    • A Framework for Speech Recognition using Logistic Regression 

      Birkenes, Øystein (Doktoravhandlinger ved NTNU, 1503-8181; 2007:165, Doctoral thesis, 2007)
      Although discriminative approaches like the support vector machine or logistic regression have had great success in many pattern recognition application, they have only achieved limited success in speech recognition. Two ...

    • Frame based signal representation and compression 

      Engan, Kjersti (Dr. ingeniøravhandling, 0809-103X; 2000:65, Doctoral thesis, 2000)
      The demand for efficient communication and data storage is continuously increasing and signal representation and compression are important factors in digital communication and storage systems. This work deals with Frame ...

    • Rate-distortion optimal vector selection in frame based compression 

      Ryen, Tom (Doktoravhandlinger ved NTNU, 1503-8181; 2005:107, Doctoral thesis, 2005)
      In signal compression we distinguish between lossless and lossy compression. In lossless compression, the encoded signal is more bit efficient than the original signal and is exactly the same as the original one when ...

    • Signal analysis of out-of-hospital cardiac arrest electrocardiograms for decision support during cardiopulmonary resuscitation 

      Eftestøl, Trygve C. (Dr. ingeniøravhandling, 0809-103X; 2000:66, Doctoral thesis, 2000)
      This thesis focuses on signal analysis of electrocardiograms (ECG) from out-of-hospital cardiac arrested patients. The application of such methods may eventually contribute in guiding therapy towards improved survival rates ...
