  1. 1. Feature Selection for Microarray Data via Stochastic Approximation

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Erik Rosvall; [2024-03-18]
    Keywords : feature selection; feature ranking; microarray data; stochastic approximation; Barzilai and Borwein method; Machine Learning; AI;

    Abstract : This thesis explores the challenge of feature selection (FS) in machine learning, which involves reducing the dimensionality of data. The selection of a relevant subset of features from a larger pool has demonstrated its effectiveness in enhancing the performance of various machine learning algorithms. READ MORE

  3. 2. Reconstructing point patterns from spatially aggregated data

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Jens Michelsen; [2024-03-13]
    Keywords : lorem; ipsum; dolor; sit; amet; consectetur; adipisicing; elit; sed; do.;

    Abstract : In this thesis we explore the ability to reconstruct samples (point configurations) from a point process, based only on the information contained in spatially aggregated data, namely the number of points in the partitions of a larger region. The ability to reconstruct a point configuration, in such a way that it retains most of it’s statistical properties, could be useful in cases where one is faced with a mixed dataset; some regions containing the full point configuration data, while other regions only contain aggregated data, i.

  4. 3. THE INCONSISTENT WELFARE STANCES OF AN INCOHERENT PARTY FAMILY A statistical analysis of the effect of welfare salience on the welfare positions of radical right parties

    University essay from Göteborgs universitet/Statsvetenskapliga institutionen

    Author : Karin Zwinkels; [2024-01-19]
    Keywords : ;

    Abstract : The radical right is held together as a party family by their positions on sociocultural issues like immigration and law and order, while displaying a relatively large variation over time and across countries on socioeconomic issues. Since it is becoming more and more common for radical right parties in Western Europe to take part in government, it is however important to know what to expect from them in all policy areas and not just those that are at the core of their ideology.

    University essay from Lunds universitet/Statistiska institutionen

    Author : Elias Gullberg; [2024]
    Keywords : Linear Mixed Models; Mathematics and Statistics;

    Abstract : Barnviken in Malmö has persistently encountered challenges associated with elevated concentrations of Escherichia coli (E. coli) without a discernible source of contamination. READ MORE

  6. 5. Investigation of Injury Predictors for Rat Neuro Trauma

    Author : Rosetta Maglio; [2024]
    Keywords : Finite element method; Rat brain traumatic brain injury; Rat brain finite element model; Strain; Strain rate; Product of strain and strain rate; Rotational direction; Rotational duration; Injury prediction; Finita elementmetoden; Råtthjärnans finita elementmodell; Belastning; Belastningshastighet; Produkten av belastning och belastningshastighet; Rotationsriktning; Rotationstid; Skadeförutsägelse;

    Abstract : A traumatic brain injury is usually caused by a direct impact to the head and is a common cause of disability and death all around the world. The most effective method to predict brain injury today, is to use a finite element head model. READ MORE
