  1. 6. Regression and time estimation in the manufacturing industry

    University essay from Uppsala universitet/Statistik, AI och data science

    Author : Walter Bjernulf; [2023]
    Keywords : regression; linear regression; regression trees; random forests; cross validation; variable selection; conformal prediction;

    Abstract : In this thesis an analysis is performed on operation times for different sized products in a manufacturing company. The thesis will introduce and summarise most of the theory needed to perform regression and also cover a worked example where three different regression models are learned, evaluated and analysed.

  3. 7. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications

    University essay from KTH/Teknisk mekanik

    Author : Simon Garpenquist; [2023]
    Keywords : Wind Tunnel Experiment; Computational Fluid Dynamics; Aerodynamic Forces; Drag Reduction; Shape Optimization; Flow around Cylinders; Yacht Racing;

    Abstract : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. READ MORE

  4. 8. Predicting heart failure emergency readmissions

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Paromita Sur; Alexander Stenberg; [2023]
    Keywords : Machine Learning; Patient readmission; Heart Failure; Electronic Health Records;

    Abstract : Recent progress in treatment interventions has resulted in increased survival rates and longevity for diagnosed heart failure patients. However, heart failure still remains one of the leading causes of rehospitalization worldwide, where emergency readmissions continue to be a common occurrence. READ MORE

  5. 9. A Predictive Analysis of Customer Churn

    University essay from KTH/Matematisk statistik

    Author : Olivia Eskils; Anna Backman; [2023]
    Keywords : Churn prediction; CRM; optimization; applied mathematics; machine learning; gradient boosting; random forest; logistic regression; insurance industry; Kundbortfall; CRM; optimering; tillämpad matematik; maskininlärning; gradient boosting; random forest; logistisk regression; försäkringsbranschen;

    Abstract : Churn refers to the discontinuation of a contract; consequently, customer churn occurs when existing customers stop being customers. Predicting customer churn is a challenging task in customer retention, but with the advancements made in the field of artificial intelligence and machine learning, the feasibility to predict customer churn has increased.

  6. 10. Robustness Against Non-Normality : Evaluating LDA and QDA in Simulated Settings Using Multivariate Non-Normal Distributions

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Gånheim Viktor; Åslund Isak; [2023]
    Keywords : Classification; Linear Discriminant Analysis; Quadratic Discriminant Analysis; Normality Assumption;

    Abstract : Evaluating classifiers in controlled settings is essential for empirical applications, as extensive knowledge on model-behaviour is needed for accurate predictions. This thesis investigates robustness against non-normality of two prominent classifiers, LDA and QDA. READ MORE
