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. Elektrifiering och lönsamhet i bilbranschen

   Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

   Nyckelord :;

   Sammanfattning : The most prominent trend in the automotive industry right now is electrification. Consumers and global regulations force companies to offer more environmentally friendly alternatives to the fossil car. But sustainable development is not only about offering environmentally friendly alternatives. It must also be economically feasible. LÄS MER

4. 3. DE FREDSBEVARANDE OPERATIONERNAS KRITISKA VÄN En kvantitativ undersökning av Kinas deltagande i FN:s fredsbevarande operationer mellan 1991 och 2017

   Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

   Författare :Albin Carlsson; [2024-03-01]
   Nyckelord :United Nations; China; Liberal peacebuilding; Peacekeeping; Liberal peace; International relations;

   Sammanfattning : The United Nations’ peacekeeping missions have, since the end of the cold war, become increasingly characterised by liberal goals through the phenomenon of liberal peacebuilding. At the same time, China has become an active participant in peacekeeping while simultaneously criticising those liberal ambitions. LÄS MER

5. 4. An attempt to promote ground-nesting bees in an urban landscape. Investigating the use of sand beds as a conservation effort.

   Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Författare :Bodil Mattson; [2024-02-16]
   Nyckelord :ground-nesting bees - pollinator conservation - sand beds – conservation in urban parks;

   Sammanfattning : Pollinators provide crucial services for the ecosystems by pollinating around 80-90% of all plants. However, pollinating insects are declining worldwide which may cause a parallel decline in plant species leading to large biodiversity losses. LÄS MER

7. 5. Simulating Mobility of Large Population using Mobile Application Data

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

   Författare :Mattias Rydström; Diana Salim; [2024-01-23]
   Nyckelord :Human mobility; mobile application data; synthesize activity plans;

   Sammanfattning : Understanding people’s travel patterns and knowing the frequency of their travel activities provide important insights for effective transport management and infrastructure planning. While traditional travel surveys have historically contributed to this valuable information, they come with shortcomings such as being expensive to collect, easily outdated, and having short time coverage.
