2. 21. Information-Theoretic Generalization Bounds: Tightness and Expressiveness

   Author : Fredrik Hellström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; information theory; neural networks; generalization; statistical learning; meta learning; PAC-Bayes; Machine learning;

   Abstract : Machine learning has achieved impressive feats in numerous domains, largely driven by the emergence of deep neural networks. Due to the high complexity of these models, classical bounds on the generalization error---that is, the difference between training and test performance---fail to explain this success. READ MORE

4. 22. Towards Automated Support for the Co-Evolution of Meta-Models and Grammars

   Author : Weixing Zhang; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blended Modeling; Co-Evolution; Systematic Literature Review; Grammar Optimization; Xtext; Blended Modeling; Systematic Literature Review; Xtext; Grammar Optimization; Co-Evolution;

   Abstract : Blended modeling is an emerging paradigm involving seamless interaction between multiple notations for the same underlying modeling language. We focus on a model-driven engineering (MDE) approach based on meta-models to develop textual languages to improve the blended modeling capabilities of modeling tools. READ MORE

5. 23. Managing virtual factory artifacts in extended product lifecycle management systems

   Author : Iman Morshedzadeh; Amos H. C. Ng; Masood Fathi; Kaveh Amouzgar; Dag Henrik Bergsjö; Högskolan i Skövde; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Virtual models; product lifecycle management; information model; knowledge management; ontology; manufacturing data; provenance; manufacturing systems; Production and Automation Engineering; Produktion och automatiseringsteknik;

   Abstract : Reusing previously designed virtual models and the knowledge extracted from running them can reduce time and costs. Since these models are representations of physical artifacts, they have been built based on some criteria, assumptions, and limitations. READ MORE

6. 24. Optimal strategies and information in foraging theory

   Author : Emma Sernland; Högskolan i Skövde; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian foraging; information use; public information; prior information; negative binomial distribution; group foraging; decision-making; information updating; leaving strategy; Ecology; Ekologi; NATURAL SCIENCES; NATURVETENSKAP; Other biology; Övrig biologi; Naturvetenskap; Natural sciences; information use; Bayesian foraging; public information; prior information; negative binomial distribution; group foraging; decision-making; information updating; leaving strategy; Ecology; Ekologi;

   Abstract : In this thesis, I present both theoretical and empirical work where we have studied how humans and animals use information in situations where they need to continually update their information on the density of a resource. We have found that the amount of information, and the way the information is presented, are important factors for how well decisions are adapted to current circumstances. READ MORE

7. 25. Information infrastructure risk : perspectives, practices & technologies

   Author : Lars Öbrand; Jonny Holmström; Ole Hanseth; Mari-Klara Stein; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Risk; risk management; practice research; information infrastructure theory;

   Abstract : This dissertation investigates the nature and management of information infrastructure risks in organizations. Specifically, it examines how practitioners identify and manage threats towards their organizational aims, and suggests ways of achieving sustainable risk management, in settings characterized by the integration of information technology (IT) and organizational processes.
