Bistability through Triadic Closure
We propose and analyse a class of evolving network models suitable for describing a dynamic topological structure. Applications include telecommunication, on-line social behaviour and information processing in neuroscience. We model the evolving network as a discrete time Markov chain, and study a very general framework where, conditioned on the current state, edges appear or disappear independ...
متن کاملHomophily and Triadic Closure in Evolving Social Networks
We present a new network model accounting for homophily and triadic closure in the evolution of social networks. In particular, in our model, each node is characterized by a number of features and the probability of a link between two nodes depends on common features. The bipartite network of the actors and features evolves according to a dynamics that depends on three parameters that respectiv...
متن کاملOn the Relation of Strong Triadic Closure and Cluster Deletion
We study the parameterized and classical complexity of two related problems on undirected graphs G = (V,E). In Strong Triadic Closure we aim to label the edges in E as strong and weak such that at most k edges are weak and G contains no induced P3 with two strong edges. In Cluster Deletion, we aim to destroy all induced P3s by a minimum number of edge deletions. We first show that Strong Triadi...
متن کاملUncovering the Formation of Triadic Closure in Social Networks
The triad is one of the most basic human groups in social networks. Understanding factors affecting the formation of triads will help reveal the underlying mechanisms that govern the emergence and evolution of complex social networks. In this paper, we study an interesting problem of decoding triadic closure in social networks. Specifically, for a given closed triad (a group of three people who...
متن کاملA Will Triadic Closure Strengthen Ties in Social Networks?
The social triad—a group of three people—is one of the simplest and most fundamental social groups. Extensive network and social theories have been developed to understand its structure, such as triadic closure and social balance. Over the course of a triadic closure—the transition from two ties to three among three users, the strength dynamics of its social ties, however, are much less well un...
