  1. 1. Stochastic claims reserving in non-life insurance : Bootstrap and smoothing models

    Författare :Susanna Björkwall; Ola Hössjer; Esbjörn Ohlsson; Peter England; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bootstrap; Chain-ladder; Generalized linear model; Separation method; Smoothing; Stochastic claims reserving; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Sammanfattning : In practice there is a long tradition of actuaries calculating reserve estimates according to deterministic methods without explicit reference to a stochastic model. For instance, the chain-ladder was originally a deterministic reserving method. LÄS MER

  3. 2. Sound Quality of Flue Organ Pipe. An Interdisciplinary Study on the Art of Voicing

    Författare :Vincent Rioux; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; listening tests; psychoacoustics; verbal descriptors; flue organ pipes; musical acoustics; sound quality; deterministic stochastic separation; timbre; time-frequency analysis;

    Sammanfattning : This thesis presents a research study carried out in collaboration with a department of applied acoustics, a department of musical acoustics and an organ workshop. The description of the sound quality of flue organ pipes has received fairly little attention either in organ-building or scientific literature, despite its importance in the overall quality of the instrument, probably due to the difficulties inherent in doing so.

  4. 3. The ubiquitous signal processing : Applications to communications, spectral analysis and array processing

    Författare :Erik G. Larsson; Björn Ottersten; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital signal processing; array processing; spectral analysis; incomplete data; wireless communications; space-time coding; synthetic aperture radar imaging; signal separation; estimation; detection; Signal processing; Signalbehandling; Signal Processing; Signalbehandling;

    Sammanfattning : This dissertation is concerned with statistical signal processing and its applications. The thesis consists of three parts: I) applications to wireless communications, II) applications to spectral analysis and III) applications to array processing. LÄS MER

  5. 4. Breaking the Dimensionality Curse of Voronoi Tessellations

    Författare :Vladislav Polianskii; Florian T. Pokorny; Michael Bronstein; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geometric methods; machine learning methods; Voronoi; Delaunay; high dimensional geometry; curse of dimensionality; monte carlo; Datalogi; Computer Science;

    Sammanfattning : Considering the broadness of the area of artificial intelligence, interpretations of the underlying methodologies can be commonly narrowed down to either a probabilistic or a geometric point of view. Such separation is especially prevalent in more classical "pre-neural-network" machine learning if one compares Bayesian modelling with more deterministic models like nearest neighbors. LÄS MER

  7. 5. On Detection and Estimation of Multiple Sources in Radar Array Processing

    Författare :Jonny Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatially correlated noise; Cramer-Rao bounds; estimation; feature reduction; virtual uniform linear arrays; classification; adaptive data reduction; nonlinear weighted least squares; multiple targets; detection;

    Sammanfattning : This thesis deals with detection and estimation problems in sensor array signal processing. We treat the multiple hypothesis problem for complex sinusoids observed in spatially colored noise. LÄS MER
