---++ Department of Biostatistics Seminar/Workshop Series ---+ Scaling Bayes: Probabilistic Modeling for Large Models and Datasets <span style="background-color: transparent; color: #339900; font-size: 20.3px;">Chris Fonnesbeck, !PhD</span><span style="background-color: transparent; color: #339900; font-size: 20.3px;">, Assistant Professor, Department of Biostatistics, Vanderbilt University Medical Center</span> Bayesian models are appealing to practitioners because they are flexible, they automatically account for uncertainty in inferences and predictions, and their outputs are straightforward to interpret by non-expert users. However, fitting such models typically requires computationally-intensive algorithms (e.g. Markov chain Monte Carlo) that have traditionally scaled poorly with either the size of the model or the quantity of data used to fit the model. In the past several years there have been important innovations in Bayesian approximation methods that make working with large models and datasets feasible. I will provide an overview of some of these methods, and their implementation in new software tools using open source computational backends, including Theano (via PyMC3) and TensorFlow (via Edward and GPflow).
