  1. 1. Evaluation of Probabilistic Programming Frameworks

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Carl Munkby; [2022]
    Keywords : Computational statistics; Bayesian statistics; Probabilistic programming; Probabilistic modelling; Stan; TensorFlow Probability; Pyro; NumPyro; Markov Chain Monte Carlo; Hamiltonian Monte Carlo; NUTS;

    Abstract : In recent years significant progress has been made in the area of Probabilistic Programming, contributing to a considerably easier workflow for quantitative research in many fields. However, as new Probabilistic Programming Frameworks (PPFs) are continuously being created and developed, there is a need for finding ways of evaluating and benchmarking these frameworks. READ MORE

  3. 2. Efficient Sampling of Gaussian Processes under Linear Inequality Constraints

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Bayu Beta Brahmantio; [2021]
    Keywords : Gaussian process; truncated multivariate Gaussian; Hamiltonian Monte Carlo; Elliptical Slice Sampling;

    Abstract : In this thesis, newer Markov Chain Monte Carlo (MCMC) algorithms are implemented and compared in terms of their efficiency in the context of sampling from Gaussian processes under linear inequality constraints. Extending the framework of Gaussian process that uses Gibbs sampler, two MCMC algorithms, Exact Hamiltonian Monte Carlo (HMC) and Analytic Elliptical Slice Sampling (ESS), are used to sample values of truncated multivariate Gaussian distributions that are used for Gaussian process regression models with linear inequality constraints.

  4. 3. An in vitro Study of Drug-induced Degranulation of Human HMC-1 Mast Cells and Rat RBL-2H3 Cells

    University essay from Umeå universitet/Tandläkarutbildning

    Author : Ava Tahmasebi; Jennifer Skytén; [2014]
    Keywords : ;

    Abstract : Mast cells and basophils participate in biological responses such as inflammation and allergic reactions and contain potent mediators such as histamine and cytokines. Some drugs, for example opioids, are known to trigger mast cell degranulation with the release of immunogenic mediators that may cause severe side effects. READ MORE

  5. 4. Lack of Lipopolysaccharide-induced β-hexosaminidase and TNF-α Release from Human Mast Cells (HMC-1) and Rat Basophilic Cells (RBL-2H3)

    University essay from Umeå universitet/Tandläkarutbildning

    Author : Madeleine Malmbom; Hanna Svahn; [2014]
    Keywords : ;

    Abstract : Mast cells are important immune cells that are able to degranulate potent mediators, and participate in infections and inflammatory responses. The process of mast cell degranulation is complex and still partly unknown, especially in bacterial infections caused by endotoxins such as lipopolysaccarides. READ MORE

  6. 5. From Set Top Box to Home Media Center

    University essay from KTH/Radio Systems Laboratory (RS Lab)

    Author : Yi Fu; Ruimin Li; [2014]
    Keywords : Multimedia; HMC; STB; Prototype; Roadmap; IPTV; Ultra HD; Multimedia; HMC; Digitalboxar; Prototyp; Färdplan; IPTV; Ultra HD;

    Abstract : Although Set-top-Boxes(STBs) are widely deployed today to connect a media source to a display (traditionally a television set), the market is changing due to the introduction of Internet Protocol Television, Over-the-Top streaming devices, gaming console, home theater Personal Computer, smart TV, etc. There is an evolving concept of a Home Media Center (HMC).
