Robust Projection based Anomaly Extraction (RPE) in Univariate Time-Series

Mostafa Rahmani, Anoop Deoras, Laurent Callot

This paper presents a novel, closed-form, and data/computation efficient online anomaly detection algorithm for time-series data. The proposed method, dubbed RPE, is a window-based…

Testing Granger Non-Causality in Panels with Cross-Sectional Dependencies

Lenon Minorics, Caner Turkmen, David Kernert +3

This paper proposes a new approach for testing Granger non-causality on panel data. Instead of aggregating panel member statistics, we aggregate their corresponding p-values and sh…

Online Time Series Anomaly Detection with State Space Gaussian Processes

Christian Bock, François-Xavier Aubet, Jan Gasthaus +3

We propose r-ssGPFA, an unsupervised online anomaly detection model for uni- and multivariate time series building on the efficient state space formulation of Gaussian processes. F…

Improve black-box sequential anomaly detector relevancy with limited user feedback

Luyang Kong, Lifan Chen, Ming Chen +2

Anomaly detectors are often designed to catch statistical anomalies. End-users typically do not have interest in all of the detected outliers, but only those relevant to their appl…

A simple and effective predictive resource scaling heuristic for large-scale cloud applications

Valentin Flunkert, Quentin Rebjock, Joel Castellon +2

We propose a simple yet effective policy for the predictive auto-scaling of horizontally scalable applications running in cloud environments, where compute resources can only be ad…
