  1. 1. 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

  2. 2. Sparse Modeling Heuristics for Parameter Estimation - Applications in Statistical Signal Processing

    Författare :Stefan Ingi Adalbjörnsson; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parameter estimation; sparse models; convex optimization; fundamental frequency; inharmonicity; audio localization; symbolic periodicity; alternating directions method of multipliers; N-dimensional decaying sinusoids.;

    Sammanfattning : This thesis examines sparse statistical modeling on a range of applications in audio modeling, audio localizations, DNA sequencing, and spectroscopy. In the examined cases, the resulting estimation problems are computationally cumbersome, both as one often suffers from a lack of model order knowledge for this form of problems, but also due to the high dimensionality of the parameter spaces, which typically also yield optimization problems with numerous local minima.

  3. 3. Academic Performance in Swedish Ninth Grade Students Treated for Brain Tumours

    Författare :Malin Lönnerblad; Eva Berglund; Klas Blomgren; Ingrid van’t Hooft; Lisa Thorell; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; School performance; academic performance; brain tumour; academic grades; national tests; delayed graduation; theoretical subjects; practical and aesthetic subjects; specialpedagogik; Special Education;

    Sammanfattning : The overall aim of this thesis was to investigate how children in Sweden treated for brain tumours performed in their ninth year at school compared with matched controls. The studies investigated grades and results from national tests in the theoretical subjects of Swedish, English, and mathematics; grades in the practical and aesthetic subjects of art, crafts, music, home and consumer studies, physical education and health; and the frequency of delayed graduation and qualification for school years 10-12 (corresponding to upper-secondary school or high school).
