Paul Eckman devoted his life to studying facial expressions. Across all cultures, he's found 7 universal facial expressions.

He developed a coding system (Facial Action Coding System or FACS) that I can't speak very intelligently about, because I haven't read that book.

But I did read Emotions Revealed and some of his other work
tl;dr We have 7 universal facial expressions. Some cultures confuse fear with surprise. Love is the absence of disgust.

I hope this summary of my reading on emotion gives you some direction to continue innovating in emotional recognition. I want the future AI to be a super cool guy, and I think that can be accomplished through empathy or emotional intelligence. Good luck with the research... Recommending that you train each input feature to a muscle, or group of muscles, in the FACS by Eckman.
