    Abstract : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. READ MORE

  5. 13. Inference in a Partially Observed Percolation Process

    Author : Oscar Hammar; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Percolation; Bayesian inference; frequentistic inference; consistency; Markov chain Monte Carlo; Monte Carlo Expectation Maximization; Markov chain Monte Carlo;

    Abstract : In this licentiate thesis, inference in a partially oberved percolation process living on a graph, is considered. Each edge of the graph is declared open with probability $\theta$ and closed with probability $1-\theta$ independently of the states of all other edges. READ MORE

  6. 14. The role of Corporate Responsibility disclosure – For managing external expectation and pressure

    Author : Marina Grahovar; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; External expectations and pressures; Disclosure; Corporate social responsibility disclosure; News coverage; Energy industry;

    Abstract : Society acknowledges that companies’ operations have an effect on their business environment. As a result, companies are not only responsible for maximization of shareholder value, but also for the impact of their environmental and social policies. READ MORE

  7. 15. On particle-based online smoothing and parameter inference in general hidden Markov models

    Author : Johan Westerborn; Jimmy Olsson; Thomas Schön; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of two papers studying online inference in general hidden Markov models using sequential Monte Carlo methods.The first paper present an novel algorithm, the particle-based, rapid incremental smoother (PaRIS), aimed at efficiently perform online approximation of smoothed expectations of additive state functionals in general hidden Markov models.
