TLDR
It is demonstrated that constant SGD gives rise to a new variational EM algorithm that optimizes hyperparameters in complex probabilistic models and a scalable approximate MCMC algorithm, the Averaged Stochastic Gradient Sampler is proposed.
Abstract
Stochastic Gradient Descent with a constant learning rate (constant SGD) simulates a Markov chain with a stationary distribution. With this perspective, we derive several new results. (1) We show t...

Inferring change points in the spread of COVID-19 reveals the effectiveness of interventions.

TL;DR: Modeling and Bayesian inference reveal the time dependence of SARS-CoV-2 interventions on the number of new infections using the example of Germany and the impact of these measures on the disease spread using change point analysis.

Deep Ensembles: A Loss Landscape Perspective

TL;DR: Developing the concept of the diversity--accuracy plane, it is shown that the decorrelation power of random initializations is unmatched by popular subspace sampling methods and the experimental results validate the hypothesis that deep ensembles work well under dataset shift.

Advances in Variational Inference

TL;DR: Variational inference (VI) as mentioned in this paper approximates a high-dimensional Bayesian posterior with a simpler variational distribution by solving an optimization problem, which has been successfully applied to various models and large-scale applications.
