IBM Watson: is artificial cleverness the same as AI?
Let's start with the obvious: this is the opinion of one mere human. Someone who would fail miserably at the US quiz show Jeopardy: it's that 'sta
But an IBM supercomputer called Watson (which was indeed conceived on US soil) appears to be performing awfully well at the contest and as such is causing a lot of media attention, much of it centered around the whole field of artificial intelligence (AI) and IBM's involvement in this area.
As PC World reports, Watson overcame two Jeopardy all-time champs in a practice round recently. How does it do this? The silicon contestant has read countless encyclopedias and other tomes, contains natural language processing capabilities and can even determine how confident it is in its response. Couple this with industry-leading computational power and you have one efficient competitor.
IBM has a history in the development of pitting computers against humans on the cerebral battlefield. In the late 'nineties, Deep Blue defeated chess grandmaster Gary Kasparov (although Kasparov disputes that he was indeed beaten). However the team behind the Watson project are quick to point out that the level of computing required to deal with the high-level semantic reasoning they are up against is different to the logic-bound nature of chess. Chess is a game of limited moves on an 8x8 grid; Jeopardy a game of infinite words.
I can't help but think back to my Philosophy of the Mind classes where we studied the Turing test - that black box approach to measure AI proposed by Alan Turing in the 50s. Sometimes called the 'imitation game', the concept was that if someone could ask questions to a black box and not discern whether a computer or a person was inside, you could attribute intelligence to the machine on a par to that which us humans enjoy. This Stanford article does a good job of discussing the Turing Test and its objections in some detail.
One objection that stands out is that of origination: could a computer do more than just perform tasks (or deal with questions) set by humans? In the case of Watson, it was a team of people within IBM Research that came up with the idea to build a supercomputer to compete in Jeopardy. The motivations? Showcase technology. A fun work-related project. Team-building. The question is whether a computer could have had the 'wisdom' (foolhardiness) to come up with the idea of the project in the first place.
I'd suggest this level of decision-making is a quantum leap beyond the semantic analysis of IBM Watson.
Jonah Lehrer, in the prov
"Antonio Damascio, a neuroscientist who has done extensive work on the etiology of feeling, calls this process the body loop. In his view the mind stalks the flesh; from our muscles we steal our moods."
You can't separate our thought process from our bodily existence. This could be a problem for a computer lacking flesh and bones.
I don't just bring this up in the vein of being a contrarian or mean-spirited towards what is quite an astounding piece of computing. I think there is a message here that relates to the technology at the core of Watson: business analytics.
Decision-making within the enterprise happens at different levels and business analytics doesn't necessarily apply at all of those. For instance, business analytics is ideal at helping a marketer pinpoint prospects who might be interested in a particular offer. It's less good at determining whether that same marketer should run a conference program if they've never run one before. We're still not close to being able to automate that intuitive part of the decision-making process in business.
Last year I sat in a discussion around decision management and heard from a product marketing manager that a barrier to adoption of business analytics systems is the fear from decision-makers that this technology will take away their jobs (the very same people who normally sign the check on these kinds of purchases). This would suggest we in the field of business analytics need to do a better job of explaining that there are some decisions that can be automated and others that cannot. Business analytics consists of a set of tools that us humans can use to make smarter decisions, but like all tools, it has limits.
So whilst IBM Watson shows what computers can achieve in the human realm, it's worth bearing in mind (no pun intended) that computers pose little threat to the human realm. The Jeopardy contest that is coming up on February 14 is a battle of one computer against 2 humanoids. If Watson wins, we're not talking about the dawn of a new era where Jeopardy is played out by tin robots bearing the IBM insignia. We are talking about a triumph of a technology that has applications in healthcare and customer service and beyond - a technology that remains a tool in the hands of us mere humans.
