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. My research interests include approximate statistical inference, causality and artificial intelligence as well as their application to the life sciences.

(We also show that the Bayesian nonparametric topic model outperforms its parametric counterpart.) 2003). t) á x 2) t log(x 1)+(1! Variational Inference David M. Blei 1Setup • As usual, we will assume that x = x 1:n are observations and z = z 1:m are hidden variables. I am a postdoctoral research scientist at the Columbia University Data Science Institute, working with David Blei. Stochastic inference can easily handle data sets of this size and outperforms traditional variational inference, which can only handle a smaller subset.

Closeness is usually measured via a divergence D(qjjp) from qto p. While successful, this approach also has problems. Stochastic variational inference lets us apply complex Bayesian models to massive data sets.
