    Nyckelord :unsupervised; online; anomaly detection; explainable ai; machine learning; mahalanobis distance;

    Sammanfattning : This research aims to identify a method for unsupervised online anomaly detection in multivariate time series in dynamic systems in general and on the case study of Devwards IoT-system in particular. A requirement of the solution is its explainability, online learning and low computational expense. LÄS MER

  4. 8. Ability Estimation Methods : An Introduction to Item Response Theory and Elo Education Systems

    Kandidat-uppsats, Stockholms universitet/Statistiska institutionen

    Författare :Sebastian Hedberg; Salma Nasra; [2023]
    Nyckelord :;

    Sammanfattning : The foundational testing of knowledge and ability is and has always been very important. These days we can create a computerized test that can vary based on the estimated skill of the examinee. This is called an adaptive test. And the aim of this is to estimate the ability of the examinee more precisely. LÄS MER

  7. 10. Anomaly Detection in the EtherCAT Network of a Power Station : Improving a Graph Convolutional Neural Network Framework

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Niklas Barth; [2023]
    Nyckelord :Unsupervised Learning; Multivariate Time Series; Graph Convolutional Neural Networks; Anomaly Detection; Industrial Control System; EtherCAT; Power Station; Electricity Grid;

    Sammanfattning : In this thesis, an anomaly detection framework is assessed and fine-tuned to detect and explain anomalies in a power station, where EtherCAT, an Industrial Control System, is employed for monitoring. The chosen framework is based on a previously published Graph Neural Network (GNN) model, utilizing attention mechanisms to capture complex relationships between diverse measurements within the EtherCAT system.
