Google DeepMind's AlphaGo program on Tuesday beat a Chinese world champion in the first of three Go games held this week, in what is being hailed as a victory for artificial intelligence (AI).

The human player, Ke Jie, notes the program has improved rapidly after its 2016 defeat of a South Korean Go player. "AlphaGo is like a different player this year compared to last year," Ke says.

DeepMind co-founder Demis Hassabis says AlphaGo uses methods in which it learns experientially from playing a large number of games. For the new contest, Hassabis notes the program adopted a strategy that enables it to learn more by playing games against itself.

"Last year it was still quite humanlike when it played," Ke says. "But this year, it became like a god of Go."

Researchers say similar AI methods could be used to perform many tasks, such as improving basic scientific research.
