya. "Most of the algorithms Watson uses are available for broad general cases, but they have to be trained for specific applications."
The issue is not computational horsepower, according to Vailaya, but algorithm refinement—and that takes time to develop. Retrevo, for instance, constantly evaluates over 50 million data sources regarding the 20,000 products it provides advice about on its website. But it has taken six years since the company was founded in 2005 to "be as good as it is"—a learning curve that Watson's spinoffs will have to go through for each application to which IBM's DeepQA architecture is applied, according to Vailaya.
Watson had to wager after the category was listed but BEFORE the clue was given, i.e., during the commercial break. It's wager could only be based on the category and the relative positions of the other contestants, not the question(answer) itself.
Since there were fixed payouts for each position it could have bet 0 and still won.

I think IBM has got some product the stand distinctively along with Microsoft and Apple with this intutive technology demonstration. I hope this will be the become the technology in demand in the comming future.
People better get used to looking like idiots; they will lose more and more to computers. We "lost" to computers when we started pecking away on electronic qwerty keyboards substituting for most conversations. We also "lost" the art of storytelling when books made storytelling a science. But we gained an awful lot of new avenues of expression, as witnessed by conversations on websites. Now we need to filter most of them. Oh but wait, aren't we doing that at cocktail parties already?
I was sitting next to an IBMer in an airline club yesterday. Overheard him tell a colleague that Watson is now going on tour, but didn't expect many challenges as people wouldn't want to look like idiots when they lost!

Wow this is simply amazing. I am sure this will help us solve many real-time complex problems. Kudos to IBM for contributing this machine to the mankind.
The Toronto answer to U.S. cities question that stomped Watson stomped me too. Its turns out there are seven states with cities names Toronto, but Watson was "smart" enough to "understand" that the answer had a low-probability of being correct, thus was programmed to wager pocket change to stay ahead in the game. That in itself is monumental progress in human-like decision-making. Watson will do great at horse racing tracks, too.
