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

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

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

    Abstract : 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. READ MORE

  2. 2. An Ontological Representation for the Real-Time Evaluation of Vaccine Coverage, Safety, and Effectiveness

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Elise Lång; [2023]
    Keywords : Ontology; Vaccine evaluation; FAIR principles; Ontology evaluation;

    Abstract : Data used when studying vaccination programs and vaccine evaluations are collectedfrom multiple, and constantly changing data sources. These data sources are often isolateddata silos, that are hard for researchers and public health organizations to connect, andthus hinders when researchers and public health organizations are conducting these studies.

  3. 3. Modelling Gas Flow Behaviour in Gas Atomizer

    University essay from KTH/Materialvetenskap

    Author : Aravind Senan Vasanthasenan Reji; [2022]
    Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

    Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

  4. 4. Visualizing issue tracking data using a process mining tool to support the agile maturity assessment within the Scaled Agile Framework : A case study

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Olle Hovmark; [2022]
    Keywords : Processmining; Agilematurity; Visualization; Issuetrackingsystem; Software Process Improvement; The Scaled Agile Framework; Inductive visual Miner; Process mining; Agil mognad; Visualisering; Ärendehanteringssystem; Mjukvaruprocessförbättring; The Scaled Agile Framework; Inductive visual Miner;

    Abstract : Today, agile development is broadly used within both small and large organizations worldwide. Transitioning to agile development in a large organization is a complex task that requires support from everyone in it. The Scaled Agile Framework (SAFe) is a framework meant to help integrate agile development within all parts of an organization. READ MORE

  5. 5. VFR Leisure Experiences of Italians and Chinese in Sweden  : A New Study Approach to Migrants’ Personal Networks Influence on Place Participation During (im)mobility Times

    University essay from Malmö universitet/Institutionen för globala politiska studier (GPS)

    Author : Sara Fiorella Viviana Licata; [2022]
    Keywords : Highly skilled migrants; Chinese; Italians; Sweden; Personal networks; Immobility; VFR tourism; Place participation; Multicultural societies;

    Abstract : This thesis explores the Visit Friends and Relatives (VFR) tourism experiences of highly skilled first-generation Italians and Chinese in Sweden. It focuses on personal networks influence on migrant hosts’ interaction and participation in the place and how the Covid-19 global immobility has changed the dynamics and the feelings towards the place.
