The observation of tolerance in social network models

by Kristen Lund , 2010
"... This paper defines the phenomenon of tolerance in social network models, focusing on the HRN and HWR rules. We will seek to develop a mathematical model for tolerance and thus clearly define the factors that contribute toward tolerance in agents. Several experiments will be run on social network mod ..."

Social Network Models for the TDR System

by Yingjie Tang , Haoran Zhang , Zhijian Liang , Shi-Kuo Chang
"... Abstract-The TDR system is an experimental multi-level slow intelligence system for personal health care. The TDR system can be used by a single user or a group of users who will interact to understand, maintain and improve each other's state of health. In this paper, we simulate social networ ..."

networks by applying the Abstract Machine model. Two social network models are described: the Circulated Model and the Teacher Student Model. We have incorporated the Teacher Student Model into the Chi super-component of the TDR system and obtained positive experimental results. Keywords-Personal health

A Strategic Model of Social and Economic Networks

by Matthew O. Jackson, Asher Wolinsky - CMSEMS Discussion Paper 1098, Northwestern University, revised , 1995
"... We study the stability and efficiency of social and economic networks, when selfinterested individuals can form or sever links. First, for two stylized models, we characterize the stable and efficient networks. There does not always exist a stable network that is efficient. Next, we show that this t ..."

Goodness of fit of social network models

by David R Hunter , Steven M Goodreau , Mark S Handcock - Journal of the American Statistical Association , 2008
"... We present a systematic examination of a real network data set using maximum likelihood estimation for exponential random graph models as well as new procedures to evaluate how well the models fit the observed networks. These procedures compare structural statistics of the observed network with the ..."

geometrically weighted edgewise shared partner, geometrically weighted dyadic shared partner, and geometrically weighted degree network statistics. We conclude that these models capture aspects of the social structure of adolescent friendship relations not represented by previous models.

Empiricism for descriptive social network models

by Camille Roth A
"... Social complex system modeling is at the core of a recent interdisciplinary effort, in which statistical physics has been playing a notable role; yet, the unfrequent val-idation of behavioral hypotheses possibly leads to normative rather than descrip-tive models, plausibly less appealing to social s ..."

scientists. An epistemological insight and hindsight on this whole program is proposed, emphasizing a strong empirical methodology which extends to low-level agent-based dynamics. Special attention is given to the recent interest in knowledge diffusion models. Key words: social network models, epistemology

Maximizing the Spread of Influence Through a Social Network

by David Kempe - In KDD , 2003
"... Models for the processes by which ideas and influence propagate through a social network have been studied in a number of domains, including the diffusion of medical and technological innovations, the sudden and widespread adoption of various strategies in game-theoretic settings, and the effects of ..."

The structure and function of complex networks

by M. E. J. Newman - SIAM REVIEW , 2003
"... Inspired by empirical studies of networked systems such as the Internet, social networks, and biological networks, researchers have in recent years developed a variety of techniques and models to help us understand or predict the behavior of these systems. Here we review developments in this field, ..."

The Evolution of Social and Economic Networks

by Matthew O. Jackson, Alison Watts - JOURNAL OF ECONOMIC THEORY 106, 265–295 , 2002
"... We examine the dynamic formation and stochastic evolution of networks connecting individuals. The payoff to an individual from an economic or social activity depends on the network of connections among individuals. Over time individuals form and sever links connecting themselves to other individuals ..."

The spread of obesity in a large social network over 32 years

by Nicholas A. Christakis, James H. Fowler - NEW ENGLAND JOURNAL OF MEDICINE , 2007
"... The prevalence of obesity has increased substantially over the past 30 years. We performed a quantitative analysis of the nature and extent of the person-to-person spread of obesity as a possible factor contributing to the obesity epidemic. Methods We evaluated a densely interconnected social networ ..."

network of 12,067 people assessed repeatedly from 1971 to 2003 as part of the Framingham Heart Study. The body-mass index was available for all subjects. We used longitudinal statistical models to examine whether weight gain in one person was associated with weight gain in his or her friends, siblings

Mining the Network Value of Customers

by Pedro Domingos, Matt Richardson - In Proceedings of the Seventh International Conference on Knowledge Discovery and Data Mining , 2002
"... One of the major applications of data mining is in helping companies determine which potential customers to market to. If the expected pro t from a customer is greater than the cost of marketing to her, the marketing action for that customer is executed. So far, work in this area has considered only ..."

as a set of independent entities, we view it as a social network and model it as a Markov random eld. We show the advantages of this approach using a social network mined from a collaborative ltering database. Marketing that exploits the network value of customers|also known as viral marketing
