  1. 1. A Gradient Boosting Tree Approach for Behavioural Credit Scoring

    University essay from KTH/Matematisk statistik

    Author : Axel Dernsjö; Ebba Blom; [2023]
    Keywords : Machine learning; Random forest; Uncertainty measure; Material development; Empirical Bayes; Maskininlärning; Random forest; Osäkerhetsmått; Materialutveckling; Empirical Bayes;

    Abstract : This report evaluates the possibility of using sequential learning in a material development setting to help predict material properties and speed up the development of new materials. To do this a Random forest model was built incorporating carefully calibrated prediction uncertainty estimates. READ MORE

  3. 3. Bayes Factors for the Proposition of a Common Source of Amphetamine Seizures.

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Yash Pawar; [2021]
    Keywords : Amphetamine Data; LDA; PLS-DA; NSC; Gaussaianize; pairwise ratios;

    Abstract : This thesis sets out to address the challenges with the comparison of Amphetamine material in determining whether they originate from the same source or different sources using pairwise ratios of peak areas within each chromatogram of material and then modeling the difference between the ratios for each comparison as a basis for evaluation. The evaluation of an existing method that uses these ratios to determine the sum of significant differences between each comparison of material that is provided is done. READ MORE

  4. 4. Implementation of SLAM Algorithms in a Small-Scale Vehicle Using Model-Based Development

    University essay from Linköpings universitet/Datorteknik

    Author : Johan Alexandersson; Olle Nordin; [2017]
    Keywords : SLAM; Robotics; Particle Filter; Bayes; Kalman Filter. Navigation; Localization; Mapping; ROS; Model-based development; SLAM; Robotik; Partikelfilter; Bayes; Kalmanfilter; Navigering; Lokalisering; Kartläggning; ROS; Modellbaserad utveckling;

    Abstract : As autonomous driving is rapidly becoming the next major challenge in the auto- motive industry, the problem of Simultaneous Localization And Mapping (SLAM) has never been more relevant than it is today. This thesis presents the idea of examining SLAM algorithms by implementing such an algorithm on a radio con- trolled car which has been fitted with sensors and microcontrollers. READ MORE

  5. 5. Responding to the Eurozone Crisis - Applying the Shadow Rating Approach to Determine Economic Capital for Sovereign Exposures

    University essay from Lunds universitet/Matematisk statistik

    Author : Simon Koskinen Rosemarin; [2014]
    Keywords : Mathematics and Statistics;

    Abstract : The recent European sovereign-debt crisis has made it clear that exposures towards sovereigns contain credit risk. However, according to the Basel framework's standardized approach banks are not required to hold any regulatory capital for highly rated sovereigns. READ MORE
