  2. 1. Chain Graphs : Interpretations, Expressiveness and Learning Algorithms

    Author : Dag Sonntag; M. Jose Peña; Nahid Shahmehri; Jirka Vomlel; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chain Graphs; Probabilitstic Grapical Models;

    Abstract : Probabilistic graphical models are currently one of the most commonly used architectures for modelling and reasoning with uncertainty. The most widely used subclass of these models is directed acyclic graphs, also known as Bayesian networks, which are used in a wide range of applications both in research and industry. READ MORE

  4. 2. A Study of Chain Graph Interpretations

    Author : Dag Sonntag; Jose M. Peña; Nahid Shahmehri; Jirka Vomlel; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Probabilistic graphical models are today one of the most well used architectures for modelling and reasoning about knowledge with uncertainty. The most widely used subclass of these models is Bayesian networks that has found a wide range of applications both in industry and research. READ MORE

  5. 3. On Aspects of Anyons and Quantum Graphs

    Author : Babak Majidzadeh Garjani; Eddy Ardonne; Andrea Cappelli; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : This thesis consists of two distinct parts. The first part, based on the first two accompanied papers, is in the field of topological phases of matter and the second part, based on the third accompanied paper, looks at a problem in the field of quantum graphs, a rapidly growing field of mathematical physics.

  6. 4. Essays on Bayesian Inference for Social Networks

    Author : Johan Koskinen; Ove Frank; Philippa Pattison; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian inference; social network analysis; Markov chain Monte Carlo; exponential random graphs; cognitive social structures; longitudinal social networks.; Statistics; Statistik;

    Abstract : This thesis presents Bayesian solutions to inference problems for three types of social network data structures: a single observation of a social network, repeated observations on the same social network, and repeated observations on a social network developing through time.A social network is conceived as being a structure consisting of actors and their social interaction with each other.

  7. 5. Split Trees, Cuttings and Explosions

    Author : Cecilia Holmgren; Svante Janson; Luc Devroye; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Random Graphs; Random Trees; Split Trees; Renewal Theory; Binary Search Trees; Cuttings; Records; Tree Algorithms; Markov Chains; Galton-Watson Processes; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Abstract : This thesis is based on four papers investigating properties of split trees and also introducing new methods for studying such trees. Split trees comprise a large class of random trees of logarithmic height and include e.g., binary search trees, m-ary search trees, quadtrees, median of (2k+1)-trees, simplex trees, tries and digital search trees.
