  1. 1. Neural Network-based Anomaly Detection Models and Interpretability Methods for Multivariate Time Series Data

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Deepthy Prasad; Swathi Hampapura Sripada; [2023]
    Nyckelord :multivariate - time series; anomaly detection; neural networks; autoencoders; interpretability; counterfactuals;

    Sammanfattning : Anomaly detection plays a crucial role in various domains, such as transportation, cybersecurity, and industrial monitoring, where the timely identification of unusual patterns or outliers is of utmost importance. Traditional statistical techniques have limitations in handling complex and highdimensional data, which motivates the use of deep learning approaches. LÄS MER

  2. 2. An Application of LatentCF++ on Providing Counterfactual Explanations for Fraud Detection

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Maria-Sofia Giannopoulou; [2023]
    Nyckelord :counterfactuals; fraud detection; LatentCF ; autoencoder; one-dimensional convolutional neural network;

    Sammanfattning : The aim of explainable machine learning is to aid humans in understanding how exactly complex machine learning models work. Machine learning models have offered great performance in various areas. However, the mechanisms behind how the model works and how decisions are being made remain unknown. LÄS MER

  3. 3. Counterfactual explanations for time series

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Markus Schultz; [2022]
    Nyckelord :Time Series; Counterfactual; Model Agnostic; Machine Learning; Classification;

    Sammanfattning : Time Series are used in healthcare, meteorology, and many other fields. Rigorous research has been done to develop distance measures and classifying algorithms for time series. When a time series is classified, one can ask what changes should be made to the time series to classify it differently. LÄS MER

  4. 4. The Economic Effect of Membership in the European Union – The Case of Sweden : Using the Synthetic Control Method and Difference-in-Differences Method

    Magister-uppsats, Högskolan Dalarna/Institutionen för kultur och samhälle

    Författare :Agnes Eklund; [2022]
    Nyckelord :Synthetic Control Method; difference-in-differences; synthetic counterfactuals; gross domestic product; European Union; Sweden; common market;

    Sammanfattning : This thesis aims to examine the economic effect in terms of real GDP at constant 2017 national prices (in mil. 2017 US$) of being a member in the European Union in the case of Sweden. The method used to answer the research question is mainly by the Synthetic Control Method. LÄS MER

  5. 5. Predicting Irrational Market Behavior : Examining the Effects of Football Final Outcomes on Index Returns
