Bayesian (Deep) Learning / Uncertainty

Topics: Bayesian (Deep) Learning, Uncertainty, Probabilistic Models, (Implicit) Generative Models

Probabilistic modeling is a useful tool to analyze and understand real-world data, specifically enabling to represent the uncertainty inherent to the data and the learned model. In our research we study principle for (efficient) probabilisitc inference as well as applications of probabilistic models (often focusing on non-i.i.d. data scenarios). Specifically we also consider the combination of neural networks and Bayesian modelling -- often called "Bayesian Deep Learning" --, for example, by investigating principles for neural variational inference or deep generative models.
