    • Beyond the question of fixed-parameter tractability 

      Dregi, Markus Fanebust (The University of Bergen, 2017-01-06)
      Multivariate complexity is a prominent field that over the last decades has developed a rich toolbox, not only to tackle seemingly intractable problems, but also to describe the boundaries of tractability in a richer and ...

    • Precrec: fast and accurate precision-recall and ROC curve calculations in R 

      Saito, Takaya; Rehmsmeier, Marc (Oxford University Press, 2017)
      The precision–recall plot is more informative than the ROC plot when evaluating classifiers on imbalanced datasets, but fast and accurate curve calculation tools for precision–recall plots are currently not available. We ...

    • A model for optimal fleet composition of vessels for offshore wind farm maintenance 

      Gutierrez-Alcoba, Alejandro; Ortega, Gloria; Hendrix, Eligius M.T.; Halvorsen-Weare, Elin Espeland; Haugland, Dag (Elsevier, 2017)
      We present a discrete optimisation model that chooses an optimal fleet of vessels to support maintenance operations at Offshore Wind Farms (OFWs). The model is presented as a bi-level problem. On the first (tactical) level, ...

    • Community Detection on the GPU 

      Naim, Md.; Manne, Fredrik; Halappanavar, Mahantesh; Tumeo, Antonino (IEEE, 2017)
      We present and evaluate a new GPU algorithm based on the Louvain method for community detection. Our algorithm is the first for this problem that parallelizes the access to individual edges. In this way we can fine tune ...

    • A Comparative Study on Distributed Storage and Erasure Coding Techniques Using Apache Hadoop Over NorNet Core 

      Vela, Maximiliano Matias (The University of Bergen, 2017)
      Both private and public sector organizations are constantly looking for new ways to keep their information safe and accessible at all times. Over the past few decades, replication has always been a reliable way to make ...

    • Naive and adapted utilization of the GPU for general purpose computing 

      Mjøs, Alexander (The University of Bergen, 2017)
      In this thesis we will see that adaptive utilization of the graphical processing unit (GPU) has much better performance than naive utilization, but it takes longer time to implement and requires more knowledge about ...
      Master thesis
    • Towards a multilevel model transformation engine 

      Johnsen, Leif Arne Røyrøy (The University of Bergen, 2017)
      Domain specific modelling languages (DSML) are usually defined through fixed level meta modelling tools such as EMF. While this is sufficient for defining languages that has no overlap with other languages, the approach ...

    • Spiking Neural Networks for Pattern Recognition 

      Vestbøstad, Ketil Yddal (The University of Bergen, 2017)
      We have investigated an existing theoretical model for spiking neural networks, and based on this model we have implemented our own network. Then we have carried out experiments with this network, and compared its performance ...
