  1. 21. A Physics-Informed Deep Learning Framework for Solving Inverse Problems in Epidemiology

    University essay from KTH/Optimeringslära och systemteori

    Author : Magnus Tronstad; [2022]
    Keywords : ;

    Abstract : This thesis develops and evaluates a physics-informed neural network (PINN) modelling framework for solving inverse problems in epidemiology. The PINN works by modifying the standard mean squared error loss function of the neural network, by adding a term penalizing deviations from a given compartmental model's system of ordinary differential equations.

  3. 22. The Inverse Source Problem for Helmholtz

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Hugo Fernstrom; Hugo Sträng; [2022]
    Keywords : inverse problem; inverse source problem; Helmholtz; Tikhonov regularization;

    Abstract : This paper studies the inverse source problem for the Helmholtz equation with a point source in a two dimensional domain. Given complete boundary data and appropriate discretization Tikhonov regularization is established to be an effective method at finding the point source. READ MORE

  4. 23. Parameter estimation in a cardiovascular computational model using numerical optimization : Patient simulation, searching for a digital twin

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Giulia Tuccio; [2022]
    Keywords : Parameter estimation; Enhanced Scatter Search; Particle Swarm; Hooke and Jeeves; Cardiovascular Models; Parameteruppskattning; förbättrad spridningssökning; Particle Swarm; Hooke och Jeeves; kardiovaskulära modeller;

    Abstract : Developing models of the cardiovascular system that simulates the dynamic behavior of a virtual patient’s condition is fundamental in the medical domain for predictive outcome and hypothesis generation. These models are usually described through Ordinary Differential Equation (ODE). READ MORE

  5. 24. Measuring the impact of noise on quantum Fourier transforms

    University essay from KTH/Datavetenskap

    Author : Arami Alfarhani; Elias Gustafsson; [2022]
    Keywords : ;

    Abstract : The field of quantum computing has progressed quickly during recent years, but errors caused by quantum noise still remain as a major issue that prevents accurate computations from being performed on quantum computers. In this study, we measure the impact that these errors have on one of the most fundamental quantum operations, the quantum Fourier transform. READ MORE

  6. 25. Anomaly Detection in Log Files Using Machine Learning Techniques

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Author : Lakshmi Geethanjali Mandagondi; [2021]
    Keywords : Anomaly Detection; Log Files; Machine Learning; Clustering; Outlier Detection;

    Abstract : Context: Log files are produced in most larger computer systems today which contain highly valuable information about the behavior of the system and thus they are consulted fairly often in order to analyze behavioral aspects of the system. Because of the very high number of log entries produced in some systems, it is however extremely difficult to seek out relevant information in these files. READ MORE
