3. 2. Predicting True Sepsis and Culture-positive Sepsis in Intensive Care Unit with Machine Learning Techniques

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Zeyuan Wu; [2024]
   Nyckelord :Machine Learning; Diagnosis of Sepsis; XGBoost; Logistic Regression; Mathematics and Statistics;

   Sammanfattning : Sepsis, a serious medical condition often leading to patients requiring intensive care, has prompted numerous scientists to employ mathematical techniques to aid in its diagnosis. This thesis uses logistic regression and a machine learning technique, XGBoost, to predict true sepsis (as opposed to sepsis mimics) and culture-positive sepsis (among true sepsis) in critical care using blood test results, physiological measurements and other patient characteristics.

4. 3. Using NeRF- and Mesh-Based Methods to Improve Visualisation of Point Clouds

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Vilma Ylvén; Oscar Montelin; [2024]
   Nyckelord :Technology and Engineering; Mathematics and Statistics;

   Sammanfattning : In recent years, the field of generating synthetic images from novel view points has seen some major improvements. Most importantly with the publication of Neural Radiance Fields allowing for extremely detailed and accurate 3D novel views. LÄS MER

5. 4. The Effects of Social Assistance and Unemployment Insurance on Employment Outcomes : Evidence from new micro level administrative data at Statistics Sweden

   Master-uppsats, Uppsala universitet/Nationalekonomiska institutionen

   Författare :Molly Bernhardsson; [2024]
   Nyckelord :Social assistance; Unemployment insurance; Employment outcomes; Propensity score matching; Kaplan-Meier estimator;

   Sammanfattning : In this study, I examine the employment effects on average earnings and duration to work during a 45 month period, after receiving social assistance (SA) in October 2019, compared to receiving unemployment insurance (UI) the same month. A distinction is made between two treatment groups; receiving SA in addition to UI (treatment I) and receiving SA (treatment II). LÄS MER

7. 5. A temporal Hawkes process model for shooting occurrences in Sweden

   Kandidat-uppsats, Lunds universitet/Statistiska institutionen

   Författare :Sara Kopelman; [2024]
   Nyckelord :Point processes; stochastic processes; statistics; conditional intensity; crime; shootings; Mathematics and Statistics;

   Sammanfattning : The Hawkes process, also referred to as a self-exciting point process, is a class of point processes where the intensity is conditioned on previous events. More specifically, an event occurrence excites the process, temporarily increasing the probability of more events occurring. LÄS MER
