2. 1. Online engineering : On the nature of open computational systems

   Author : Martin Fredriksson; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Online Engineering; open computational systems;

   Abstract : Computing has evolved from isolated machines, providing calculative support of applications, toward communication networks that provide functional support to groups of people and embedded systems. Perhaps, one of the most compelling feature and benefit of computers is their overwhelming computing efficiency. READ MORE

4. 2. Online Communities and Learning for Health : The Use of Online Health Communities and Online Expertise for People with Established Bad Habits

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Health community; online community; learning; bad habits; conversation; speech acts; Ask the Expert system; holistic.; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

   Abstract : Patients as well as citizens are getting more and more empowered due to the use of the Internet. The last years have brought a new trend to the Internet, the virtual or online health communities, used by many people and for various purposes. READ MORE

5. 3. Approximation and Online Algorithms with Applications in Computational Biology and Computational Geometry

   Author : Mia Persson; Data Vetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; system; systems; control; Datalogi; numerical analysis; broadcasting; polygon exploration; robotics; Mathematics; Matematik; Computer science; clique partition; clustering; computational complexity; computational geometry; computational biology; online algorithm; kontroll; approximation algorithm;

   Abstract : The main contributions of this thesis are in the area of approximation and online algorithm design and derivation of lower bounds on the approximability for a number of combinatorial optimization problems with applications in computational biology and computational geometry. Approximation and online algorithms are fundamental tools used to deal with computationally hard problems and problems in which the input is gradually disclosed over time. READ MORE

6. 4. Online Dimensionality Reduction

   Author : Kaito Ariu; Alexandre Proutiere; Mikael Johansson; Richard Combes; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In this thesis, we investigate online dimensionality reduction methods, wherethe algorithms learn by sequentially acquiring data. We focus on two specificalgorithm design problems in (i) recommender systems and (ii) heterogeneousclustering from binary user feedback. READ MORE

7. 5. Online Learning for Energy Efficient Navigation in Stochastic Transport Networks

   Author : Niklas Åkerblom; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Thompson Sampling; Online Minimax Path Problem; Multi-Armed Bandits; Online Learning; Online Shortest Path Problem; Machine Learning; Combinatorial Semi-Bandits; Energy Efficient Navigation;

   Abstract : Reducing the dependence on fossil fuels in the transport sector is crucial to have a realistic chance of halting climate change. The automotive industry is, therefore, transitioning towards an electrified future at an unprecedented pace. READ MORE
