    Keywords : Networks; Interactive Visualizations; Insurance Cases; Data; Analytics; Business and Economics;

    Abstract : Companies are seeking new ways to analyse data, and network visualizations are a great tool to enhance the ability to understand relational data. The objective of this thesis project was to build an interactive network visualization of an insurance company’s portfolio. READ MORE

  4. 33. Analysis of Electricity Usage Time Series with K-means Clustering

    University essay from Uppsala universitet/Elektricitetslära

    Author : Göran Iliev; [2022]
    Keywords : electricty usage; office; residential; time series; clustering;

    Abstract : As the amount of collected and analysed data for electricity usage from buildings is increasing it becomes an important component in energy efficiency efforts. A huge problem when developing algorithms fordetection of anomalous electricity usage series is the lack of data setswith annotated normal usage series for training and evaluation purposes.
