  1. 1. Data Driven Visual Recognition

    Författare :Omid Aghazadeh; Stefan Carlsson; Jiri Matas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Visual Recognition; Data Driven; Supervised Learning; Mixture Models; Non-Parametric Models; Category Recognition; Novelty Detection;

    Sammanfattning : This thesis is mostly about supervised visual recognition problems. Based on a general definition of categories, the contents are divided into two parts: one which models categories and one which is not category based. We are interested in data driven solutions for both kinds of problems. LÄS MER

  3. 2. A Non-Stationary perspective on the European and Swedish Business Cycle

    Författare :Louise Holm; Högskolan i Skövde; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business cycles; business cycle dating; non-parametric smoothing; non-stationarity; recession prediction; interest rate spread; binary respons models; Business and economics; Ekonomi; Humanities and Social sciences; Humaniora-samhällsvetenskap; Business cycles; business cycle dating; non-parametric smoothing; non-stationarity; recession prediction; interest rate spread; binary response models.;

    Sammanfattning : Business cycles, the ups and downs observed somewhat simultaneously in numerous macroeconomic variables in an economy and often measured using real GDP, are important and, despite much economic research, still incom- pletely understood. Dating the business cycle has always been of interest in macroeconomic research. LÄS MER

  4. 3. Statistical analysis and simulation methods related to load-sharing models

    Författare :Patrik Rydén; Yuri Belyaev; Uwe Jensen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Non-parametric and parametric estimation; load-sharing models; asymptotic distribution; martingale; resampling; life testing; reliability;

    Sammanfattning : We consider the problem of estimating the reliability of bundles constructed of several fibres, given a particular kind of censored data. The bundles consist of several fibres which have their own independent identically dis-tributed failure stresses (i.e.the forces that destroy the fibres). LÄS MER

    Sammanfattning : This thesis analyses educational investments and labour market attachment for refugee immigrants who received a permanent visa to Sweden during 1987-1991. It consists of five self-contained chapters. LÄS MER

  7. 5. Modelling transport, accessibility and productivity in Öresund

    Författare :Tom Petersen; KTH; []
    Nyckelord :infrastructure assessment; regional consequences; validation; microlevel panel data; non-parametric method;

    Sammanfattning : This licentiate thesis is about the provision of transportinfrastructure and the regional impacts of such provision.Three different techniques have been investigated that can beused for the assessment and forecasting of the effects ofinfrastructure: transport demand models and parametric andnon-parametric econometric estimation techniques.
