  2. 16. Event Prediction and Bootstrap in Time Series

    Author : Anders Svensson; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; bootstrap control.; statistical bootstrap; catastrophe; level-crossings; ARMAX process; Optimal alarm system; time series; optimal event predictor; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : Alarm systems are used in many situations, and should be as efficient as possible. In this thesis optimal predictive alarm systems, event predictors, are presented for general linear time series models with external signals. This family of process models include e.g. READ MORE

  4. 17. Family studies of schizophrenia and pregnancy outcomes

    Author : Anna Svensson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alternating logistic regression; environment; familial aggregation; fertility; generalized estimating equations; genes; obstetric complications; preterm birth; siblings; schizophrenia; small for gestational age; variance components;

    Abstract : Why do psychiatric diseases run in families? Why do some women tend to have similar obstetric complications in subsequent pregnancies? The overall aim of this thesis was to investigate how genes and environments contribute to the aggregation of schizophrenia and adverse pregnancy outcomes in some families. Further, we also studied the fertility in families of patients with schizophrenia. READ MORE

  5. 18. Intravenous contrast media optimization at computed tomography

    Author : Anders Svensson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The administration of intravenous contrast media (IV CM) is essential for detecting lesions at most computed tomography (CT) examinations. The overall aim of this thesis is to investigate different aspects of IV CM administration that may affect the quality of the CT examination. READ MORE

  6. 19. Learning probabilistic models of dynamical phenomena using particle filters

    Author : Andreas Svensson; Thomas B. Schön; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Dynamical behavior can be seen in many real-life phenomena, typically as a dependence over time. This thesis studies and develops methods and probabilistic models for statistical learning of such dynamical phenomena.A probabilistic model is a mathematical model expressed using probability theory.

  7. 20. Machine learning with state-space models, Gaussian processes and Monte Carlo methods

    Author : Andreas Svensson; Thomas B. Schön; Fredrik Lindsten; Carl Edward Rasmussen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Machine learning; State-space models; Gaussian processes; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Numbers are present everywhere, and when they are collected and recorded we refer to them as data. Machine learning is the science of learning mathematical models from data. Such models, once learned from data, can be used to draw conclusions, understand behavior, predict future evolution, and make decisions. READ MORE
