What Does Other Mean?

Expressions that make up less than 5% of the sum of all expression intensities are included in the category Other. The example below shows part of the detailed log of an analysis. For each expression, the total intensity is calculated. Angry, Surprised, Scared and Disgusted each have a total intensity of less than 5% of the sum of all intensities. The sum of these four expressions is displayed as Other in the Expression summary.
