  1. 1. Variable selection techniques for the Cox proportional hazardsmodel: A comparative study

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Simon Peterson; Klas Sehlstedt; [2018-03-08]
    Nyckelord :All subset selection; Backward elimination; Best subset selection; BeSS; Cox proportinal hazards model; least absolute shrinkage and selction operator; LASSO;

    Sammanfattning : In statistics different models are used to emulate real world processes. Variable selection refers to reduction of the number of parameters in the models in order to increase interpretability and model effectiveness. LÄS MER

  2. 2. TOPIC MODELING FOR ANALYSIS OF PUBLIC DISCOURSE -Enriching topic modeling with linguistic information to analyze Swedish housing policies

    Master-uppsats, Göteborgs universitet/Institutionen för filosofi, lingvistikoch vetenskapsteori

    Författare :Anna Lindahl; [2018-01-15]
    Nyckelord :topic modeling; public discourse; housing policies; LDA; semantic coherence measures; part of speech;

    Sammanfattning : This work investigates how the method of topic modeling can be applied to investigate the public discourse of Swedish housing policies. The data used to represent this discourse is both from the Swedishparliament, the Riksdag, and Swedish newstexts. The lack of housing and current housing crisis in Swedenmakes this a relevant area to study. LÄS MER

  3. 3. eulerr: Area-Proportional Euler Diagrams with Ellipses

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Johan Larsson; [2018]
    Nyckelord :Euler diagrams; Venn diagrams; ellipses; R; computer graphics; area-proportional; software; Mathematics and Statistics;

    Sammanfattning : Euler diagrams are common and intuitive visualizations for data involving sets and relationships thereof. Compared to Venn diagrams, Euler diagrams do not require all set relationships to be present and may therefore be area-proportional also with subset or disjoint relationships in the input. LÄS MER

  4. 4. Millimeter Wave Antenna Array Calibration and Validation for 5G New Radio Access

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Manuel Jose Lopez Morales; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This Master thesis work was performed in Ericsson AB, Lund. It studies and validates two classes of algorithms to be used in mm-wave massive MIMO antenna arrays, for their use in the future 5G mobile communication systems. LÄS MER

  5. 5. Pattern Recognition applied to Continuous integration system.

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Författare :SHIVAKANTHREDDY VANGALA; [2018]
    Nyckelord :continuous integration; pattern recognition; artificial neural network; k-nearest neighbors;

    Sammanfattning : Context: Thisthesis focuses on regression testing in the continuous integration environment which is integration testing that ensures that changes made in the new development code to thesoftware product do not introduce new faults to the software product. Continuous integration is software development practice which integrates all development, testing, and deployment activities. LÄS MER
