A ‘human-like’ bot built by scientists at Facebook’s Artificial intelligence lab has been trained by watching hundreds of videos of Skype conversations. The bots are driven by an artificially intelligent algorithm that helps them to learn and mimic humans’ expressions and responses while communicating with each other.

With an intention to optimize its learning, researcher designed the algorithm in such a way that it splits the human face into 68 key points that it monitored throughout each Skype conversation, the research that Facebook would present at the International Conference on Intelligent Robots and Systems in Vancouver, Canada, from September 24-28.

This practice made system learned to do acts like naturally producing nods, blinks and various mouth movements to show they are engaged with the person they are talking to.

Gradually, The bot also learned speaking like humans and choose in real time what the most appropriate facial response would be.

“The Facebook team then tested the system with panels of people who watched animations that included both the bot reacting to a human, and a human reacting to a human. The volunteers judged the bot and the human to be equally natural and realistic,” the results said.

Just for a note, In July, Facebook shut down one of its AI systems after chatbots automatically started the conversation in their own language (not understandable by human beings) defying the codes provided. The social media giant had to pull the plug on the AI system that its researchers were working on “because things got out of hand”.
