1. Variational AutoEncoders and Differential Privacy : balancing data synthesis and privacy constraints
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This thesis investigates the effectiveness of Tabular Variational Auto Encoders (TVAEs) in generating high-quality synthetic tabular data and assesses their compliance with differential privacy principles. The study shows that while TVAEs are better than VAEs at generating synthetic data that faithfully reproduces the distribution of real data as measured by the Synthetic Data Vault (SDV) metrics, the latter does not guarantee that the synthetic data is up to the task in practical industrial applications.

2. Regularizing Vision-Transformers Using Gumbel-Softmax Distributions on Echocardiography Data
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This thesis introduces an novel approach to model regularization in Vision Transformers (ViTs), a category of deep learning models. It employs stochastic embedded feature selection within the context of echocardiography video analysis, specifically focusing on the EchoNet-Dynamic dataset. LÄS MER
3. Copula approach to fitting bivariate time series
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : We apply the GARCH-copula method to estimate Value at Risk (VaR) for European and Stockholm stock indices. First, marginal distributions are estimated by the ARMA-GARCH model with normal, Student-t, and skewed t distributions. LÄS MER
4. Regional Regression Models of Mean Annual Streamflow and Design Flow in a Tropical Region of Colombia.
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : A responsible and sustainable water resources management is important. It is also crucial to take the presence of watercourses into account during design of hydraulic structures such as small dams and bridges. Doing this requires knowledge of estimates of annual streamflow and extreme flows to be used for design purposes. LÄS MER
5. An Extreme Value Approach To Pricing Credit Risk
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : An Extreme Value Approach To Pricing Credit Risk will outline the possibility to investigate a company’s price of risk over different time periods given a pre-defined risk level. With help of credit default swap (CDS) prices and extreme value theory the credit risk can be estimated for different return levels. LÄS MER
