Karasu: A Collaborative Approach to Efficient Cluster Configuration for Big Data Analytics

no code implementations22 Aug 2023 Dominik Scheinert, Philipp Wiesner, Thorsten Wittkopp, Lauritz Thamsen, Jonathan Will, Odej Kao

However, big data analytics jobs across users can share many common properties: they often operate on similar infrastructure, using similar algorithms implemented in similar frameworks.

PULL: Reactive Log Anomaly Detection Based On Iterative PU Learning

no code implementations25 Jan 2023 Thorsten Wittkopp, Dominik Scheinert, Philipp Wiesner, Alexander Acker, Odej Kao

Due to the complexity of modern IT services, failures can be manifold, occur at any stage, and are hard to detect.
