Re: Is Watson the most advanced super computer in existence?

I did some addtional reserach and Watson isn't the most advanced computer but he's up there. I had never heard of this system but Univeristy of Illinois tested 'Concept Net 4' developed by MIT. They found it has the intelliegence of a 4 year old.


WASHINGTON: One of the world's best artificial intelligence computers is only as smart as a four year old human child, a new study suggests. Researchers at the University of Illinois at Chicago IQ-tested one of the best available artificial intelligence systems to see how intelligent it really is.
It turned out that the computer is about as smart as the average four-year-old, researchers said.
The UIC team put ConceptNet 4, an artificial intelligence system developed at Massachusetts Institute of Technology (MIT), through the verbal portions of the Weschsler Preschool and Primary Scale of Intelligence Test, a standard IQ assessment for young children.
They found ConceptNet 4 has the average IQ of a young child. But unlike most children, the machine's scores were very uneven across different portions of the test.
"If a child had scores that varied this much, it might be a symptom that something was wrong," said Robert Sloan, professor and head of computer science at UIC, and lead author on the study.
Sloan said ConceptNet 4 did very well on a test of vocabulary and on a test of its ability to recognise similarities.
"But ConceptNet 4 did dramatically worse than average on comprehension - the 'why' questions," he said.
One of the hardest problems in building an artificial intelligence, Sloan said, is devising a computer programme that can make sound and prudent judgement based on a simple perception of the situation or facts-the dictionary definition of commonsense.
Commonsense has eluded artificial intelligence engineers because it requires both a very large collection of facts and what Sloan calls implicit facts-things so obvious that we don't know we know them. A computer may know the temperature at which water freezes, but we know that ice is cold.
"All of us know a huge number of things. As babies, we crawled around and yanked on things and learned that things fall. We yanked on other things and learned that dogs and cats don't appreciate having their tails pulled," said Sloan.
"We are still very far from programmes with commonsense - artificial intelligence that can answer comprehension questions with the skill of a child of eight," said Sloan.
Google is also apparently using a Quantum Computer for AI like modeling:

T
he nonprofit Universities Space Research Association just splurged on a new toy: A $10 million D-Wave Two quantum computer. The machine is the most advanced commercially available quantum computer in the world.
USRA installed the device, which should be online by the end of September, at the new Quantum Artificial Intelligence Lab at the Ames Research Center in Silicon Valley, where researchers from USRA, NASA, and Google will put it use.
What is a quantum computer? Think of it this way: Regular computers process information using bits, which can innately have only one of two values (zero or one, plus or minus, yes or no, etc). Quantum computers use qubits, which can simultaneously represent more than one value. In that sense, "quantum computing could herald a new era of number-crunching," said Robert McMillan at Wired, by breaking out of the "binary" system of computing. USA Today explains:
A quantum computer takes advantage of a principle in physics that on the atomic scale particles can be in many places at once or have multiple properties such as magnetism or an electrical charge simultaneously. They would store data in these multiple positions at once, unlike conventional computers, which only store one value or data point in their circuits at a time. [USA Today]
That means Qubits can multitask, which results in outstanding power. "A quantum computer with 300 qubits could run more calculations in an instant than there are atoms in the universe," says Technology Review.
