1. 1. 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

   Sammanfattning : Vector Quantization (VQ) is a classic optimization problem and a simple approach to pattern recognition. Applications include lossy data compression, clustering and speech and speaker recognition. LÄS MER

4. 3. Spatio-temporal outlier detection in streaming trajectory data

   Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

   Författare :MÁTÉ SZEKÉR; [2014]
   Nyckelord :;

   Sammanfattning : This thesis investigates the problem of detecting spatiotemporalanomalies in streamed trajectory data using both supervised and unsupervised algorithms. Anomaly detection can be understood as an unsupervised classification problem which requires the knowledge of the normal course of events or how the anomalies manifest themselves. LÄS MER
