Solution Simplex Clustering for Heterogeneous Federated Learning

no code implementations5 Mar 2024 Dennis Grinwald, Philipp Wiesner, Shinichi Nakajima

We tackle a major challenge in federated learning (FL) -- achieving good performance under highly heterogeneous client distributions.

Clustering Federated Learning

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.

FedZero: Leveraging Renewable Excess Energy in Federated Learning

1 code implementation24 May 2023 Philipp Wiesner, Ramin Khalili, Dennis Grinwald, Pratik Agrawal, Lauritz Thamsen, Odej Kao

Federated Learning (FL) is an emerging machine learning technique that enables distributed model training across data silos or edge devices without data sharing.

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.

Anomaly Detection

A Taxonomy of Anomalies in Log Data

no code implementations26 Nov 2021 Thorsten Wittkopp, Philipp Wiesner, Dominik Scheinert, Odej Kao

In this paper, we present a taxonomy for different kinds of log data anomalies and introduce a method for analyzing such anomalies in labeled datasets.

Unsupervised Anomaly Detection

LogLAB: Attention-Based Labeling of Log Data Anomalies via Weak Supervision

no code implementations2 Nov 2021 Thorsten Wittkopp, Philipp Wiesner, Dominik Scheinert, Alexander Acker

With increasing scale and complexity of cloud operations, automated detection of anomalies in monitoring data such as logs will be an essential part of managing future IT infrastructures.
