Facebook is teaching robots how to express themselves just like humans

Artificial Intelligence Lab (AI) of the world's largest social media company Facebook has developed a bot that can analyze the facial expressions of the people it interacts with Customize yourself appropriately with the human face.

It is controlled by a deep neural network . This neural network integrates video data of 250 video recorded Skype conversations between two people together as part of the training process.

The researchers identified 68 "face molds" to detect subtle and micro-facial expressions on the human face.

"Although the human faces in our dataset are different, their expressions have similarities that can be derived from the facial features , " Facebook's scientists explain. in an article published in New Scientist.

For example, when people grope something, the profile of their eyebrows and mouth reveal the most about their emotional state. "

Later, the scientists conducted a test of the bot's response to a group of people.

Bots are asked to "look at how their facial expressions respond to the user, especially the face image must be natural, appropriate and social" and decide whether or not to participate in the conversation.

The results show that the bot has passed this test with the decision to choose facial expressions in a "natural and confident way" as well as "real life".

Researchers say that the human subjects involved in interacting with bots are becoming increasingly common in many areas of application such as education, health care and personal assistance.

Scientists say the next step in bot training is to get it to interact with real people in the real world.
