AlphaGo pushed human Go gamers to change into extra inventive

Earlier this 12 months, an beginner Go participant one of many recreation’s top-ranked AI techniques. They did so utilizing a technique developed with the assistance of a program researchers designed to probe techniques like KataGo for weaknesses. It seems that victory is only one a part of a broader Go renaissance that’s seeing human gamers change into extra inventive since

In a latest research revealed within the journal , researchers from the Metropolis College of Hong Kong and Yale discovered that human Go gamers have change into much less predictable lately. Because the , the researchers got here to that conclusion by analyzing a dataset of greater than 5.8 million Go strikes made throughout skilled play between 1950 and 2021. With the assistance of a “superhuman” Go AI, a program that may play the sport and grade the standard of any single transfer, they created a statistic referred to as a “choice high quality index,” or DQI for brief.

After assigning each transfer of their dataset a DQI rating, the group discovered that earlier than 2016, the standard {of professional} play improved comparatively little from 12 months to 12 months. At most, the group noticed a constructive median annual DQI change of 0.2. In some years, the general high quality of play even dropped. Nevertheless, because the rise of superhuman AIs in 2018, median DQI values have modified at a fee above 0.7. Over that very same interval, skilled gamers have employed extra novel methods. In 2018, 88 p.c of video games, up from 63 p.c in 2015, noticed gamers arrange a mixture of performs that hadn’t been noticed earlier than. 

“Our findings recommend that the event of superhuman AI applications might have prompted human gamers to interrupt away from conventional methods and induced them to discover novel strikes, which in flip might have improved their decision-making,” the group writes.

That’s an fascinating change, however not precisely an unintuitive one if you consider it. As professor Stuart Russel on the College of California, Berkeley informed the New Scientist, “it’s not stunning that gamers who practice towards machines will are likely to make extra strikes that machines approve of.”
