  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. SAKTA NER ELLER SKROLLA VIDARE? En studie av användarna på TikTok om sin upplevelse av korta medieformat och dess påverkan

    Kandidat-uppsats, Göteborgs universitet/Institutionen för journalistik, medier och kommunikation

    Författare :Alana Cornéer; [2024-03-04]
    Nyckelord :TikTok; koncentrationsförmåga; uppmärksamhet; korta medieformat;

    Sammanfattning : This study delves into the user experiences and perceptions of short media formats on TikTok and their impact on users' attention spans. Drawing from theoretical frameworks such as attention theory, media ecology, and uses and gratifications theory, the study conducted qualitative interviews with six participants to delve deeper into their experiences.

  4. 3. Prevalent Discord. Exploring and estimating the prevalence of the type of user disagreement on news media Facebook posts discussing the Colombian peace process (2020-2022)

    Master-uppsats, Lunds universitet/Graduate School

    Författare :Luis Felipe Villota Macias; [2024]
    Nyckelord :Agonistic peace; antagonism; big data analytics; binary logistic regression; computational content analysis; Colombia; Colombian peace process; discord; Facebook; machine learning; peace process; public opinion and sentiment; social media; Law and Political Science; Social Sciences;

    Sammanfattning : This thesis is dedicated to exploring and understanding public reactions within negotiated peace settlements based on social media data. Concretely, to modeling public opinion and sentiment within the context of the Colombian peace process using a curated dataset of N= ~1. LÄS MER

  5. 4. Robust Object Recognition and Tracking with Drones

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Jiaying Wu; [2024]
    Nyckelord :;

    Sammanfattning : The Skara Skyddsängel project explores an innovative method of providing illumination for cyclists along a 20km unlit bike lane using drones. Current GNSS approach performs generally well but further improvements are need for better robustness. Consequently, this thesis project is raised to seek a robust solution in the field of computer vision. LÄS MER

  7. 5. Hunting the hunters - Evaluating a new method of Geographic Profiling

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Max Pröckl; [2024]
    Nyckelord :rgeoprofile; crimestat; journey-to-crime; geographic profiling; qgis; geographical profiling; Örebromannen; Kim Rossmo; David Canter; Ned Levine.; Law and Political Science;

    Sammanfattning : Geographic Profiling (GP) may be used when searching for an unknown offender by applying mathematical algorithms to geographical information. This thesis aimed to contribute to improvement of the efficiacy of GP’s produced by law enforcement by evaluating a the new Spaulding/Morris Centrographic (SMC)-method of GP that claims to counteract two of the main difficulties when constructing a GP in a real world investigation: 1.
