The artificial intelligence (AI) of the US company OpenAI has learned to play the computer game Minecraft. The neural network was able to do this, which no AI was able to do before.
Artificial intelligence (AI) systems are evolving at breakneck speed. While computers still had problems solving complex tasks a few years ago, AI is now sometimes even better than humans. The most recent examples are chess tournaments and the board game Go, which computers have already won against humans.
AI dominates Minecraft game mechanics
Videos have done what no AI has ever done before. The system of OpenAI navigated the world of Micraft, swam, hunted and cooked the meat obtained. But the way there was by no means easy. Because the computer first had to learn the open game world and the necessary creativity.
For this purpose, OpenAI paid employees of an external service provider with 20 US dollars per hour. The tasks involved recording Minecraft videos and the associated keystrokes. Because videos available online usually only show what is possible in Minecraft and not how it works. 4,500 hours and $160,000 later, enough data was available.
Previous approaches have failed
Learning the game mechanics of Minecraft is by no means considered a new task. Three years ago, dozens of computer scientists competed at MineRL to solve a task: an AI was supposed to mine a diamond in the game. 660 people took part, nobody won.
It should come as no surprise to many that a computer can now play Minecraft. Nevertheless, solving the task is considered a big step for research. Machines should also learn human behavior in the coming years, since humans are not only based on logic. That is considered a big challenge.
