  1. 1. Meta-Pseudo Labelled Multi-View 3D Shape Recognition

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

    Författare :Fehmi Ayberk Uçkun; [2023]
    Nyckelord :3D shape recognition; 3D object classification; 3D shape retrieval; 3D object retrieval; Automatic labelling; Semi-supervised learning; Pseudo labelling; Meta Pseudo Labelling; Multi-View Convolutional Neural Networks; Shape descriptors; Multi-view representations; Deeplearning; 3D-formigenkänning; 3D-objektklassificering; 3D-formhämtning; Hämtning av 3D-objekt; Automatisk märkning; Halv-vägledd lärning; Pseudomärkning; Meta Pseudo-märkning; Multi-View Faltningsnät; Formbeskrivningar; Multi-view representation; Djupinlärning;

    Sammanfattning : The field of computer vision has long pursued the challenge of understanding the three-dimensional world. This endeavour is further fuelled by the increasing demand for technologies that rely on accurate perception of the 3D environment such as autonomous driving and augmented reality. LÄS MER

  3. 2. Learning the shapes of protein pockets

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Alejandro Corrochano; Yossra Gharbi; [2022-10-14]
    Nyckelord :Protein; cavity; ligand-binding; 3D-equivariance; shape; latent space; e3nn; Fpocket; sc-PDB;

    Sammanfattning : The comparison of protein pockets plays an important role in drug discovery. Through the identification of binding sites with similar structures, we can assist in finding hits and characterizing the function of proteins. Traditionally, the geometry of cavities has been described with scalar features, which are not fully representative of the shape. LÄS MER

  4. 3. R-ljud är hårda: slumpskogsanalys av sambandet mellan språkljud och betydelse i taktila adjektiv

    Kandidat-uppsats, Stockholms universitet/Statistiska institutionen

    Författare :Emil Råberg; Mia Siljamäki; [2022]
    Nyckelord :random forest; sound symbolism; regression tree; variable importance; permutation importance; slumpskog; random forest; ljudsymbolik; regressionsträd; variable importance;

    Sammanfattning : Få studier om ljudsymbolik, d.v.s. kopplingen mellan ords form och betydelse, har baserats på statistisk analys. LÄS MER

  5. 4. "Are You a Victim for sure?" Media Framing on Sexual Violence and Secondary Victimization in Korea

    Master-uppsats, Lunds universitet/Mänskliga rättigheter

    Författare :Hyokyung Choi; [2022]
    Nyckelord :Sexual violence; power-based sexual violence; victim-survivors; media framing; secondary victimization; #Me; Too; Korea; Social Sciences;

    Sammanfattning : Sexual violence is ubiquitous. It occurs everywhere. Due to the very nature of sex crimes, however, victim-survivors from sexual violence are much more vulnerable from ‘secondary victimization’ which is also known as ‘post crime victimization’ or ‘double victimization. LÄS MER

  7. 5. Temporal Multivariate Distribution Analysis of Cell Shape Descriptors

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Amanda Krantz; [2021]
    Nyckelord :;

    Sammanfattning : In early drug discovery and the study of the effects of new chemical compounds on cancer cells, the change in cell shape over time provides vital information about cell health. Live-cell image analysis systems can be used to extract cell-shape describing parameters of individual cells during exposure to new drugs. LÄS MER
