Facebook deactivates robot after they developed own language

Facebook shut down a pair of its artificial intelligence robots after they invented their own, creepy language.

Researchers at Facebook Artificial Intelligence Research built a chatbot earlier this year that was meant to learn how to negotiate by mimicking human trading and bartering.

But when the social network paired two of the programs, nicknamed Alice and Bob, to trade against each other, they started to learn their own bizarre form of communication.

The chatbot conversation “led to divergence from human language as the agents developed their own language for negotiating,” the researchers said.

The two bots were supposed to be learning to trade balls, hats and books, assigning value to the objects then bartering them between each other.


But since Facebook’s team assigned no reward for conducting the trades in English, the chatbots quickly developed their own terms for deals.

“There was no reward to sticking to English language,” Dhruv Batra, Facebook researcher, told FastCo. “Agents will drift off understandable language and invent codewords for themselves.

“Like if I say ‘the’ five times, you interpret that to mean I want five copies of this item. This isn’t so different from the way communities of humans create shorthands.”
