  1. 11. Stochastic dynamic modelling and statistical analysis of infectious disease spread and cancer treatment

    Författare :Theresa Stocks; Tom Britton; Michael Höhle; Daniela De Angelis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical modelling; infectious disease spread; cancer treatment; statistical inference; population dynamics; birth-death process; partially observed Markov process; Mathematical Statistics; matematisk statistik;

    Sammanfattning : Mathematical models have proven valuable for public health decision makers as they can provide insights into the understanding, control and, ultimately, the prevention of diseases. This thesis contains four manuscripts dealing with stochastic dynamic modelling and statistical analysis of infectious disease spread and optimization of cancer treatment. LÄS MER

  3. 12. Reinforcement Learning and Dynamical Systems

    Författare :Björn Lindenberg; Karl-Olof Lindahl; Marc G. Bellemare; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial intelligence; distributional reinforcement learning; Markov decision processes; Bellman operators; deep learning; multi-armed bandits; Bayesian bandits; conjugate priors; Thompson sampling; linear finite dynamical systems; cycle orbits; fixed-point systems; Mathematics; Matematik; Computer Science; Datavetenskap;

    Sammanfattning : This thesis concerns reinforcement learning and dynamical systems in finite discrete problem domains. Artificial intelligence studies through reinforcement learning involves developing models and algorithms for scenarios when there is an agent that is interacting with an environment. LÄS MER

  4. 13. Accelerating Monte Carlo methods for Bayesian inference in dynamical models

    Författare :Johan Dahlin; Thomas B. Schön; Fredrik Lindsten; Richard Everitt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computational statistics; Monte Carlo; Markov chains; Particle filters; Machine learning; Bayesian optimisation; Approximate Bayesian Computations; Gaussian processes; Particle Metropolis-Hastings; Approximate inference; Pseudo-marginal methods;

    Sammanfattning : Making decisions and predictions from noisy observations are two important and challenging problems in many areas of society. Some examples of applications are recommendation systems for online shopping and streaming services, connecting genes with certain diseases and modelling climate change. LÄS MER

  5. 14. Health promotion and fall prevention for older people : impact, relevance and economic justification for decision making in a municipality context

    Författare :Saranda Bajraktari; Marlene Sandlund; Magnus Zingmark; Erik Rosendahl; Beatrice Pettersson; Erja Portegijs; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Older people; health promotion; primary prevention; falls prevention; digital health; mHealth; healthy ageing; self-management; reach; cost-effectiveness; self-reported health outcomes; knowledge translation; impact; Public health; folkhälsa; Public health; folkhälsa;

    Sammanfattning : Background: The proportion of older people is increasing and calls for a shift towards proactive approaches to support healthy ageing. The evidence base on health-promoting and preventive interventions (HPP) is promising in terms of maintaining health in older people, but for such interventions to have an impact on population health, translation of evidence to practice is crucial.

  7. 15. Probabilistic modeling in sports, finance and weather

    Författare :Jan Lennartsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical modelling; Game theory; Team sport tactics; Modern portfolio theory; Gaussian fields; Team sport tactics;

    Sammanfattning : In this thesis, we build mathematical and statistical models for a wide variety of real world applications. The mathematical models include applications in team sport tactics and optimal portfolio selection, while the statistical modeling concerns weather and specifically precipitation. LÄS MER
