  1. 46. 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

  3. 47. AI-assisted analysis of ICT-centre cooling : Using K-means clustering to identify cooling patterns in water-cooled ICT rooms

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Oliver Wallin; Johan Jigsved; [2023]
    Nyckelord :AI; K-means; clustering; ICT-centre; data centre; data center; ICT-center; cooling; data center cooling;

    Sammanfattning : Information and communications technology (ICT) is an important part in today’s society and around 60% of the world's population are connected to the internet. Processing and storing ICT data corresponds to approximately 1% of the global electricity demand. LÄS MER

  4. 48. Clustering and classification of prepaid mortgages

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Jakob Atli Thorsteinsson; [2023]
    Nyckelord :Clustering; Classification; Klustring; Klassificering;

    Sammanfattning : This thesis aims to cluster and classify mortgages issued by a financial institution. The aim is to apply machine learning techniques on historical data in order to discover a possible structure and predictability in prepaid mortgages. LÄS MER

  5. 49. Design and evaluation of a plain MPI-based cluster execution backend for the SkePU 3 skeleton programming framework

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Alexander Zeijlon; [2023]
    Nyckelord :SkePU; skeleton programming; algorithmic skeletons; HPC; cluster; parallel programming; MPI; OpenMP; CUDA; Hybrid; NUMA;

    Sammanfattning : SkePU 3 is a framework for parallel program execution that uses higher order functions called skeletons, which provide a layer of abstraction between user code and the parallel implementation it provides through its backends. The backend that enables SkePU to run on an HPC cluster has a slowdown of a factor two. LÄS MER

  7. 50. Clustering on groups for human tracking with 3D LiDAR

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Simon Utterström; [2023]
    Nyckelord :Computer Vision; Computer Science; AI; Machine Learning; clustering; Kernel Density Clustering; tracking; LiDAR; 3D LiDAR; tracking; human; pedestrian; real time; Datavetenskap; Dataseende; clustering; SLR; CVC; KDEG; KDE; Kernel Density Clustering; HDBSCAN; DBSCAN; LiDAR; point cloud; tracking; human; pedestrian;

    Sammanfattning : 3D LiDAR people detection and tracking applications rely on extracting individual people from the point cloud for reliable tracking. A recurring problem for these applications is under-segmentation caused by people standing close or interacting with each other, which in turn causes the system to lose tracking. LÄS MER
