  1. 11. An exploration of topological properties of high-frequency one-dimensional financial time series data using TDA

    Master-uppsats, KTH/Matematisk statistik

    Författare :Patrick Truong; [2017]
    Nyckelord :;

    Sammanfattning : Topological data analysis has been shown to provide novel insight in many natural sciences. To our knowledge, the area is however relatively unstudied on financial data. This thesis explores the use of topological data analysis on one dimensional financial time series. LÄS MER

  3. 12. Illustrations of Data Analysis Using the Mapper Algorithm and Persistent Homology

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Rami Kraft; [2016]
    Nyckelord :;

    Sammanfattning : The Mapper algorithm and persistent homology are topological data analysis tools used for analyzing point cloud data. In addition a classification method is used as a part of the data analysis toolchain adopted in this thesis in order to serve as a distinguishing technique for two class labels. LÄS MER

  4. 13. Algorithms for Multidimensional Persistence

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Oliver Gäfvert; [2016]
    Nyckelord :Multidimensional persistence; persistent homology; topological data analy-sis; invariants; barcode; algorithms.; Multidimensionell persistens; persistent homologi; topologisk data-analys; invarianter; streckkod; algoritmer;

    Sammanfattning : The theory of multidimensional persistence was introduced in a paper by G. Carlsson and A. Zomorodian as an extension to persistent homology. The central object in multidimensional persistence is the persistence module, which represents the homology of a multi filtered space. LÄS MER

  5. 14. A topological approach to data visualization

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Henrik Löfberg; [2015]
    Nyckelord :;

    Sammanfattning : Barcoding is a mathematical tool, to analyze data, which is based on the theory of persistent homology. In this thesis both Hierarchical Clustering and Barcoding are defined and analyzed according to three criterion: Continuity, Computability and Visualizability. LÄS MER

  7. 15. Molecular studies on infections with two nidoviruses: Bovine Coronavirus and Equine Arteritis Virus

    L3-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Lihong Liu; [2004]
    Nyckelord :equine arteritis virus; genetic variation; open reading frame; RT-PCR;

    Sammanfattning : Infections with nidoviruses can cause various problems in animals and human beings. Bovine coronavirus (BCoV) has been considered as an important pathogen, causing severe diarrhea of newborn calves, winter dysentery of adult cattle, and respiratory disease in calves. LÄS MER
