  • Theme supervised nonnegative matrix factorization for topic modeling 
    Suyunu, Burak. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2020., 2020.)
    Topic models are often used to organize and interpret large and unstructured corpora of text documents. They try to explain the topics that constitute the semantic infrastructure of the document sets and try to find the ...
  • Thread vulnerability for multicore architectures 
    Öz, Işıl. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    Continuously reducing transistor sizes and aggressive low power operating modes employed by modern architectures tend to increase transient error rates. A metric of reliability is required in order to evaluate approaches ...
  • Three dimensional face recognition 
    Gökberk, Berk. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    In this thesis, we attack the problem of identifying humans from their three dimensional facial characteristics. For this purpose, a complete 3D face recognition system is developed. We divide the whole system into ...
  • Three dimensional face recognition under occlusion variance 
    Alyüz, Neşe. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    With advances in sensor technology, three dimensional (3D) face has become an emerging biometric modality, preferred especially in high security applications. However, dealing with occlusions covering the facial surface ...
