Question: Relationship Between Action Units Intensity and Presence #1043
Hi, I thought action units will be considered as a presence when the intensity is big enough.
But in my data, for example, the Action Units 4:
When the intensity is 1.63, it is present (shown as "1"). But when the intensity is bigger than 1.63, even bigger than 2, it becomes absent (shown as "0"). I wonder why, or did I interpret the data in the wrong way? (Also, it is original data, I did not sort it in any way.)
