With the rising success of deep neural networks, their reliability in terms of robustness (for example, against various kinds of adversarial examples) and confidence estimates becomes increasingly important. Bayesian neural networks promise to address these issues by directly modeling the uncertainty of the estimated network weights. In this article, I want to give a short introduction of training Bayesian neural networks, covering three recent approaches.
The Heidelberg Laureate Forum brings together young researchers and laureates in computer science and mathematics. During lectures, workshops, panel discussions and social events, the forum fosters personal and scientific exchange with other young researchers as well as laureates. I was incredibly lucky to have the opportunity to participate in the 7th Heidelberg Laureate Forum 2019. In this article, I want to give a short overview of the forum and share some of my impressions.
