  4. 2. Continuous time Graphical Models and Decomposition Sampling

    Author : Jonas Hallgren; Timo Koski; Blazej Miasojedow; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Two topics in temporal graphical probabilistic models are studied. The topics are treated in separate papers, both with applications in finance. The first paper study inference in dynamic Bayesian networks using Monte Carlo methods. A new method for sampling random variables is proposed. READ MORE

  5. 3. Scalable and Efficient Probabilistic Topic Model Inference for Textual Data

    Author : Måns Magnusson; Mattias Villani; Marco Kuhlmann; Jordan Boyd-Graber; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Text analysis; Bayesian inference; Markov chain Monte Carlo; topic models; Textanalys; Bayesiansk inferens; Markov chain Monte Carlo; temamodeller;

    Abstract : Probabilistic topic models have proven to be an extremely versatile class of mixed-membership models for discovering the thematic structure of text collections. There are many possible applications, covering a broad range of areas of study: technology, natural science, social science and the humanities. READ MORE

  6. 4. Graphical representations of Ising and Potts models : Stochastic geometry of the quantum Ising model and the space-time Potts model

    Author : Jakob Erik Björnberg; Anders Björner; Jeffrey Steif; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Ising model; Ising model; Potts model; random-cluster model; random-current representation; random-parity representation; differential inequality; phase transition; Discrete mathematics; Diskret matematik;

    Abstract : HTML clipboard Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as external conditions are varied. READ MORE

  7. 5. Development of Risk Oriented Accident Analysis Methodology for Assessment of Effectiveness of Severe Accident Management Strategy in Nordic BWR

    Author : Sergey Galushin; Pavel Kudinov; Harri Tuomisto; KTH; []
    Keywords : Severe accident management; sensitivity; uncertainty; MELCOR; ROAAM; Svår haverihantering; känslighet och osäkerhetsanalys; MELCOR; ROAAM; Fysik; Physics;

    Abstract : Nordic Boiling Water Reactor (BWR) design employs ex-vessel debris coolability as a severe accident management strategy (SAM). In case of a severe accident, the debris ejected from the vessel are expected to fragment, quench and form a debris bed, which is coolable by a natural circulation of water. READ MORE
