  1. 1. Delayed-acceptance approximate Bayesian computation Markov chain Monte Carlo: faster simulation using a surrogate model

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Andrea Krogdal; [2020-01-09]
    Keywords : ABC; MCMC; delayed acceptance; DA; surrogate model;

    Abstract : The thesis introduces an innovative way of decreasing the computational cost of approximateBayesian computation (ABC) simulations when implemented via Markovchain Monte Carlo (MCMC). Bayesian inference has enjoyed incredible success sincethe beginning of 1990’s thanks to the re-discovery of MCMC procedures, and theavailability of performing personal computers. READ MORE

  2. 2. Nanoscale detection of insulin granule sub-structures using dSTORM imaging

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Yu Hong; [2020]
    Keywords : islet β-cells; dSTORM imaging; Alexa Fluor 647; Physics and Astronomy;

    Abstract : Diabetes mellitus is a global disease, mainly caused by insufficient insulin secre- tion from pancreatic islet β-cells. Insulin is stored in the granules of islet β-cells and released in response to extracellular stimuli e.g. glucose. READ MORE

  3. 3. NSGA-II DESIGN FOR FEATURE SELECTION IN EEG CLASSIFICATION RELATED TO MOTOR IMAGERY

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Robin Johansson; [2020]
    Keywords : ;

    Abstract : Feature selection is an important step regarding Electroencephalogram (EEG) classification, for a Brain-Computer Interface (BCI) systems, related to Motor Imagery (MI), due to large amount of features, and few samples. This makes the classification process computationally expensive, and limits the BCI systems real-time applicability. READ MORE

  4. 4. Topological recursive fitting trees : A framework for interpretable regression extending decision trees

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

    Author : Alexandre Tadros; [2020]
    Keywords : ;

    Abstract : Many real-world machine learning applications need interpretation of an algorithm output. The simplicity of some of the most fundamental machine learning algorithms for regression, such as linear regression or decision trees, facilitates interpretation. However, they fall short when facing complex (e.g. READ MORE

  5. 5. Option Pricing and Early Exercise Boundary of American Options under Markov-Modulated Volatility

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Danny Zina; [2020]
    Keywords : Pricing American Options; Early Exercise Boundary; Markov-Modulated Volatility; Switching-State Volatility; Extended CRR Model.;

    Abstract : The CRR binomial model is one of the most important models in financial mathematics. In this thesis we consider an extension to this model with Markov switching-state volatility. We present a detailed algorithm for obtaining early exercise boundaries for American options, as well as, fair prices for both American and European options. READ MORE
