Next talk, Friday 19/3 at 1pm UK time:
Jeremias Knoblauch: Optimization-centric Generalizations of Bayesian Inference
Abstract: In this talk, I summarize some of the recent advances in thinking about Bayesian Inference as an optimization problem. I extensively cover the conceptual arguments underlying Generalized Variational Inference as a robust alternative to more conventional forms of Bayesian inference. Additionally, I briefly touch upon a range of other methodological theoretical advances, including Frequentist properties.
