1. 1. Data Generation in Metal Recycling Using Unconditional Diffusion Models

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Andersson Sebastian; [2023]
   Keywords : Machine learning; diffusion model; unconditional diffusion model; data generation; generative model;

   Abstract : Combitech AB was interested in how to automate the process of annotating aluminum scrap when it was adjacent to other metals. This was to ultimately create an annotated dataset that could be utilized for training a segmentation model. The idea was to make use of generative models to generate samples of general scrap metals.

3. 2. Diffusion Models for Video Prediction and Infilling : Training a conditional video diffusion model for arbitrary video completion tasks

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Tobias Höppe; [2022]
   Keywords : Diffusion; Video prediction and infilling; Conditional generation; Diffusion; Videoförutsägelse och ifyllnad; Villkorad generation;

   Abstract : To predict and anticipate future outcomes or reason about missing information in a sequence is a key ability for agents to be able to make intelligent decisions. This requires strong temporally coherent generative capabilities. READ MORE

4. 3. Value at Risk Estimation with Generative Adversarial Networks

   Abstract : Risk is of large importance for financial institutions and there are many different measures that can be used. A popular one is value at risk (VaR), which is the maximum likely loss for a portfolio of financial assets. Different methods of estimating it has been suggested, one often described is the variance-covariance method. READ MORE

5. 4. An Experimental Study on Gender Differences in Leading-by-Example in a Social Dilemma

   University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Author : Johanna Ohlin; [2021]
   Keywords : leading-by-example; gender differences; sequential public goods game; voluntary contribution; cooperation;

   Abstract : This study examines gender differences in leading-by-example in a social dilemma by the means of an online experiment with 350 UK participants recruited via Prolific Academic. A three-player sequential (leader-follower) public goods game is used to represent the social dilemma and gender differences in behavior related to the role of gender beliefs and the gender group composition are examined to investigate whether male or female leaders are better cooperative role models under free-riding incentives and thus more successful in crowding in.

6. 5. Distributional Dynamics of Fama-French Factors in European Markets

   University essay from KTH/Matematisk statistik

   Author : Wilmer Löfgren; [2020]
   Keywords : Fama-French factors; NGARCH; Copula; Value-at-Risk; Risk model evaluation; Fama-French-faktorer; NGARCH; Copula; Value-at-Risk; Utvärdering av riskmodeller;

   Abstract : The three-factor model of Fama and French has proved to be a seminal contribution to asset pricing theory, and was recently extended to include two more factors, yielding the Fama-French five-factor model. Other proposed augmentations of the three-factor model includes the introduction of a momentum factor by Carthart. READ MORE
