    University essay from Uppsala universitet/Analys och partiella differentialekvationer

    Author : Petter Gunnarsson; [2023]
    Keywords : clifford algebra; hypercomplex number; octonion;

    Abstract : This is an overview of geometric algebras in dimensions 0-4 from the perspective of the concept of number itself. It is developed from a historic viewpoint and investigates and develops a pedagogic approach emphasizing the geometric aspects of the subject. READ MORE

  5. 4. Itô Diffusions on Level Sets

    University essay from Uppsala universitet/Analys och partiella differentialekvationer; Uppsala universitet/Statistik, AI och data science

    Author : Coën Olofsson; [2023]
    Keywords : Itô diffusions; level sets; stochastic differential geometry; numerical schemes;

    Abstract : Itô diffusions that move on level sets of functions in Rn, which we have called level processes, are an overlooked variant of the classical Itô processes. These processes find themselves nestled between the study of regular Itô diffusions in Rn and diffusions which are bound to smooth manifolds. READ MORE

  6. 5. Prediction of nickel product prices with LSTM

    University essay from Uppsala universitet/Analys och partiella differentialekvationer

    Author : Daniella Rosendahl; [2023]
    Keywords : LSTM; ML; Machine learning;

    Abstract : Prediction of future stock markets has long been, and will continue to be a relevant topic. However, predicting markets is one of the most challenging areas to work with due to the unpredictability of the market. The extent to which markets can be predicted is a debated subject that has not yet been answered. READ MORE
