T2 Bayesian Networks and Trust Fusion with Subjective Logic Length: 3 hours (half day) Intended Audience: This tutorial is targeted at researchers, system designers and developers working in industry and academia in the following areas Information fusion in general, Bayesian networks Machine learning, Computational trust AI in general Decision support tools No prerequisite knowledge other than basic probability calculus and discrete mathematics is required. Description: This tutorial gives attendees a first-hand insight into the theory and application of subjective logic by the author and researcher who proposed and started developing this framework in 1997. This tutorial gives an introduction to subjective logic, and how it applies to Bayesian network modelling and information fusion. Specific elements of the tutorial are: 1. Representation and interpretation of subjective opinions a. Formal representation of binomial, multinomial and hyper opinions b. Correspondence between subjective opinions and other relevant representations of trust such as binary logic propositions, probabilities, Dempster-Shafer belief functions, c. Expressing opinions as PDFs (probability density functions) and fuzzy verbal categories 2. Algebraic operators of subjective logic a. Operators for binomial opinions: transitivity, fusion, product, coproduct b. Operators for multinomial opinions: conditional deduction and abduction, fusion 3. Applications of subjective logic a. Bayesian network modelling and analysis b. Trust networks modelling and analysis of c. Subjective networks, combining Bayesian and trust networks Presentation slides will be handed out to participants. New book on subjective logic (2016 edition) will be offered at special price to tutorial participants. Prerequisites: Presenter: Audun Jøsang Dr. Audun Jøsang, Professor at the at the University of Oslo, Norway, and Adjunct Professor at Queensland University of Technology, Australia. Prof. Jøsang is the author of subjective logic which is being applied worldwide by researchers and practitioners in the areas of fusion, uncertainty reasoning, as well as trust and reputation systems. Before joining Oslo University in 2008, Prof. Jøsang worked as Associate Professor at QUT and research leader for cybersecurity at DSTC in Australia, system design engineer at Alcatel Telecom in Belgium and research scientist at Telenor in Norway. Prof. Jøsang has a Master's in Information Security from Royal Holloway College, University of London, and a PhD from NTNU in Norway. Back to Tutorials
