  1. 1. Exploring Advanced Clustering Techniques for Business Descriptions : A Comparative Study and Analysis of DBSCAN, K-Means, and Hierarchical Clustering

    Uppsats för yrkesexamina på avancerad nivå, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Författare :Wisam Orabi Alkhen; [2023]
    Nyckelord :Machine learning; Business descriptions; Search scope reduction; Relevant business terminology; Data analysis.;

    Sammanfattning : In this study, we introduce several approaches to analyze large volumes of business descriptions by applying machine learning clustering and classification algorithms. The goal is to efficiently classify these descriptions, reducing the search scope and allowing for better business insights and decision-making processes. LÄS MER

  3. 2. A hierarchical neural network approach to learning sensor planning and control

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datorteknik

    Sammanfattning : The ability to search their environment is one of the most fundamental skills for any living creature. Visual search in particular is abundantly common for almost all animals. LÄS MER

  4. 3. Large-scale Exploratory Text Visualisation

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

    Författare :Wilma Axelsson; Nellie Engström; [2023]
    Nyckelord :Natural language processing; information visualisation; text visualisation; Swedish news articles; dynamic topic modeling; hierarchical topic modeling; BERTopic;

    Sammanfattning : The amount of available text data has increased rapidly in the latest years, making it difficult for an everyday user to find relevant information. To solve this, NLP and visualisation methods have been developed for extracting valuable information from text and presenting it to the user. LÄS MER

  5. 4. Autonomous UAV Path Planning using RSS signals in Search and Rescue Operations

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Axel Anhammer; Hugo Lundeberg; [2022]
    Nyckelord :UAV; DQN; Deep Q Network; particle filter; point mass filter; MDP; POMDP; Markov decision process; partially observable Markov decision process;

    Sammanfattning : Unmanned aerial vehicles (UAVs) have emerged as a promising technology in search and rescue operations (SAR). UAVs have the ability to provide more timely localization, thus decreasing the crucial duration of SAR operations. LÄS MER

  7. 5. Assessing Efficiency and Cognitive Load in Form Navigation for Operators in Combat Management Systems

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

    Författare :Omid Mircoram; Niklas André; [2022]
    Nyckelord :;

    Sammanfattning : In naval warfare, warships often need to perform several tasks simultaneously in an unpredictable fast-paced environment. Combat-related tasks are performed by operators in a Naval Combat Management System (NCMS). The challenging environment places high demands on the operators’ ability to work efficiently. LÄS MER
