Intrinsic Anomaly Detection for Multi-Variate Time Series

Autor: Rabanser, Stephan, Januschowski, Tim, Rasul, Kashif, Borchert, Oliver, Kurle, Richard, Gasthaus, Jan, Bohlke-Schneider, Michael, Papernot, Nicolas, Flunkert, Valentin

We introduce a novel, practically relevant variation of the anomaly detection problem in multi-variate time series: intrinsic anomaly detection. It appears in diverse practical scenarios ranging from DevOps to IoT, where we want to recognize failures

Multi-Objective Model Selection for Time Series Forecasting

Autor: Borchert, Oliver, Salinas, David, Flunkert, Valentin, Januschowski, Tim, Günnemann, Stephan

Research on time series forecasting has predominantly focused on developing methods that improve accuracy. However, other criteria such as training time or latency are critical in many real-world applications. We therefore address the question of how

Natural Posterior Network: Deep Bayesian Uncertainty for Exponential Family Distributions

Autor: Charpentier, Bertrand, Borchert, Oliver, Zügner, Daniel, Geisler, Simon, Günnemann, Stephan

Uncertainty awareness is crucial to develop reliable machine learning models. In this work, we propose the Natural Posterior Network (NatPN) for fast and high-quality uncertainty estimation for any task where the target distribution belongs to the ex
