  1. 1. Audio Anomaly Detection in Cars

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Asma Hussein; [2023-09-11]
    Nyckelord :Audio Anomaly detection; Outlier detection; Machine learning; Mel Frequency; Chroma;

    Sammanfattning : Audio anomaly detection in the context of car driving is a crucial task for ensuring vehicle safety and identifying potential faults. This paper aims to investigate and compare different methods for unsupervised audio anomaly detection using a data set consisting of recorded audio data from fault injections and normal "no fault" driving.

  4. 3. Anomaly detection on factory lathe using audio analysis and deep learning

    Magister-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Gabriel Berthold; Jonas Kinnvall; [2019]
    Nyckelord :;

    Sammanfattning : This paper presents a master’s thesis project in which a system for anomaly detection on sound of a factory lathe has been developed and evaluated. The audio has been recorded with a microphone on site and has been analyzed using Fourier transforms and a Gated Recurrent Unit, developed to detect when this machine is running. LÄS MER
