  1. 1. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Henry Wittler; [2023-11-29]
    Nyckelord :;

    Sammanfattning : Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we investigate by simulation the artifacts on reconstruction when noise are present in the measurement. 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. Förutsäga spelresultat i Dota 2 med NLP och maskininlärningsalgoritmer

    Master-uppsats, Jönköping University/JTH, Avdelningen för datateknik och informatik

    Författare :Bálint Sándor; Ziping Wan; [2023]
    Nyckelord :;

    Sammanfattning : Esports has grown quickly in recent years, and the business has produced a ton of specifications-based data that is simple to obtain. Because of the aforementioned traits, data mining and deep learning techniques can be used to direct participants and create winning strategies. LÄS MER

  5. 4. Investigations of Free Text Indexing Using NLP : Comparisons of Search Algorithms and Models in Apache Solr

    Master-uppsats, Linköpings universitet/Interaktiva och kognitiva system

    Författare :Alfred Sundstedt; [2023]
    Nyckelord :NLP; Apache Solr; Document Retrieval; Context; OpenNLP; BERT;

    Sammanfattning : As Natural Language Processing progresses societal and applications like OpenAI obtain more considerable popularity in society, businesses encourage the integration of NLP into their systems. Both to improve the user experience and provide users with their requested information. LÄS MER

  7. 5. A Comparison Between Implementations of Cryptographic Algorithms and Their Efficiency in Smartphone Computing Environments : Exploring the Performance Trade-offs of Performing Cryptographic Work in Different Smartphone Development Frameworks

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

    Författare :Ossian Dillner; [2023]
    Nyckelord :Cryptography; Security; Privacy; Smartphones; Kryptografi; Säkerhet; Integritet; Smartphones;

    Sammanfattning : In the recent decade concern for privacy has massively increased in the public consciousness. As a result of this development, demand for end-to-end secure communications in all manner of applications has also seen a rapid increase. This development can however often be at odds with other consumer demands. LÄS MER
