Hi Folks,
This Friday Alp Kucukelbir, formerly at Yale, now at Columbia, by way of
Princeton, will talk about:
TITLE: Population Empirical Bayes
ABSTRACT: When a model does not match the data, predictive accuracy
suffers. To mitigate this effect, we develop population empirical Bayes a
hierarchical framework that incorporates the empirical population
distribution
of data into Bayesian analysis. We efficiently apply this method to
complex
models by proposing a stochastic variational inference algorithm. We
demonstrate
improved predictive accuracy over classical Bayesian inference in three
models:
a Bayesian linear regression of health data, a Bayesian mixture model of
image
histograms, and a latent Dirichlet allocation topic model of a text corpus.
See you Friday at 11am in the Stat's classroom.
Regards,
sekhar
