Interpretable Anomaly Detection in Cellular Networks by Learning Concepts in Variational Autoencoders

no code implementations28 Jun 2023 Amandeep Singh, Michael Weber, Markus Lange-Hegermann

This paper addresses the challenges of detecting anomalies in cellular networks in an interpretable way and proposes a new approach using variational autoencoders (VAEs) that learn interpretable representations of the latent space for each Key Performance Indicator (KPI) in the dataset.

Automated Focal Loss for Image based Object Detection

no code implementations19 Apr 2019 Michael Weber, Michael Fürst, J. Marius Zöllner

With automated focal loss we introduce a new loss function which substitutes this hyperparameter by a parameter that is automatically adapted during the training progress and controls the amount of focusing on hard training examples.

MultiNet: Real-time Joint Semantic Reasoning for Autonomous Driving

16 code implementations22 Dec 2016 Marvin Teichmann, Michael Weber, Marius Zoellner, Roberto Cipolla, Raquel Urtasun

While most approaches to semantic reasoning have focused on improving performance, in this paper we argue that computational times are very important in order to enable real time applications such as autonomous driving.
