We Need To Unlock The Power Of Cause And Effect
In 2011, IBM’s Watson system beat the best human players in the game show, Jeopardy! Since then, machines have shown that they can outperform skilled professionals in everything from basic legal work to diagnosing breast cancer. It seems that machines just get smarter and smarter all the time.
Yet that is largely an illusion. While even a very young human child understands the basic concept of cause and effect, computers rely on correlations. In effect, while a computer can associate the sun rising with the day breaking, it doesn’t understand that one causes the other, which limits how helpful computers can be.
That’s beginning to change. A group of researchers, led by artificial intelligence pioneer Judea Pearl, are working to help computers understand cause and effect based on a new causal calculus. The effort is still in its nascent stages, but if they’re successful we could be entering a new era in which machines not only answer questions, but help us pose new ones.
Observation and Association
Most of what we know comes from inductive reasoning. We make some observations and associate those observations with specific outcomes. For example, if we see animals going to a drink at a watering hole every morning, we would expect to see them at the same watering hole in…
