  4. 13. Detecting Fraudulent User Behaviour : A Study of User Behaviour and Machine Learning in Fraud Detection

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analys och partiella differentialekvationer

    Författare :Patrik Gerdelius; Sjönneby Hugo; [2024]
    Nyckelord :Fraud Detection; User Behaviour; Random Forest; PCA; SMOTE;

    Sammanfattning : This study aims to create a Machine Learning model and investigate its performance of detecting fraudulent user behaviour on an e-commerce platform. The user data was analysed to identify and extract critical features distinguishing regular users from fraudulent users. LÄS MER

  5. 14. A Comparative Analysis of Whisper and VoxRex on Swedish Speech Data

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Max Fredriksson; Elise Ramsay Veljanovska; [2024]
    Nyckelord :ASR; Automatic Speech Recognition; Swedish Speech Recognition; Speech Recognition Models; Speech-to-Text; Whisper; VoxRex; Wav2Vec; Model Comparison; Transformer Models; Neural Networks; Machine Learning; WER; Word Error Rate; Transcription;

    Sammanfattning : With the constant development of more advanced speech recognition models, the need to determine which models are better in specific areas and for specific purposes becomes increasingly crucial. Even more so for low-resource languages such as Swedish, dependent on the progress of models for the large international languages. LÄS MER

  7. 15. Predicting Lithium-Ion Battery State of Health using Linear Regression

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Niklas Sundberg; [2024]
    Nyckelord :Lithium-Ion; Multiple Linear Regression; State of Health; Voltage Deviation;

    Sammanfattning : Knowledge of battery health is very important. It provides insight into the capacity of a given system and allows the operators to plan ahead more efficiently. But measuring state of health (SoH) of a battery is difficult, and takes time. More importantly, the battery needs to be taken out of operation to be analysed correctly. LÄS MER
