  1. 11. Using Gradient Boosting to Identify Pricing Errors in GLM-Based Tariffs for Non-life Insurance

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Felix Greberg; Andreas Rylander; [2022]
    Nyckelord :GLM; Gradient Boosting; XGBoost; Non-life insurance; Property Casualty; Rate making; Insurance Tariff; MTPL insurance; Machine learning; Regression trees; Tweedie regression; Credit risk; GLM; Gradient Boosting; XGBoost; Skadeförsäkring; Prissättning; Försäkringstariff; Trafikförsäkring; Regressionsträd; Maskininlärning; Tweedie-regression; Kreditrisk;

    Sammanfattning : Most non-life insurers and many creditors use regressions, more specifically Generalized Linear Models (GLM), to price their liabilities. One limitation with GLMs is that interactions between predictors are handled manually, which makes finding interactions a tedious and time-consuming task. LÄS MER

  3. 12. Spridningsfaktorer av invasiva arter inom C-verksamheter

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Isabella Winberg; [2022]
    Nyckelord :;

    Sammanfattning : Den tilltagande höga nivån av urbanisering och vägbyggen är en bidragande faktor till spridning av invasiva arter. Transporter och frekventa vegetationsstörningar resulterar i homogena, öppna och soliga landskap med minskad konkurrens där snabbt växande ruderala arter med hög ihållande fröproduktion etablerar sig, varav många är invasiva.

  5. 14. Data-driven asthma phenotypes fail to accommodate personalized follow-up strategies in primary care

    Master-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Carolin Wingefors; [2022]
    Nyckelord :asthma phenotypes; cluster analysis; asthma control; exacerbations; follow-up.;

    Sammanfattning : Introduction Asthma is a common and heterogeneous disease in primary care. Asthma phenotypes are recognisable clusters of for example clinical characteristics. Current asthma symptoms and previous exacerbations are used to assess the level of asthma control. Asthma control is used clinically to plan follow-up strategies. LÄS MER

  7. 15. Measures of statistical dependence for feature selection : Computational study

    Magister-uppsats, Umeå universitet/Statistik

    Författare :Mohamad Alshalabi; [2022]
    Nyckelord :;

    Sammanfattning : The importance of feature selection for statistical and machine learning models derives from their explainability and the ability to explore new relationships, leading to new discoveries. Straightforward feature selection methods measure the dependencies between the potential features and the response variable. LÄS MER
