  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. Digital Front End Algorithms for Sub-Band Full Duplex

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

    Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

  4. 3. Anomaly Detection for Network Traffic in a Resource Constrained Environment

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Pontus Lidholm; Gaia Ingletto; [2023]
    Keywords : Network Traffic; Anomaly Detection; Embedded Systems; Machine Learning; Random Forest;

    Abstract : Networks connected to the internet are under a constant threat of attacks. To protect against such threats, new techniques utilising already connected hardware have in this thesis been proven to be a viable solution. READ MORE

  5. 4. 'This Game Changed my Life' : Online Stories of ‘Emersion’ about Playing Video Games during Difficult Times in Life

    University essay from Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Author : Sergio J. Abuin; [2023]
    Keywords : video games; videogames; personal crises; difficult times; immersion; netnography; stories; posts; online; offline; uses and gratifications; Reddit; Persona 5; videojocs; video jocs; temps dificils; immersió; historia; videojuegos; video juegos; crisis; tiempos difíciles; inmersión; netnografia; historias;

    Abstract : This thesis aims to explore the video game medium in depth, to relate it to the stories foundon Internet communities about users’ gameplay experiences during burdensome moments inlife. To achieve that, the phenomena is explored through the lenses of Uses & Gratificationstheory by means of a netnography on the ‘/Persona 5’ official subReddit; interpreting, codingand analyzing all narratives that fit the criteria with the help of a proposed ‘USE’ system.

  6. 5. Measurements, Estimations and Calibration with a Fully Digital Array

    University essay from Uppsala universitet/Signaler och system

    Author : Oscar Magnér; [2023]
    Keywords : WiDAR; signal processing; digital array; broadband antenna; array antenna; antenna; calibration; direct sampling; antenn; bredbandig; digital array; array antenn; direktsampling; signalbehandling; kalibrering; WiDAR; Saab AB; SAAB;

    Abstract : In modern digital communication, transmission and reception of information through electromagnetic signals requires digital devices that can process high data rates accurately despite being located in information heavy environments. One type of antenna receiver is the digital antenna array, which can steer its lobes electronically to increase or decrease sensitivity in specific directions. READ MORE
