  1. 1. Ensemble methods for protein structure prediction

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Marcin J. Skwark; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein structure prediction; model quality assessment; contact prediction; homology modeling; ab-initio prediction; consensus prediction; structural bioinformatics; bioinformatics; protein structure; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

    Sammanfattning : Proteins play an essential role in virtually all of life's processes. Their function is tightly coupled to the three-dimensional structure they adopt.Solving protein structures experimentally is a complicated, time- and resource-consuming endeavor. LÄS MER

  2. 2. Optimal weather routing using ensemble weather forecasts

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Lukas Skoglund; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; route optimization; ensemble weather forecasts;

    Sammanfattning : Ships small and large all battle the elements when crossing the worlds oceans.  As such, ships are designed to operate in situations with high speed winds and heavy waves.  There are however limits to what any ship can handle safely and it is thus important to avoid the worst weather systems as much as possible.

  3. 3. Neural Network Ensembles and Combinatorial Optimization with Applications in Medicine

    Detta är en avhandling från Department of Theoretical Physics, Lund University

    Författare :Henrik Haraldsson; Lund University.; Lunds universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; machine learning; artificial neural networks; ensemble methods; feature extraction; ECG; combinatorial optimization; mean field annealing; Computer science; numerical analysis; systems; Datalogi; control; system; kontroll; Artificial intelligens; Artificiell intelligens; Fysicumarkivet A:2003:Haraldsson;

    Sammanfattning : Artificial neural network (ANN) and combinatorial optimization algorithms are developed, and applied to the medical domain. A novel method for training an ensemble of ANN is presented, based on random weight updates alternated with replication of networks with low error. LÄS MER

  4. 4. Improving diagnosis of acute coronary syndromes in an emergency setting: A machine learning approach

    Detta är en avhandling från Department of Theoretical Physics, Lund University

    Författare :Michael Green; Lund University.; Lunds universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ensemble; artificial neural network; machine learning; acute coronary syndrome; electrocardiogram; case based explanation; decision support system;

    Sammanfattning : Acute coronary syndrome (ACS) is the biggest people killer in the western world today. Despite well trained physicians and reliable diagnostic tools, diagnosing ACS early in the emergency departments (ED) remains a challenge. LÄS MER
