1. 26. Enhancing person re-identification: leveraging DensePose for improving occlusion handling and generalization

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Björn Elwin; Anton Fredriksson; [2023]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : In this master’s thesis we propose a DensePose-based person re-identification (re-ID) machine learning algorithm building upon previous research on this topic. DensePose, a deep neural network that performs human body part segmentation on images, forms the foundation of our approach. LÄS MER

3. 27. Machine Learning Algorithms to Predict Cost Account Codes in an ERP System : An Exploratory Case Study

   Kandidat-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Alexander Wirdemo; [2023]
   Nyckelord :Artificial Intelligence; Machine Learning; ERP; invoice automation; RPA; Random forest; Naïve Bayes; k-Nearest Neighbor; Artificiell Intelligens; maskinlärning; ERP; fakturaautomation; RPA; Random forest; Naïve Bayes; k-Nearest Neighbor;

   Sammanfattning : This study aimed to investigate how Machine Learning (ML) algorithms can be used to predict the cost account code to be used when handling invoices in an Enterprise Resource Planning (ERP) system commonly found in the Swedish public sector. This implied testing which one of the tested algorithms that performs the best and what criteria that need to be met in order to perform the best. LÄS MER

4. 28. Quantifying the Impact of EU-US "Distressed" Financial Market Integration on European Credit Supply

   Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

   Författare :Ioannis Tzoumas; [2023]
   Nyckelord :ΔCoVaR; Loans; Credit; Risk; Integration; Business and Economics;

   Sammanfattning : This paper proposes a new method for quantifying financial integration by adapting Adrian & Brunnermeier (2016)’s ΔCoVaR to conform with standard asset pricing literature (Lewellen & Nagel 2006, Cochrane 2009). We reconcile ΔCoVaR with standard microeconomic theory (Waller & Lewarne 1994) and test for causal relationships with respect to the contagion of US acute financial shocks to the EU’s loan supply.

5. 29. Estimating the load weight of freight trains using machine learning

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Erik Kongpachith; [2023]
   Nyckelord :Railway freight Transport; Rail Vehicle Weighing; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Machine Learning; Regression; Polynomial Regression; Regression Trees; Random Forest Regression; Support Vector Regression; Järnvägsgods transport; Vägning av järnvägsfordon; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Maskininlärning; Regression; Polynom Regression; Regressionsträd; Random Forest Regression; Support Vector Regression;

   Sammanfattning : Accurate estimation of the load weight of freight trains is crucial for ensuring safe, efficient and sustainable rail freight transports. Traditional methods for estimating load weight often suffer from limitations in accuracy and efficiency. LÄS MER

7. 30. The Effect of Monetary Policy and other Macroeconomic Factors on Wealth Inequality in the United States

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Jacob Stridsberg; Alexander Myrberg; [2022-10-24]
   Nyckelord :;

   Sammanfattning : Wealth inequality is a crescent phenomenon and topic that has been gaining attention of late, not least in the United States, but in many other countries as well. This Master’s thesis seeks to discern what factors have been conducive to this increase, chiefly focusing on the role played by the central bank via setting the federal funds rate and its effect on the top 1 percentile’s wealth share.
