Stochastic Variational Inference . I am a postdoctoral research scientist at the Columbia University Data Science Institute, working with David Blei. Matthew D. Hoffman, David M. Blei, Chong Wang, John Paisley; 14(4):1303−1347, 2013. Stochastic variational inference lets us apply complex Bayesian models to massive data sets. David Blei. Thus far, variational methods have mainly been explored in the parametric setting, in particular within the formalism of the exponential family (Attias 2000; Ghahramani and Beal 2001; Blei et al. Christian A. Naesseth Scott W. Linderman Rajesh Ranganath David M. Blei Linköping University Columbia University New York University Columbia University Abstract Many recent advances in large scale probabilistic inference rely on variational methods. We develop stochastic variational inference, a scalable algorithm for approximating posterior distributions. Machine Learning Statistics Probabilistic topic models Bayesian nonparametrics Approximate posterior inference. Recent advances allow such al-gorithms to scale to high dimensions.

Stochastic inference can easily handle data sets of this size and outperforms traditional variational inference, which can only handle a smaller subset. In this paper, we present a variational inference algorithm for DP mixtures. Cited by. 2003). Adapted from David Blei. Verified email at columbia.edu - Homepage. David M.
