  1. 16. Scalable Bayesian spatial analysis with Gaussian Markov random fields

    Författare :Per Sidén; Mattias Villani; Anders Eklund; Håvard Rue; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial statistics; Bayesian statistics; Gaussian Markov random fields; fMRI; Machine learning; Spatial statistik; Bayesiansk statistik; Gaussiska Markov-fält; fMRI; Maskininlärning;

    Sammanfattning : Accurate statistical analysis of spatial data is important in many applications. Failing to properly account for spatial autocorrelation may often lead to false conclusions. LÄS MER

  3. 17. Computational Modeling of Cancer Progression

    Författare :Hossein Shahrabi Farahani; Jens Lagergren; Niko Beerenwinkel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer progression; Bayesian networks; microRNA editing; SRA - Molekylär biovetenskap; SRA - Molecular Bioscience;

    Sammanfattning : Cancer is a multi-stage process resulting from accumulation of genetic mutations. Data obtained from assaying a tumor only contains the set of mutations in the tumor and lacks information about their temporal order. Learning the chronological order of the genetic mutations is an important step towards understanding the disease. LÄS MER

  4. 18. Analysis of enterprise IT service availability : Enterprise architecture modeling for assessment, prediction, and decision-making

    Författare :Ulrik Franke; Pontus Johnson; Lars Nordström; Göran Ericsson; João Paulo A. Almeida; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Service Level Agreement; outage costs; Enterprise Architecture; enterprise IT service availability; decision-making; metamodeling; Enterprise Architecture analysis; Bayesian networks; fault trees; Predictive Probabilistic Architecture Modeling Framework; Service Level Agreement; nertidskostnader; Enterprise Architecture; tillgänglighet hos IT-tjänster; beslutsfattande; metamodellering; arkitekturanalys; bayesianska nätverk; felträd; Predictive Probabilistic Architecture Modeling Framework;

    Sammanfattning : Information technology has become increasingly important to individuals and organizations alike. Not only does IT allow us to do what we always did faster and more effectively, but it also allows us to do new things, organize ourselves differently, and work in ways previously unimaginable.

  5. 19. From networks to pathway analysis

    Författare :Miguel Castresana Aguirre; Erik Sonnhammer; Alfonso Valencia; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

    Sammanfattning : Biological mechanisms stem from complex intracellular interactions spanning across different levels of regulation. Mapping these interactions is fundamental for the understanding of all types of biological conditions, including complex diseases. Each experimental approach carries its own bias and noise. LÄS MER

  7. 20. Computer-Assisted Troubleshooting for Efficient Off-board Diagnosis

    Författare :Håkan Warnquist; Patrick Doherty; Jonas Kvarnström; Mattias Nyberg; Erik Frisk; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Automated planning; diagnosis; automotive industry; troubleshooting; Bayesian networks; Computer science; Datavetenskap;

    Sammanfattning : This licentiate thesis considers computer-assisted troubleshooting of complex products such as heavy trucks. The troubleshooting task is to find and repair all faulty components in a malfunctioning system. LÄS MER
