David Blei1 blei@princeton.edu 1 Department of Computer Science, Princeton University, Princeton, NJ, USA 2 Department of Electrical & Computer Engineering, Duke University, Durham, NC, USA Abstract We present a variational Bayesian inference al-gorithm for the stick-breaking construction of the beta process. We assume additional parameters ↵ that are ﬁxed. Their work is widely used in science, scholarship, and industry to solve interdisciplinary, real-world problems. It posits a family of approximating distributions qand ﬁnds the closest member to the exact posterior p. Closeness is usually measured via a divergence D(qjjp) from qto p. While successful, this approach also has problems. History 21/49 I Idea adapted fromstatistical physics{ mean- eld methods to t a neural network (Peterson and Anderson, 1987). (We also show that the Bayesian nonparametric topic model outperforms its parametric counterpart.) Title: Hierarchical Implicit Models and Likelihood-Free Variational Inference.

Lafferty LAFFERTY@CS.CMU.EDU School of Computer Science, Carnegie Mellon University, Pittsburgh PA 15213, USA Abstract A family of probabilistic time series models is developed to analyze the time evolution of topics in large document collections. 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.
