Missing Social activity classes

[suminlee94]

Thank you for sharing your codes and annotations.
I found that social activity annotation labels are quite different from reported labels in the paper.
There are 11 social activity classes in the Fig 3 of the paper.
But in 'group.pbtxt' files, first 27 classes which are same as individual action classes,
and only 5 new social activity classes which are 'chatting', 'working together', "join/leave/expansion/narrow", "human object interaction", and "complicated".
Most of the classes reported in the paper are missing.

Considering single-person group, the number of social activity classes should be 27 (inidvidual action) + 11 (social activity) = 36.
But there are only 32.

Do I miss something???
