Abstract

[fr] Social Signal Processing is a new interdisciplinary domain of research whose end goal is to equip
machines with social intelligence, a facet of intelligence only known to mankind. As life happens
in groups, it is essential that machines understand how human groups function to be able to
collaborate with them in the future. One important aspect of group life is group cohesion. In
the social sciences literature, several definitions of cohesion exist. In our work, we use Severt and
Estrada’s integrative framework of cohesion. Recently, Maman et al. developed a computational
model of cohesion called fItG that automatically predict the dynamics of cohesion. However, this
model uses all interaction timestamps equally, without dynamically giving each of them a certain
importance.
In this work, we develop attention-based versions of fItG. We compare their performances with the
original fItG model through permutation tests of their F1-scores
