  1. 1. SubKluster: Novel method to bin scaffolds from cereal genomes into subgenomes using substring frequency analysis

    University essay from Lunds universitet/Examensarbeten i bioinformatik

    Author : Victor Kalbskopf; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : The genome of the Belinda variety of the hexaploid oat (Avena sativa) has recently been sequenced and assembled. This project aims to improve the assembly by clustering the thousands of scaffolds into their three ancestral subgenomes using Principle Component Analysis (PCA) of kmer and repeat-element frequencies.

  3. 2. Czekanowski’s Clustering : Development of Visualization Possibilities of the RMaCzek Package

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Ying Luo; [2022]
    Keywords : Cluster Analysis; Graph Visualization; Czekanowski’s Diagram; Seriation Methods; Changing Points Detection;

    Abstract : As one of the most essential data mining tasks, clustering analysis has been widely discussed and employed since its invention. Czekanowski’s diagram, which has been around for over a century as a visualization tool for exploring cluster distributions, is being improved continually. READ MORE

  4. 3. Community Detection in Directed Graphs for Cell-to-Sector Mapping Using Handover Statistics in Mobile Communication Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Rommedahl; [2022]
    Keywords : Community detection; Communications networks; Handover; Sectors; Directed graphs; Binary classification; Graph clustering; Gemenskapsdetektion; Kommunikationsnätverk; Handover; Sektorer; Riktade grafer; Binär klassification; Grafklustring;

    Abstract : Many use cases in mobile communication networks are dependent on knowledge of which cells serve the same sector. These use cases include network planning, optimization and troubleshooting. Current methods of obtaining knowledge regarding this cell-to-sector mapping are based on naming conventions of cells.

  5. 4. Discover patterns within train log data using unsupervised learning and network analysis

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Zehua Guo; [2022]
    Keywords : Log analysis; Natural language processing; Unsupervised learning; Clustering; Network analysis; Logganalys; Bearbetning av naturligt språk; Oövervakat lärande; Clustering; Nätverksanalys;

    Abstract : With the development of information technology in recent years, log analysis has gradually become a hot research topic. However, manual log analysis requires specialized knowledge and is a time-consuming task. Therefore, more and more researchers are searching for ways to automate log analysis. READ MORE

  6. 5. Properties of Discrete Laplacians With Application on Brain Networks

    University essay from KTH/Matematisk statistik

    Author : David Thinsz; [2022]
    Keywords : Graph Laplacian; Combinatorial Laplacian; Persistent Laplacian; Topological data analysis; Spectral theory; Homology; Clustering.; Graf-Laplacian; Kombinatorisk Laplacian; Beständig Laplacian; Topologisk dataanalys; Spektralteori; Homologi; Klustring.;

    Abstract : This thesis investigates three discrete Laplace operators: the graph Laplacian, combinatorial Laplacian, and the more recently introduced persistent Laplacian. We discuss how these operators relate to each other and study their spectral properties. The graph Laplacian is a well-studied operator that plays a central role in spectral graph theory. READ MORE
