  1. 1. Trustworthy explanations : Improved decision support through well-calibrated uncertainty quantification

    Författare :Helena Löfström; Ulf Seigerroth; Ulf Johansson; Patrick Mikalef; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Explainable Artificial Intelligence; Interpretable Machine Learning; Decision Support Systems; Uncertainty Estimation; Explanation Methods;

    Sammanfattning : The use of Artificial Intelligence (AI) has transformed fields like disease diagnosis and defence. Utilising sophisticated Machine Learning (ML) models, AI predicts future events based on historical data, introducing complexity that challenges understanding and decision-making. LÄS MER

  2. 2. Vacuum Ultraviolet Scanning Photoelectron Microscopy, Instrumentation & Applications

    Författare :Ulf Johansson; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photoelectron Microscopy; Spectromicroscopy; Photoemission; Silicon; Oxide desorption; High-Tc superconductor; Physics; Ellipsoidal mirror; Fysik; Chemistry; Kemi; Fysicumarkivet A:1997:Johansson;

    Sammanfattning : This thesis describes the design and characterisation of a vacuum ultraviolet scanning photoelectron microscope as well as results from studies of laterally inhomogeneous surfaces. The instrument utilises synchrotron radiation from an undulator at the 550 MeV storage ring at the MAX-laboratory. LÄS MER

  3. 3. Obtaining Accurate and Comprehensible Data Mining Models : An Evolutionary Approach

    Författare :Ulf Johansson; Lars Niklasson; Tom Ziemke; Thorsteinn Rögnvaldsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Rule extraction; Ensembles; Data mining; Genetic programming; Artificial neural networks; Computer science; Datalogi;

    Sammanfattning : When performing predictive data mining, the use of ensembles is claimed to virtually guarantee increased accuracy compared to the use of single models. Unfortunately, the problem of how to maximize ensemble accuracy is far from solved. LÄS MER

  4. 4. Det förgångna är framtiden : Ursprungsfolk och självbestämmande i Hawai´i

    Författare :Ulf Johansson Dahre; Socialantropologi; []

    Sammanfattning : The sovereignty- and self-determination movements of indigenous peoples are a salient factor on the political agenda in many western world countries. Indigenous peoples in Hawai´i and elsewhere have become increasingly politicised in hope of changing their relationship with the states within which they are located. LÄS MER
