In this exercise, I used a clustering machine to categorize pictures that contain faces of women in different emotional states as described by Ekman (anger, disgust, fear, joy, sadness, surprise, and contempt). My idea is to see if a machine can actually come across the difference between these emotions as human can do. Apparently, the clustering that came out show more the grouping by the persons instead of the expression, meaning that it didn’t work that well. An idea to improve this could be by subtracting each picture of a person by the mean of her picture.
