1. Bayesian inference methods for parameter estimation : Implementation and benchmarking
Master-uppsats, Umeå universitet/Institutionen för datavetenskapSammanfattning : In this study, three implementations of the nested sampling algorithm have been implemented, in the programming language Rust, compared and benchmarked. These variations consist of a classic version, closely resembling the first appearance of the algorithm, a version that produces samples from a single ellipsoid, and a version tha tuses multiple ellipsoids to generate its samples.

2. Enhancement-basedSmall TargetDetection for InfraredImages
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Infrared small target detection is widely used in fields such as military and security. UNet, which is a classical semantic segmentation method proposed in 2015, has shown excellent performance and robustness. However, U-Net suffers from the problem of losing small targets in deep layers after multiple down-sampling operations. LÄS MER
3. Towards Dialogue Models for Online Grooming Detection
Kandidat-uppsats, Umeå universitet/Institutionen för psykologiSammanfattning : Social networks are a popular way for people to engage in activities and find new friends over the Internet. One central feature that these services share is the possibility for users to interact and share personal information. LÄS MER
4. Know the flow - spatial and temporal variation of DOC exports and the importance of monitoring site specific discharge
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : The export of dissolved organic carbon (DOC) is an important component in both water quality and carbon cycling within boreal catchments. DOC exports are mainly controlled by discharge. LÄS MER
5. Bayesian inference in aggregated hidden Markov models
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Single molecule experiments study the kinetics of molecular biological systems. Many such studies generate data that can be described by aggregated hidden Markov models, whereby there is a need of doing inference on such data and models. LÄS MER
