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

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

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

    Abstract : 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.

  3. 2. Detecting inconsistencies of safety artifacts with Natural Language Processing Bachelor of Science Thesis

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Xuni Huang; [2023-01-09]
    Keywords : Inconsistencies; Safety-critical systems; Natural language processing; Classification;

    Abstract : This paper investigates a method that helps detect inconsistencies between safety-critical systems’ textual safety artifacts that safety cases rely on by involving NLP techniques. A design science research study was conducted in three iterations. I evaluate the method by conducting different experiments. READ MORE

  4. 3. Randomized Diagonal Estimation

    University essay from KTH/Matematik (Avd.)

    Author : Niclas Joshua Popp; [2023]
    Keywords : Diagonal estimation; randomized numerical linear algebra; low-rank approximation; matrix functions; Diagonalestimering; randomiserad numerisk linjär algebra; lågrankad approximation; matrisfunktioner;

    Abstract : Implicit diagonal estimation is a long-standing problem that is concerned with approximating the diagonal of a matrix that can only be accessed through matrix-vector products. It is of interest in various fields of application, such as network science, material science and machine learning. READ MORE

  5. 4. Enhancing path following drone : using image-based sensor matrix

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Lakshmi Sai Krishna Yarru; Timothy Frazer Penugonda; [2023]
    Keywords : drone;

    Abstract : Drones are a fascinating form of transport and have the potential to dominate transportation in the future. Drones are usually faster and are unstable when flying in the air. Drones can be automated in many ways to realize various applications, one of which is a path following drone. READ MORE

  6. 5. CFD-modeling of labyrinth weir flood discharge with ice cover

    University essay from KTH/Betongbyggnad

    Author : Erik Isberg; [2023]
    Keywords : ;

    Abstract : A labyrinth weir is a hydraulic structure built with a purpose to increase the discharge capacity compared to linear weirs, while maintaining the same water level upstream. Construction of labyrinth weirs is vital in a future with more unpredictable flows. READ MORE
