  1. 1. The State of Live Facial Puppetry in Online Entertainment

    Magister-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Lisa Gren; Denny Lindberg; [2024]
    Nyckelord :Facial Puppetry; Face Tracking; Real-time Rendering; Motion Capture; Computer Vision; 3D Modeling; Virtual Avatars; Augmented Reality; Machine Learning; Game Development;

    Sammanfattning : Avatars are used more and more in online communication, in both games and socialmedia. At the same time technology for facial puppetry, where expressions of the user aretransferred to the avatar, has developed rapidly. LÄS MER

  3. 2. An Empirical Survey of Bandits in an Industrial Recommender System Setting

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

    Författare :Tobias Schwarz; Johan Brandby; [2023-09-21]
    Nyckelord :computer science; industrial application; machine learning; reinforcement learning; multi-armed bandits; MAB; contextual multi-armed bandits; survey; batch learning;

    Sammanfattning : In this thesis, the effects of incorporating unstructured data—images in the wild—in contextual multi-armed bandits are investigated, when used within a recommender system setting, which focuses on picture-based content suggestion. The idea is to employ image features, extracted by a pre-trained convolutional neural network, and study the resulting bandit behaviors when including respective excluding this information in the typical context creation, which normally relies on structured data sources—such as metadata.

  4. 3. Tools evolving AI systems via experiment management: A survey of machine learning practitioners

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

    Författare :Carl Vågfelt Nihlmar; [2023-04-28]
    Nyckelord :experiment management tools; machine learning; experiment management; experiment tracking; artificial intelligence;

    Sammanfattning : Artificial intelligence employs machine learning to create intelligent systems. Experiment management tools have been created to support machine learning practitioners in their development efforts relating to the management of artifacts and metadata. LÄS MER

  5. 4. Unsupervised Online Anomaly Detection in Multivariate Time-Series

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datorteknik

    Författare :Ludvig Segerholm; [2023]
    Nyckelord :unsupervised; online; anomaly detection; explainable ai; machine learning; mahalanobis distance;

    Sammanfattning : This research aims to identify a method for unsupervised online anomaly detection in multivariate time series in dynamic systems in general and on the case study of Devwards IoT-system in particular. A requirement of the solution is its explainability, online learning and low computational expense. LÄS MER

  7. 5. Analyzing Toxicity in YouTube Comments with the Help of Machine Learning

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Sasan Dehkhoda; Jasmyn Ali Gunica; [2023]
    Nyckelord :Toxic comments; YouTube; Machine Learning; Natural Language Processing;

    Sammanfattning : Toxic comments are overall likely to make someone feel uncomfortable and leave a discussion and are therefore potentially problematic. Toxic comments occur online on various social media, and depending on the site, get detected manually or via machine learning algorithms (or both), and removed depending on the severity and other factors.
