1. Anomaly Detection in the EtherCAT Network of a Power Station : Improving a Graph Convolutional Neural Network Framework
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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.

2. Generating Extreme Value Distributions in Finance using Generative Adversarial Networks
University essay from KTH/Matematik (Avd.)Abstract : This thesis aims to develop a new model for stress-testing financial portfolios using Extreme Value Theory (EVT) and General Adversarial Networks (GANs). The current practice of risk management relies on mathematical or historical models, such as Value-at-Risk and expected shortfall. READ MORE

3. Estimation of severe crash frequency using two surrogates
University essay from Lunds universitet/Matematisk statistikAbstract : This thesis is concerned with the estimation of crash frequency based on the bivariate modeling of surrogate measures of safety (SMoS), which serve as indicators for traffic risk. Using the SMoS, any traffic conflict between two road users can be described by their proximity together with their hypothetical consequence. READ MORE

4. Forecasting Exchange Rate Value-at-Risk and Expected Shortfall: A GARCH-EVT Approach
University essay from Lunds universitet/Nationalekonomiska institutionenAbstract : This thesis aims to investigate the accuracy of Value-at-Risk and Expected Shortfall forecasts of various GARCH-type models based on five currency exchange rate pairs. The GARCH models are employed under different conditional distributional assumptions, and extended using the two-stage Extreme Value Theory (EVT) approach of McNeil and Frey (2000). READ MORE

5. Value at Risk and Expected Shortfall risk measures using Extreme Value Theory
University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistikAbstract : Calculating risk measures as Value at Risk (VaR) and Expected Shortfall (ES) has become popular for institutions and agents in financial markets. A main drawback with these risk measures is that they traditionally assume a specific distribution, as the Normal distribution or the Student’s t distribution. READ MORE
