  5. 9. The Demos Index

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Axel Simonsson; [2023]
    Nyckelord :Demos; Boundary Problem; Democracy Evaluation; Nationalist Principle; All-Affected Principle; Coercion Principle; Mixed Methods; Democracy Index; Demos Index; Law and Political Science;

    Sammanfattning : Democracy is both a question of who the people are (demos) and how they rule (kratos); our understanding of democracy is imbalanced in favour of the latter. The aim of this thesis is to conduct a pilot project evaluating and comparing the level of democracy from a demos perspective through an index. LÄS MER

  7. 10. Multi-Class Classification for Predicting Customer Satisfaction : Application of machine learning methods to predict customer satisfaction at IKEA

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Stina Backerholm; Malin Börjesjö; [2023]
    Nyckelord :Multi-Class Classification; Imbalanced Data; Machine Learning; Multi-Klass Klassifisering; Obalanserat Data; Maskininlärning;

    Sammanfattning : Gaining a comprehensive understanding of the features that contribute to customer satisfaction after contact with IKEA’s Remote Customer Meeting Points (RCMPs) is essential for implementing effective remedial measures in the future. The aim of this project is to investigate if it is possible to find key features that influence customer satisfaction and to use these to predict customer satisfaction. LÄS MER
