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

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

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

    Sammanfattning : 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. LÄS MER

  3. 2. Reconstructing point patterns from spatially aggregated data

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

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

    Sammanfattning : 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. Är alla personuppgifter direkt eller indirekt känsliga? – Om yttergränserna för tillämpningen av artikel 9 i GDPR i ljuset av C-184/20 Etikosdomen

    Magister-uppsats, Göteborgs universitet/Juridiska institutionen

    Författare :Arad Aslrousta; [2024-03-05]
    Nyckelord :General Data Protection Regulation GDPR ; Article 9; Indirect; Indicative; Unambiguous; Sensitive; Personal data; Intellectual operation; Probability; Purposive approach; Contextual approach; The precautionary principle; Principle of proportionality; Freedom to conduct a business;

    Sammanfattning : In August 2022, the CJEU confirmed the existence of indirectly sensitive personal data, leaving critical questions unanswered. While certain data may unequivocally and indirectly disclose sensitive information, a vast amount of data can be used to indirectly deduce such sensitive data only through mere indication. LÄS MER

  5. 4. HAR DAGENS UNGA FUNNIT HJÄRNAN I FÖRTID? En kvantitativ studie över förstagångsväljarnas politiska positionering åren 1992–2021

    Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Lejla Grebic; [2024-02-27]
    Nyckelord :young voters; left-right dimension; GAL-TAN; taxes; migration;

    Sammanfattning : This study explores the political inclinations of young voters over a period for the last 30 years (1992- 2021), focusing on the question of whether there has been a political shift among the young population. Usually, the assumptions are that young voters are more liberal and take a position to the left on the political dimension. LÄS MER

  7. 5. Adherence in patients with heart failure. Relationships to symptom burden and hospitalization frequency : A cross-sectional survey study

    Master-uppsats, Malmö universitet/Institutionen för vårdvetenskap (VV)

    Författare :Helen Moe; [2024]
    Nyckelord :Adherence; Cross sectional study; Heart failure; Hospitalization-frequency; Non-adherence; Symptom burden;

    Sammanfattning : Aim: The aim of the study was to investigate the degree of adherence and non-adherence to treatment regimen in the population with heart failure, as well as to explore relationships to symptom burden and hospitalization-frequency. Introduction: Heart failure – a chronic disease with a somber prognosis and high mortality, incidence and prevalence increasing world-wide. LÄS MER
