Blockmodels with maximum concentration
There are many circumstances in which binary relations are defined between pairs of objects: in sociology there are social relations between people; in business there are trading relations between firms; in design there are functional dependencies between components. In all of these the clustering of objects into densely interconnected blocks reveals something of the structure of the system. In...
متن کامل1 Blockmodels
Professionals can be rewarded in different ways. The most common type of reward is provided by the market, that is, by successfully selling one’s products or services to consumers. In professional fields dealing with the production of knowledge, art, et cetera, market success is usually just one type of reward for professionals and not necessarily the most important one. Especially recognition ...
متن کاملBuilding stochastic blockmodels
The literature devoted to the construction of stochastic blockmodels is relatively rare compared to that of the deterministic variety. In this paper, a general definition of a stochastic blockmodel is given and a number of techniques for building such blockmodels are presented. In the statistical approach, the likelihood ratio statistic provides a natural index to evaluate the fit of the model ...
متن کاملStochastic blockmodels with growing number of classes
Latent variable models are frequently used to identify structure in dichotomousnetwork data, in part because they give rise to a Bernoulli product likelihood thatis both well understood and consistent with the notion of exchangeable randomgraphs. In this article we propose conservative confidence sets that hold with re-spect to these underlying Bernoulli parameters as a function...
متن کاملMixed Membership Stochastic Blockmodels
Observations consisting of measurements on relationships for pairs of objects arise in many settings, such as protein interaction and gene regulatory networks, collections of author-recipient email, and social networks. Analyzing such data with probabilisic models can be delicate because the simple exchangeability assumptions underlying many boilerplate models no longer hold. In this paper, we ...
