A time-varying extension of the French-DeGroot model with decaying interpersonal influences
- Master Thesis
Fake news, memes and influencers are all part of the modern Internet landscape. They affect the opinions of individuals, which are one of the main drivers for human behaviour. Trying to understand how opinions emerge and develop inside a community would allow for more accurate predictions in global challenges such as financial crisis or migration. In this thesis, models of pairwise interactions based on a social network graph are reviewed. Models propagating in a social network have been proposed by many research groups, but they often lack a psychological basis. In this thesis an extension of the French-DeGroot model is proposed, which is motivated by an additional psychological aspect related to a person’s overestimation in his own belief. This model is then theoretically analysed, with results on the stability, convergence and consensus of the system. Finally, it was applied on a karate club data set, which suffered a division into two factions. It will be discussed whether the newly proposed model can accurately predict this split. Show more
