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. Svenska fastighetsbolags prestation i perioder av ekonomisk osäkerhet En kvantitativ jämförelse av kommersiella och icke-kommersiella fastighetsbolag av olika åldrar

   Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

   Författare :Jacob Bergqvist; Marcus Lundgren; [2024-03-07]
   Nyckelord :;

   Sammanfattning : The purpose of the report is to describe how interest rates have affected real estate companies in recent years and if the effects vary depending on the founding year of the company (before or after 1994) or the type of properties they manage (residential, commercial and community properties). The research questions were addressed through a quantitative approach, focusing on key metrics such as profit margin, EBITDA margin, rental income, financial net, vacancy rate, loan-to-value ratio, and solidity.

5. 4. Alternative business models for Swedish real estate developers Analysis of alternative business models applied by real estate developers in Sweden to manage macroeconomic challenges

   Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

   Författare :Marcus Edh; Douglas Edhage; Björn Jonasson; [2024-03-06]
   Nyckelord :;

   Sammanfattning : The current macroeconomic climate, with rising inflation and interest rate, is posing a significant challenge for real estate development firms in Sweden. The cost of developing properties is increasing and it is becoming increasingly difficult for many potential buyers to meet the high requirements for down payments associated with the traditional model of home ownership.

7. 5. 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
