Simulations of group dynamics with different models

Kluver, J. and C. Stoica.

Abstract: A socio-matrix (or Moreno matrix) describes relations between members of a group. Such a matrix can also be used to predict the dynamics of a group, i.e., the behaviour of the group members is determined by the values of the matrix. Several different models are used to analyse group dynamics based on Moreno matrices, namely a cellular automaton (CA), a Kohonen feature map (KFM), an interactive neural net (IN), and a genetic algorithm (GA). The results of the different models are compared; the models produce rather similar effects. In addition the predictions of the models are compared with empirical observations with respect to groups of students and children
in a summer camp. The models are quite efficient in predicting real social behaviour.

I met Kluver at ICCS 2004. He gave another talk on modeling social roles with neural nets. (A different topic than the above paper).

The basic idea in his ICCS talk was that as an actor learns a set of responses to a set of perceived characteristics, an implicit role is formed. When interacting with a new counterparty with similar perceived characteristics, the net is already trained in a set of "appropriate" responses. Essentially it was a way of thinking about the abstraction of social roles over individuals filling those roles, as related to learning socially accepted behaviors. Without trying to get into details of what those behaviors might be (they are just abstract vectors of "response").
