As part of the learning process they set up two bots, known as a dialog agents, to teach each other about human speech using machine learning algorithms.
The bots were originally left alone to develop their conversational skills.
The game contains more than 200 options based on male stereotypes such as alpha male, geek, urban male, metrosexual and more.
Players can customize his hair, clothing, and face, and also change his name.
However, some disagree with human’s ability to build intimate relationships with robots.
For example, Sherry Turkle, a professor of social studies of science and technology at MIT.
Earlier this year, the application upgraded its operating system to better model natural human expressions using improved animation techniques that create a more dynamic personality.The technology pushes forward the ability to create bots 'that can reason, converse and negotiate, all key steps in building a personalised digital assistant,' said researchers Mike Lewis and Dhruv Batra in a blog post.Facebook's Artificial Intelligence Researchers (Fair) team gave bots this ability by estimating the 'value' of an item and inferring how much that is worth to each party. In some cases, bots 'initially feigned interest in a valueless item, only to later 'compromise' by conceding it -- an effective negotiating tactic that people use regularly,' the researchers said.'Our interest was having bots who could talk to people,' Mike Lewis of Facebook's FAIR programme told Fast Co Design.Facebook's Artificial Intelligence Researchers (Fair) were teaching the chatbots, artificial intelligence programs that carry out automated one to one tasks, to make deals with one another.
