  1. 1. Probabilistic Sequence Models with Speech and Language Applications

    Författare :Gustav Eje Henter; W. Bastiaan Kleijn; Arne Leijon; Gernot Kubin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time series; acoustic modelling; speech synthesis; stochastic processes; causal-state splitting reconstruction; robust causal states; pattern discovery; Markov models; HMMs; nonparametric models; Gaussian processes; Gaussian process dynamical models; nonlinear Kalman filters; information theory; minimum entropy rate simplification; kernel density estimation; time-series bootstrap;

    Sammanfattning : Series data, sequences of measured values, are ubiquitous. Whenever observations are made along a path in space or time, a data sequence results. To comprehend nature and shape it to our will, or to make informed decisions based on what we know, we need methods to make sense of such data. LÄS MER

  3. 2. Evolutionary Approaches to Sequence Alignment

    Författare :Marcin Bogusz; Simon Whelan; Jeffrey Thorne; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular evolution; multiple sequence alignment; pair hidden Markov models; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Molecular evolutionary biology allows us to look into the past by analyzing sequences of amino acids or nucleotides. These analyses can be very complex, often involving advanced statistical models of sequence evolution to construct phylogenetic trees, study the patterns of natural selection and perform a number of other evolutionary studies.

  4. 3. Applied Speech Enhancement for Personal Communication

    Författare :Nils Westerlund; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech Enhancement; Active Noise Control;

    Sammanfattning : In our daily life noise is almost constantly present. At the same time our need to communicate reliably has probably never been this great. Surrounding noise impairs our ability to communicate by speech and causes the users of a speech communication system to strain both their hearing and their voices. LÄS MER

  5. 4. Bioinformatic methods in protein characterization

    Författare :Yvonne Kallberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bioinformatic methods in protein characterization;

    Sammanfattning : Bioinformatics is an emerging interdisciplinary research field in which mathematics. computer science and biology meet. In this thesis. bioinformatic methods for analysis of functional and structural properties among proteins will be presented. LÄS MER

  7. 5. Machine learning and data-parallel processing for viral metagenomics

    Författare :Zurab Bzhalava; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : More than 2 million cancer cases around the world each year are caused by viruses. In addition, there are epidemiological indications that other cancer-associated viruses may also exist. However, the identification of highly divergent and yet unknown viruses in human biospecimens is one of the biggest challenges in bio- informatics. LÄS MER
