Book ChapterDOI
Bayesian Nonnegative Matrix Factorization with Stochastic Variational Inference
TL;DR: Blei and Lafferty as discussed by the authors presented stochastic variational inference algorithms for two Bayesian nonnegative matrix factorization (NMF) models, which allow for fast processing of massive datasets.

Recurrent switching linear dynamical systems
Scott W. Linderman,Andrew Miller,Ryan P. Adams,David M. Blei,Liam Paninski,Matthew J. Johnson +5 more
TL;DR: A new model class is presented that not only discovers these dynamical units, but also explains how their switching behavior depends on observations or continuous latent states, something that traditional SLDS models fail to do.
Journal ArticleDOI
The Discrete Innite Logistic Normal Distribution
TL;DR: The discrete innite logistic normal distribution (DILN) as mentioned in this paper generalizes the hierarchical Dirichlet process (HDP) to model correlation structure between the weights of the atoms at the group level.

Computer method and apparatus for segmenting text streams
Pedro J. Moreno,David M. Blei +1 more
TL;DR: In this article, a probability member provides working probabilities that a group of words is of a topic selected from a plurality of predetermined topics, and a processing module determines probability of certain words in the input text stream being of a same topic.
BookDOI
Statistical Network Analysis: Models, Issues, and New Directions
Edoardo M. Airoldi,David M. Blei,Stephen E. Fienberg,Anna Goldenberg,Eric P. Xing,Alice X. Zheng +5 more
TL;DR: In this paper, a detailed survey of machine learning methods for classification in networked data and an application to Suspicion Scoring is presented, along with a detailed analysis of a dynamic social network built from PGP Keyrings.
