AI is still not as clever as a six-year-old... for now
But Google’s AlphaGo proves brainier than Siri and Bing
Chinese researchers have found that Google's attempt at developing artificial intelligence, AlphaGo, is cleverer that Apple's Siri and Microsoft's Bing, but still not as clever as the average six-year-old.
The scientists have developed a way of measuring the intelligence of AI systems and devised a classification system to rank different AI systems. In tests, Google's AlphaGo system ranked highest.
The three researchers, Feng Liu, Yong Shi and Ying Liu, found that AlphaGo had an IQ of 47.28 in 2016, double that of Siri's 23.94, and higher than Microsoft's Bing (31.98), according to their research paper. However, the average six-year-old's IQ is around 55.5.
Despite its relatively low IQ, AlphaGo has managed to increase its IQ over the years. Back in 2014, the system managed an IQ score of 26.5.
Although artificial intelligence (AI) is currently one of the most interesting areas in scientific research, the researchers said "the potential threats posed by emerging AI systems remain a source of persistent controversy".
In order to address the issue of AI threat, their study "proposes a standard intelligence model that unifies AI and human characteristics in terms of four aspects of knowledge, i.e., input, output, mastery, and creation".
"Using this model, we observe three challenges, namely, expanding of the von Neumann architecture; testing and ranking the intelligence quotient of naturally and artificially intelligent systems, including humans, Google, Bing, Baidu, and Siri; and finally, the dividing of artificially intelligent systems into seven grades from robots to Google Brain. Based on this, we conclude that AlphaGo belongs to the third grade," it added.
Researchers said that the yearly trajectory of test results will allow for a comparison of selected artificial intelligence systems with the highest-IQ humans.
"As a result, future development of the relationship of artificial intelligence to human intelligence can be judged and growth curves for each intelligence that are mostly in line with the objectively recorded measures can be determined," they added.
