【当机器人有了自己的语言  或许人类需要个翻译】来自 Elon Musk 人工智能实验室的科学家们正在训练人工智能形成自己的语言体系,并希望能借此实现彼此的交流完成简单的任务。团队创造了一个简单的二维空间,两台 AI 必须通过试错找到对方可接受的语言指令,到达指定的区域。当场景变得复杂时,AI 就可以将词汇和对象连接起来,形成稳定的概念。团队表示,当机器人的语言系统更加复杂时,将会有一个翻译机器人可以将机器人之间的交流转化为人类语言。

Robochat: Robots are learning to talk in a completely new language (and humans will need a translator)

By PHOEBE WESTON FOR MAILONLINE

Robots have communicated with each other using a shared language they made up as they went along in an amazing new experiment.

Experts at Elon Musk's artificial intelligence lab have taught robots to start their own language so they could help each other complete simple tasks.

In the future, researchers hope that as the language becomes more complex they will have a 'translator bot' who will be able to convert robot chat into English.

The team at OpenAI, which is the artificial intelligence lab created by Tesla founder Elon Musk based in San Francisco, created a world where robots learnt a language that enabled them to complete simple tasks - such as moving themselves from A to B.

Experts created a two dimensional world to navigate and the robots - or agents - which were green, red and blue circles had to find their way around.

The robots relied on a technique called reinforcement learning - which involved them trialling different sounds and seeing which ones helped them complete a task and which didn't.

They taught agents to create language by 'dropping them into a set of simple worlds, giving them the ability to communicate, and then giving them goals that can be best achieved by communicating with other agent', the team said in a blog post.

If they achieve a goal, then they get rewarded.

'We train them using reinforcement learning and, due to careful experiment design, they develop a shared language to help them achieve their goals', they said.

This means that a speaker would for example start to form an association between the word 'house' and the image of a house.

As they build up their vocabulary they can start using sentences that allow them to convey ideas to one another, writes Wired.com.

As the language becomes more complex, experts hope they will be able to translate what they are saying into English.

The team gave the robots two types of actions - one environment action such as looking at something and communication actions, such as broadcasting a word to one of the other agents.

Robots were able to modify their messages to improve the effectiveness of communication.

For example if an agent realises it could have performed something better had it had supplementary information he will communicate this information to the next agent so its instructions are as clear as possible.

The team found that agents were able to evolve languages to fit the situation and able to accomplish tasks by communicating with one another.

'We hope that this research into growing a language will let us develop machines that have their own language tied to their own lived experience', the researcher wrote.

'We think that if we slowly increase the complexity of their environment, and the range of actions the agents themselves are allowed to take, it's possible they'll create an expressive language which contains concepts beyond the basic verbs and nouns that evolved here.'
