  1. 1. Anomaly or not Anomaly, that is the Question of Uncertainty : Investigating the relation between model uncertainty and anomalies using a recurrent autoencoder approach to market time series

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Anton Vidmark; [2022]
    Keywords : Uncertainty in deep learning; Bayesian; anomaly detection; novelty detection; stock market; time series;

    Abstract : Knowing when one does not know is crucial in decision making. By estimating uncertainties humans can recognize novelty both by intuition and reason, but most AI systems lack this self-reflective ability. In anomaly detection, a common approach is to train a model to learn the distinction between some notion of normal and some notion of anomalies. READ MORE

  2. 2. CONSTRUCTING AND VARYING DATA MODELS FOR UNSUPERVISED ANOMALY DETECTION ON LOG DATAData modelling and domain knowledge’s impact on anomaly detection and explainability

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Anton Vidmark; [2019]
    Keywords : ;

    Abstract : As the complexity of today’s systems increases, manual system monitoring and log fi€le analysis are no longer applicable, giving an increasing need for automated anomaly detection systems. However, most current research in the domain, tend to focus only on the technical details of the frameworks and the evaluations of the algorithms, and how this impacts anomaly detection results.
