Building AI for Emotion Detection
Introduction Machines have been able to recognize and differentiate between faces for a few years now, but the human face has a purpose outside of identity. Mouths and eyebrows are vital to human communication and allow us to convey tone and emotion without the use of words or gestures. If machines gained the capability to interpret facial expressions into human emotion, it would open a whole new world of sentiment analysis. While the capability is obviously great, this task is hard for many humans to perform.
