  1. 6. Domain Knowledge and Representation Learning for Centroid Initialization in Text Clustering with k-Means : An exploratory study

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

    Författare :David Yu; [2023]
    Nyckelord :Natural language processing; Sentiment analysis; Clustering; Language model; Transformer; Heuristic; Språkteknologi; Sentimentanalys; Klustering; Språkmodell; Transformer; Heuristik;

    Sammanfattning : Text clustering is a problem where texts are partitioned into homogeneous clusters, such as partitioning them based on their sentiment value. Two techniques to address the problem are representation learning, in particular language representation models, and clustering algorithms. LÄS MER

  3. 7. Challenges in the Maintenance and Diagnostic Segment of Digital Asset Management in the Swedish Railway Industry

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Salam Adeeb; Marwan Ouali; [2023]
    Nyckelord :Railway Digital Asset Management; remote monitoring; condition-based maintenance; predictive maintenance; Digital tillgångsförvaltning; prediktivt underhåll; tillståndsbaserat underhåll; diagnostik;

    Sammanfattning : Just like the rest of society, the use of digital technology has throughout the years become a more crucial part for train companies to improve performance, meet customer demands, improve operation and maintenance processes to increase efficiency and reliability. These solutions have through time developed to become part of a cluster named Digital Asset Management (DAM). LÄS MER

  4. 8. Geographic polarization and clustering of partisan voting: A local-level analysis of Stockholm Municipality

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Jonas Almén; [2023]
    Nyckelord :Geography; GIS; Spatial Analysis; Spatial Autocorrelation; MAUP; Electoral Geography; Political Polarization; Geographic Polarization; Stockholm Municipality; Earth and Environmental Sciences;

    Sammanfattning : In the last decade, the topic of political polarization has become a growing concern within academic and public debate. Many highlight the linkage between increased political polarization and democratic problems such as political tribalism and uncivil activism. It is also argued to be a global phenomenon. LÄS MER

  5. 9. Unsupervised Clustering of Behavior Data From a Parking Application : A Heuristic and Deep Learning Approach

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Edvard Magnell; Joakim Nordling; [2023]
    Nyckelord :ML; Machine learning; clustering; unsupervised learning; deep learning; autoencoder; AI; artificial intelligence;

    Sammanfattning : This report aims to present a project in the field of unsupervised clustering on human behavior in a parking application. With increasing opportunities to collect and store data, the demands to utilize the data in meaningful ways also increase. LÄS MER

  7. 10. Exogenous Fault Detection in Aerial Swarms of UAVs
