How to Configure Masked Event Anomaly Detection on Software Logs?
Jesse Nyyssölä, Mika Mäntylä, Martín Varela
Software Log anomaly event detection with masked event prediction has various technical approaches with countless configurations and parameters. Our objective is to provide a basel…
Pinpointing Anomaly Events in Logs from Stability Testing -- N-Grams vs. Deep-Learning
Mika Mäntylä, Martín Varela, Shayan Hashemi
As stability testing execution logs can be very long, software engineers need help in locating anomalous events. We develop and evaluate two models for scoring individual log-event…
From QoS Distributions to QoE Distributions: a System's Perspective
Tobias Hossfeld, Poul E. Heegaard, Martin Varela +2
In the context of QoE management, network and service providers commonly rely on models that map system QoS conditions (e.g., system response time, paket loss, etc.) to estimated e…
Confidence Interval Estimators for MOS Values
Tobias Hossfeld, Poul E. Heegaard, Martin Varela +1
For the quantification of QoE, subjects often provide individual rating scores on certain rating scales which are then aggregated into Mean Opinion Scores (MOS). From the observed…
Formal Definition of QoE Metrics
Tobias Hossfeld, Poul E. Heegaard, Martin Varela +1
This technical report formally defines the QoE metrics which are introduced and discussed in the article "QoE Beyond the MOS: An In-Depth Look at QoE via Better Metrics and their R…
Single-sided Real-time PESQ Score Estimation
Sebastián Basterrech, Gerardo Rubino, Martín Varela
For several years now, the ITU-T's Perceptual Evaluation of Speech Quality (PESQ) has been the reference for objective speech quality assessment. It is widely deployed in commercia…
