Alice and Bob, the names of the two chatbots, use artificial intelligence that aims to learn to negotiate by mimicking the process of selling, buying, and bartering like humans.
But when Alice and Bob were paired up to negotiate each other, the two turned out to be conversing in their own language. They originally did use human language, but they then developed their own language.
Both bots should learn to exchange balls, hats, and books. They must value each object, then practice bartering between the two, according to the Telegraph
Unfortunately, Facebook's research team does not require that the exchange should be done in English. As a result the negotiation process was not running properly and both bots were forced to shut down because humans can not understand what they are talking.
"There is no prize for using English, so bot agents move from understandable language and create code that they only understand," said Dhruv Batra, Facebook researcher.
