Facebook has reportedly stopped two AI chatbots, Alice and Bob after they started speaking the language of their own. The two bots were assumed to be conversing with each other in English. But their language wasn’t understandable by the scientists who were doing an experiment on them.
Alice and Bob were created earlier this year by Facebook Research Team and they were functioned to imitate trading and barter system. Basically, they were aiming to negotiate with each other but when were paired to each other, the two started to talk in their odd and unusual language.
To everyone’s surprise, chatbots ending up in doing this kind of chat because no rewards were assigned for this trade. So when there’s no reward for bartering, Alice and Bob invented codewords to talk to each other. According to Facebook researcher Druv Batra, “There was no reward for sticking to English language, 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.” Batra further explained that sentences said by bots could not be cracked by scientists. “It’s important to remember, there aren’t bilingual speakers of AI and human languages,” said Batra.
Facebook term this incident an important milestone towards achieving the goal of a personlized digital assistant. Another interesting outcome of this experiment was that most of the people didn’t realize that they are talking to a bot.
