  1. 1. Finding Anomalous Energy ConsumersUsing Time Series Clustering in the Swedish Energy Market

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Lukas Tonneman; [2023]
    Nyckelord :time-series analysis; clustering; electricity consumer clustering; anomaly detection; gaussian mixture model; hierarchical clustering;

    Sammanfattning : Improving the energy efficiency of buildings is important for many reasons. There is a large body of data detailing the hourly energy consumption of buildings. This work studies a large data set from the Swedish energy market. LÄS MER

  3. 2. Classification of Radar Emitters using Semi-Supervised Contrastive Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Tim Jonsson; [2023]
    Nyckelord :;

    Sammanfattning : Radar is a commonly used radio equipment in military and civilian settings for discovering and locating foreign objects. In a military context, pilots being discovered by radar could have fatal consequences. LÄS MER

  4. 3. An Intersectional Feminist WAP Pt. 2 : A Unique Case Study of the WAP Music Video by Cardi B and Meg Thee Stallion

    Master-uppsats, Linköpings universitet/Tema Genus

    Författare :Nicola Garoutte; [2023]
    Nyckelord :sexuality; Hip-Hop feminism; HIp-Hop feminist theory; female gaze; intersectionality; intersectional feminism; visual analysis;

    Sammanfattning : Cardi B and Meg Thee Stallion have no problem destroying the male gaze to empower women through the female gaze within the WAP music video. They both empower women by creating a whorehouse for women by women as Cardi B and Meg Thee Stallion both play the role as the entertainer and the entertained therefore forcing the viewer into a trance.

  5. 4. Segmenting cruise passengers based on their spatio-temporal similarity : an approach utilising dynamic time warping

    Kandidat-uppsats, Uppsala universitet/Kulturgeografiska institutionen

    Författare :Pauline Borg; [2023]
    Nyckelord :cruise tourism; dynamic time warping; cluster analysis; overcrowding; tourist mobility; kryssningsturism; dynamic time warping; klusteranalys; trängsel; turistmobilitet;

    Sammanfattning : The present thesis utilises dynamic time warping and cluster analysis with the aim of discovering different touristic profiles. GPS data of cruise passengers intra-destination movement at the destination of Visby, Gotland, was used in the analysis. LÄS MER

  7. 5. Improving Change Point Detection Using Self-Supervised VAEs : A Study on Distance Metrics and Hyperparameters in Time Series Analysis

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Daniel Workinn; [2023]
    Nyckelord :Change point detection; Time series data; Segmentation; Machine learning; Data mining; Detektion av brytpunkter; Tidsseriedata; Segmentering; Maskininlärning; Datautvinning;

    Sammanfattning : This thesis addresses the optimization of the Variational Autoencoder-based Change Point Detection (VAE-CP) approach in time series analysis, a vital component in data-driven decision making. We evaluate the impact of various distance metrics and hyperparameters on the model’s performance using a systematic exploration and robustness testing on diverse real-world datasets. LÄS MER
