  1. 1. Regularization Methods and High Dimensional Data: A Comparative Study Based on Frequentist and Bayesian Methods

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Markus Gerholm; Johan Sörstadius; [2024]
    Nyckelord :Linear regression; high dimensional data; regularization; Bayesian methods; Mathematics and Statistics;

    Sammanfattning : As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. LÄS MER

  3. 2. Den historiskt bästa Formel-1 föraren

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Claes Croneborg; Viktor Sjöberg; [2023]
    Nyckelord :Formula One; Multilevel-Model; Beta-Regression; Bayesian Estimation; Monte-Carlo simulation; Markov Chain; Statistics.; Business and Economics; Mathematics and Statistics;

    Sammanfattning : It is difficult to definitively say who the greatest Formula One driver is. It is a subjective assessment and can depend on a variety of factors, including the driver’s skill, their results and accomplishments, their team and car, and the era in which they competed. LÄS MER

  4. 3. Bayesian inference methods for parameter estimation : Implementation and benchmarking

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Sebastian Johansson; [2023]
    Nyckelord :;

    Sammanfattning : In this study, three implementations of the nested sampling algorithm have been implemented, in the programming language Rust, compared and benchmarked. These variations consist of a classic version, closely resembling the first appearance of the algorithm, a version that produces samples from a single ellipsoid, and a version tha tuses multiple ellipsoids to generate its samples.

  5. 4. ESTIMATION OF RADIATION EXPOSURE FROM NATURALLY OCCURRING RADIONUCLIDES IN FOOD AND FOODSTUFF

    Master-uppsats,

    Författare :Ida Bengtsson; [2022-01-13]
    Nyckelord :Medical physics; Naturally occurring radionuclides; committed effective dose from ingested radionuclides; Biokinetic models;

    Sammanfattning : Purpose: The main purpose of this study was to provide an estimation of the committed effective dose received by the Swedish population from naturally occurring radionuclides (NORM) in the diet. This study was also aiming to investigate the impact on the committed effective dose due to the new developments in the biokinetic model for Po 210 . LÄS MER

  7. 5. Non-Bayesian Out-of-Distribution Detection Applied to CNN Architectures for Human Activity Recognition

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Serghei Socolovschi; [2022]
    Nyckelord :Human Activity Recognition; Deep Learning; Time Series; Uncertainty Estimation; Outofdistribution Detection; Convolutional Neural Network; Human Activity Recognition; Deep Learning; Tidsserie; Uppskattning av Osäkerheten; Outofdistribution Detection; Convolutional Neural Network;

    Sammanfattning : Human Activity Recognition (HAR) field studies the application of artificial intelligence methods for the identification of activities performed by people. Many applications of HAR in healthcare and sports require the safety-critical performance of the predictive models. LÄS MER
