  3. 17. Multivariate analysis and classification of pathogenic priming components in wild-type and lab mice

    Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Armand Stoe; [2023]
    Nyckelord :;

    Sammanfattning : Animal models have a long history of being used in research for the purpose of investigating biological processes and testing the effect of specific compounds on the functionality of biological processes. Different types of mice are used as animal models, most notably inbred and outbred strains. LÄS MER

  4. 18. Evaluating clustering techniques in financial time series

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Johan Millberg; [2023]
    Nyckelord :clustering; machine learning; financial time series; time series; unsupervised learning; cluster validation; cluster evaluation; klustring; klusteranalys; finansiella tidsserier; maskininlärning; klustervalidering; evalueringsteknik;

    Sammanfattning : This degree project aims to investigate different evaluation strategies for clustering methodsused to cluster multivariate financial time series. Clustering is a type of data mining techniquewith the purpose of partitioning a data set based on similarity to data points in the same cluster,and dissimilarity to data points in other clusters.

  5. 19. An Open-Source Autoencoder Compression Tool for High Energy Physics

    Magister-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Axel Gallén; [2023]
    Nyckelord :Physics; Particle Physics; Analysis; Machine Learning; Neural Networks; Autoencoders; Data Compression; Lossy Compression; Baler; Physics and Astronomy;

    Sammanfattning : A common problem across scientific fields and industries is data storage. This thesis presents an open-source lossy data compression tool with its foundation in Machine Learning - Baler. Baler has been used to compress High Energy Physics (HEP) data, and initial compression tests on Computational Fluid Dynamics (CFD) toy data have been performed. LÄS MER

  7. 20. Capturing time variation within systemic risk estimation

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Christian Hovstadius; Baltsar Lindgren; [2023]
    Nyckelord :Systemic risk; CoVaR; State variables; Lasso; PCA; Business and Economics;

    Sammanfattning : Systemic risk can be defined as the risk to the whole financial system. Financial institutions may contribute more or less to this risk, and measuring the systemic risk contributions of institutions is of central importance for regulators. LÄS MER
