1. 1. Knowledge distillation for anomaly detection

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Nils Gustav Erik Pettersson; [2023]
   Keywords : ;

   Abstract : The implementation of systems and methodologies for time series anomaly detection holds the potential of providing timely detection of faults and issues in a wide variety of technical systems. Ideally, these systems are able to identify deviations from the normal behavior of systems even before any problems manifest, thus enabling proactive maintenance. READ MORE

3. 2. Unsupervised Anomaly Detection in Multivariate Time Series Using Variational Autoencoders

   University essay from Lunds universitet/Matematik LTH

   Author : Elias Aronsson; [2023]
   Keywords : Anomaly Detection; Variational Autoencoder VAE ; Unsupervised Learning; Machine learning; AI; Technology and Engineering;

   Abstract : In this master’s thesis, a novel unsupervised anomaly detection tool was developed in collaboration with Sandvik Rock Processing to assist engineers and experts in analyzing large amounts of sensor data from cone crushers used in the stone crushing industry. The tool focuses on analyzing power, pressure, and CSS sensor data. READ MORE

4. 3. Anomaly Detection in Wait Reports and its Relation with Apache Cassandra Statistics

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Abheyraj Singh Madhu; Sreemayi Rapolu; [2021]
   Keywords : Wait reports analysis; time-series anomaly detection; Apache Cassandra statistics; anomaly detection; behavior reporting tool;

   Abstract : Background: Apache Cassandra is a highly scalable distributed system that can handle large amounts of data through several nodes / virtual machines grouped together as Apache Cassandra clusters. When one such node in an Apache Cassandra cluster is down, there is a need for a tool or an approach that can identify this failed virtual machine by analyzing the data generated from each of the virtual machines in the cluster.

5. 4. A Concept for an Intrusion Detection System over Automotive Ethernet

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Hanna Lindwall; Pontus Ovhagen; [2020]
   Keywords : Intrusion Detection System; Deep Packet Inspection; Specification-based Detection; Anomaly-based Detection; V2G; Automotive Ethernet.; Technology and Engineering;

   Abstract : A modern automotive vehicle is a complex technical system, containing many electronic, mechanical, and software parts. Typically, a high-end vehicle contains 70 or more electronic control units (ECUs) on average. READ MORE

6. 5. Unsuperised Anomaly Detection : Methods and Application on Solvency 2 Technical Provisions

   University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

   Author : Richard Olofsson; [2020]
   Keywords : ;

   Abstract : This thesis work examines anomaly detection methods on large data sets related to insurance funds. Starting from requirements of low time complexity, ease of implementation and thorough definitions of contextual- and collective anomalies, different modelling frameworks are examined. READ MORE
