AffectiveTDA: Using Topological Data Analysis to Improve Analysis and Explainability in Affective Computing

Fig. 1. Our affective computing visualization provides numerous options for comparing and contrasting the data. For example, the small multiples view (left) is comparing a male (left) subject to a female (right) subject considering different subsets of facial landmarks (columns), across emotions (rows) of anger , disgust, fear , happiness, sadness, and surprise. Each point represents one facial pose. The embedding graph (top right) compares all facial poses across all emotions, in this case showing the female full face using MDS on non-metric topology. The 3D landmarks (lower right) show a single facial pose per emotion. Settings are selected on the bottom.
