A hundred years from now, historians might wonder when humanity fast-tracked its transition into the digital age. While it may be difficult to pin down an exact moment, the week of October 5 to 9, 2015, might be one of the places to look for.
During this short period of time, Google-owned artificial intelligence firm DeepMind won the upper hand in the highly complex Chinese board game of Go against a human player.
The contest was by no means a geek event for game freaks. It was proof-of-concept that artificial intelligence could, at least partially, live up to its ultimate goal of reaching human-like qualities.
Experts had considered the ancient game, which was already played during the time of Chinese philosopher Confucius more than 2500 years ago, too difficult for a computer to handle.
The number of possible moves in Go is bigger than the number of atoms in the observable universe. Calculating such an enormous number would be beyond even the most powerful supercomputers.
To overcome the gargantuan computing challenge, researchers at DeepMind devised an ingenious trick: Rather than compute every possible move with their new super-fast microprocessors, engineers developed a process using so-called deep neural networks with millions of connections, which were arranged much like neurons in the human brain.
The layered neural systems helped reduce computing needs as they narrowed down the search space, calculating only those moves deemed most likely to win the game. Through this staggered approach, known as deep learning, the algorithm tackled the problem in a “much more human-like” manner, as DeepMind CEO Demis Hassabis described the technique.
The artificial intelligence community was aflame after Google published the results in January 2016. A few weeks later, after DeepMind’s system beat South Korean Go champion Lee So-dol, an avalanche of media reports around the world touted the superiority of artificial intelligence systems over human ingenuity.
AI, and with it the promises of data and digital, had re-awakened.
