    • Application of machine learning in tissue characterization 

      Kvam, Johannes (Doctoral theses at NTNU;2019:119, Doctoral thesis, 2019)
      Bruk av maskinlæring i karakterisering av vev Karakterisering av vev handler om å skille ulike vevstyper basert på en eller annen egenskap som vevet innehar. Innen medisin har ofte sykt og friskt vev ulike fysiske egenskaper. ...

    • Applying Transfer Learning to Traffic Surveillance Videos for Accident Detection 

      Pathak, Ajeet Ram; Elster, Anne Cathrine (Chapter, 2022)

    • Auto-tunable GPU BLAS 

      Lien, Geir Josten (Master thesis, 2012)
      In this paper, we present our implementation of an Auto tuning system, written in C++, which incorporate the use of OpenCL kernels. We deploy this approach on different GPU architectures, evaluating the performance of the ...

    • Auto-tunable GPU BLAS 

      Steinsland, Jarle Erdal (Master thesis, 2011)
      OpenCL is fast becoming the preferred framework used to make programs for heterogeneous platforms consisting of at least one CPU and one or more accelerators. The GPU being readily available in almost all computers, it is ...

    • Automate Detection and Weight Estimation of Fish in Underwater 3D Images 

      Nystad, Lars-Håkon Nohr (Master thesis, 2018)
      Being able to determine the weight of fish is important information for fish breeding facilities. Current methods rely on manual measurements, but it is interesting to look into how underwater imaging can be used to automate ...

    • Automatic Optimization of MPI Applications - Turning Synchronous Calls Into Asynchronous 

      Natvig, Thorvald (Master thesis, 2006)
      The availability of cheap computers with outstanding single-processor performance coupled with Ethernet and the development of open MPI implementations has led to a drastic increase in the number of HPC clusters. This, in ...
