Is playing 'Space Invaders' a milestone in artificial intelligence?







Excerpt from latimes.com


Computers have beaten humans at chess and “Jeopardy!,” and now they

can master old Atari games such as “Space Invaders” or “Breakout”

without knowing anything about their rules or strategies.

Atari 2600 games from the 1980s may seem a bit “Back to the Future,” but

researchers with Google’s DeepMind project say they have taken a small

but crucial step toward a general learning machine that can mimic the

way human brains learn from new experience.



Unlike the Watson and Deep Blue computers that beat “Jeopardy!” and

chess champions with intensive programming specific to those games, the

Deep-Q Network built its winning strategies from keystrokes up, through

trial and error and constant reprocessing of feedback to find winning

strategies.

“The ultimate goal is to build smart, general-purpose

[learning] machines. We’re many decades off from doing that,” said

artificial intelligence researcher Demis Hassabis, coauthor of the study

published online Wednesday in the journal Nature. “But I do think this is the first significant rung of the ladder that we’re on.” 

The Deep-Q Network computer, developed by the London-based Google DeepMind, played 49 old-school Atari games, scoring “at or better than human level,” on 29 of them, according to the study.
