  1. 1. Abnormality detection in diagnostics data from network cameras

    University essay from Lunds universitet/Matematik LTH

    Author : André Hedesand; Oliver Dageson; [2021]
    Keywords : machine learning; change detection; anomaly detection; data synthesis; forecasting; gradient boost; Mathematics and Statistics;

    Abstract : For data-driven companies, there is a need to efficiently navigate through big quantities of collected data. In our case; detecting changes in the behaviour of data. We have investigated whether machine learning could be applied to automate the process of finding abnormal behaviour (anomalies) in collected data. READ MORE

  3. 2. Estimation of Ship Properties for Energy Efficient Automation

    University essay from Linköpings universitet/Reglerteknik

    Author : Lucas Nilsson; [2016]
    Keywords : System identification; ship properties; energy efficient; automation; ship modelling; estimation; signal processing; simulation; ship dynamics; cusum; cumulative summation; change in dynamics; load condition; podded propulsion; azipod; yaw dynamics; noise impact; measurement noise; model error; bias due to model error; ship yaw model; moment of inertia; estimate ship properties; ship automation;

    Abstract : One method to increase efficiency, robustness and accuracy of automatic control, is to introduce mathematical models of the system in question to increase performance. With these models, it is possible to predict the behavior of the system, which enables control according to the predictions. READ MORE

  4. 3. Locating Multiple Change-Points Using a Combination of Methods

    University essay from KTH/Matematisk statistik

    Author : Johan Andersson; [2014]
    Keywords : ;

    Abstract : The aim of this study is to find a method that is able to locate multiple change-points in a time series with unknown properties. The methods that are investigated are the CUSUM and CUSUM of squares test, the CUSUM test with OLS residuals, the Mann-Whitney test and Quandt’s log likelihood ratio. READ MORE
