  1. 1. Parameter Estimation : Towards Data-Driven and Privacy Preserving Approaches

    Författare :Braghadeesh Lakshminarayanan; Cristian R. Rojas; Simone Garatti; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter estimation; System identification;

    Sammanfattning : Parameter estimation is a pivotal task across various domains such as system identification, statistics, and machine learning. The literature presents numerous estimation procedures, many of which are backed by well-studied asymptotic properties. LÄS MER

  3. 2. Automatic Instance-based Tailoring of Parameter Settings for Metaheuristics

    Författare :Felix Dobslaw; Theo Kanter; Åke Malmberg; Thomas Bartz-Beielstein; Mittuniversitetet; []
    Nyckelord :Algorithm Configuration; Parameter Tuning; Parameter Control; Metaheuristics;

    Sammanfattning : Many industrial problems in various fields, such as logistics, process management, orproduct design, can be formalized and expressed as optimization problems in order tomake them solvable by optimization algorithms. However, solvers that guarantee thefinding of optimal solutions (complete) can in practice be unacceptably slow. LÄS MER

  4. 3. Parameter Estimation of a DOC from Engine Rig Experiments

    Författare :Björn Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariate Data Analysis; Parameter Estimation; Exhaust Aftertreatment Modeling; Design of Experiments; Engine Test Bench; DOC; Full Scale;

    Sammanfattning : In this thesis methods of parameter estimation of a Diesel Oxidation Catalyst (DOC) from engine rig experiments were investigated. The investigation did not only include methods of parameter fitting to experimental data but a large effort was also put into catalyst modeling and experimental design. LÄS MER

  5. 4. Aspects of Efficient Parameter Estimation for Diesel Oxidation Catalysts

    Författare :Björn Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MVDA; Mass Transport Modeling; Engine Test Bench; Design of Experiments; Kinetic modeling; DOC; Full Scale; Parameter Estimation; Exhaust Aftertreatment Modeling;

    Sammanfattning : In this thesis the objective was to tune the model parameters of diesel oxidation catalysts (DOC) to measurement data from engine rig experiments in an efficient manner. The scope was however not limited to the algorithm of parameter search alone but instead included the whole process starting with the design of experiments. LÄS MER

  7. 5. Tackling the Uncertainties of Event Generators

    Författare :Leif Gellersen; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QCD; Phenomenology; Parton Showers; Matrix Element Merging; Tuning;

    Sammanfattning : This thesis is composed of four papers, which concern Monte Carlo event generators for high energy particle physics. Precise predictions of the outcome of particle collisions are important for the exploration of the Standard Model of particle physics at collider experiments like the LHC at CERN. LÄS MER
