  1. 1. Stochastic Frank-Wolfe Algorithm : Uniform Sampling Without Replacement

    Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Olof Håkman; [2023]
    Nyckelord :Stochastic Frank-Wolfe; Stochastic optimization; Sampling without replacement;

    Sammanfattning : The Frank-Wolfe (FW) optimization algorithm, due to its projection free property, has gained popularity in recent years with typical application within the field of machine learning. In the stochastic setting, it is still relatively understudied in comparison to the more expensive projected method of Stochastic Gradient Descent (SGD). LÄS MER

  3. 2. Boltzmann Equation and Discrete Velocity Models : A discrete velocity model for polyatomic molecules

    Kandidat-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Olof Håkman; [2019]
    Nyckelord :Boltzmann equation; Discrete velocity models; Polyatomic molecules;

    Sammanfattning : In the study of kinetic theory and especially in the study of rarefied gas dynamics one often turns to the Boltzmann equation. The mathematical theory developed by Ludwig Boltzmann was at first sight applicable in aerospace engineering and fluid mechanics. LÄS MER
