1. 1. Bayesian inference methods for parameter estimation : Implementation and benchmarking

   University essay from Umeå universitet/Institutionen för datavetenskap

   Author : Sebastian Johansson; [2023]
   Keywords : ;

   Abstract : 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.

3. 2. Enhancement-basedSmall TargetDetection for InfraredImages

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

   Author : Yang Hanqi; [2023]
   Keywords : Infrared Images; Small targets; Dilated Convolution; Infraröda bilder; Små mål; Dilaterad konvolution;

   Abstract : 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. READ MORE

   Abstract : 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. READ MORE

5. 4. Know the flow - spatial and temporal variation of DOC exports and the importance of monitoring site specific discharge

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Johannes Larson; [2018]
   Keywords : dissolved organic carbon; DOC; export; boreal; specific discharge; spatiotemporal variation; löst organiskt kol; DOC; export; boreal; specifik avrinning; spatiotemporal variabilitet;

   Abstract : 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. READ MORE

6. 5. Bayesian inference in aggregated hidden Markov models

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Emil Marklund; [2015]
   Keywords : Bayesian inference; aggregated hidden Markov models; model selection; variational Bayes; nested sampling; single molecule data;

   Abstract : 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. READ MORE
