متن کاملEntropic Regularization of Mixed-membership Network Models using Pseudo-observations
Mixed-membership network models permit a node in a graph to take on different latent roles in different interactions. However, while mixed-membership block models often do out-perform classical network models, the actual degree of mixed-membership in many graphs is small, with nodes usually taking on only a handful of many possible roles. We thus present a novel slightly mixed membership stocha...

متن کاملDiscussion of "The Discrete Infinite Logistic Normal Distribution for Mixed-Membership Modeling"
Mixed-membership models (e.g. “topic models”) are inarguably popular; especially latent Dirichlet allocation (LDA) [Blei et al., 2003] and its variants. Such models have become a fundamental tool in the analysis and exploration of many types of data. Originally designed to model text documents as per-word draws from a document-specific weighting of a finite collection of “topics” (distributions...
