  1. 1. MetaStackVis: Visually-Assisted Performance Evaluation of Metamodels in Stacking Ensemble Learning

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Ilya Ploshchik; [2023]
    Nyckelord :Visualization; interaction; metamodels; validation metrics; predicted probabilities; stacking; stacked generalization; ensemble learning; machine learning;

    Sammanfattning : Stacking, also known as stacked generalization, is a method of ensemble learning where multiple base models are trained on the same dataset, and their predictions are used as input for one or more metamodels in an extra layer. This technique can lead to improved performance compared to single layer ensembles, but often requires a time-consuming trial-and-error process. LÄS MER

  3. 2. From Topology Optimized Concept to Detailed Design via Implicit-based Geometries and Non-linear Finite Element Analysis

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Jonatan Gripenberth; [2023]
    Nyckelord :Topologioptimiering; Implicita kroppar; Arbetsflöde; Icke-linjär finita element analys;

    Sammanfattning : A workflow to go from topology optimized concept to a detailed design was created in this thesis. This was done through the use of Implicit-based geometries and Non-linear finite element analysis. LÄS MER

  4. 3. A systematic mapping study of mapping modelling languages

    Magister-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Marija Popovic; Amila Cizmic; [2022]
    Nyckelord :mapping; mapping model; mapping metamodel; mapping language;

    Sammanfattning : Context - Various research teams, as well as individual researchers, have investigated mapping modelling languages. However, systematic studies that provide a structured overview of this research on this topic have not been conducted. It is noticeable that this leaves a big gap in the context of a modelling language. LÄS MER

  5. 4. An Empirical Study on Software Modeling Curricula

    Magister-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Redion Lila; Alban Delishi; [2022]
    Nyckelord :software modeling; software engineering; metamodel; survey; modeling tools; modeling languages;

    Sammanfattning : Background: Software Engineering is a high-demand field constantly changing with new languages, tools, and frameworks. The use of software modeling in Software Engineering is essential for solving complex problems since it helps the developer understand abstraction and develop high-level code. LÄS MER

  7. 5. Meta-Modelling Based Design Optimization of Gas Turbine Blade Cooling Channels

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Namita Sharma; [2021]
    Nyckelord :Machine Learning; Meta Model; Data Science;

    Sammanfattning : The aim of this paper is to investigate the use of Machine Learning to accelerate the processof gas turbine design optimization. Traditionally, the process simulations involved inoptimization are performed using commercial Computational Fluid Dynamics (CFD) softwaretools to find the best combinations of design parameters under specific conditionsand operational constraints.
