    • Adaptive mixture methods based on Bregman divergences 

      Donmez, M. A.; Inan, H. A.; Kozat, S. S. (Elsevier, 2013)
      We investigate adaptive mixture methods that linearly combine outputs of m constituent filters running in parallel to model a desired signal. We use Bregman divergences and obtain certain multiplicative updates to train ...
    • A bound on the zero-error list coding capacity 

      Arıkan, Erdal (IEEE, 1993)
      We present a new bound on the zero-error list coding capacity, and using which, show that the list-of-3 capacity of the 4/3 channel is at most 6/19 bits, improving the best previously known bound of 3/8. The relation of ...
    • Entropi fonsiyonuna dayalı uyarlanır karar tümleştirme yapısı 

      Günay, Osman; Töreyin, B. U.; Köse, Kıvanç; Çetin, A. Enis (2012-04)
      Bu bildiride, resim analizi ve bilgisayarla görü uygulamalarında kullanılmak üzere entropi fonksiyonuna dayanan uyarlanır karar tümleştirme yapısı geliştirilmiştir. Bu yapıda bileşik algoritma, herbiri güven derecesini ...
    • Entropy minimization based robust algorithm for adaptive networks 

      Köse, Kıvanç; Çetin, A. Enis; Gunay O. (IEEE, 2012)
      In this paper, the problem of estimating the impulse responses of individual nodes in a network of nodes is dealt. It was shown by the previous work in literature that when the nodes can interact with each other, fusion ...
    • Entropy, invertibility and variational calculus of adapted shifts on Wiener space 

      Üstünel, A.S. (2009)
      In this work we study the necessary and sufficient conditions for a positive random variable whose expectation under the Wiener measure is one, to be represented as the Radon-Nikodym derivative of the image of the Wiener ...
    • An inequality on guessing and its application to sequential decoding 

      Arikan, E. (Institute of Electrical and Electronics Engineers, 1996-01)
      Let (X,Y) be a pair of discrete random variables with X taking one of M possible values, Suppose the value of X is to be determined, given the value of Y, by asking questions of the form "Is X equal to x?" until the answer ...
    • An information-theoretic analysis of Grover's algorithm 

      Arıkan, Erdal (IEEE, 2003-06-07)
      Grover discovered a quantum algorithm for identifying a target element in an unstructured search universe of N items in approximately 1r/4VN queries to a quantum oracle. For classical search using a classical oracle, the ...
    • Interpretation of the space-bandwidth product as the entropy of distinct connection patterns in multifacet optical interconnection architectures 

      Haldun M. Özaktaş; Brenner, K. -H.; Lohmann, A. W. (Optical Society of America, 1993)
      We show that the entropy of the distinct connection patterns that are possible with multifacet optical interconnection architectures is approximately equal to the space-bandwidth product of the optical system.
    • Martingale representation for degenerate diffusions 

      Üstünel, Ali Süleyman (Elsevier, 2019)
      Let $(W,H,\mu )$ be the classical Wiener space on ${\rm IR}^{d}$. Assume that $X=(X_{t})$ is a diffusion process satisfying the stochastic differential equation $dX_{t}=\sigma (t,X)dB_{t}+b(t,X)dt$, where $\sigma :[0,1]{\rm ...
    • A note on polarization martingales 

      Arıkan, Erdal (IEEE, 2014)
      Polarization results rely on martingales of mutual information and entropy functions. In this note an alternative formulation is considered where martingales are constructed on sample functions of the entropy function.
    • Trapped interacting Bose gas in nonextensive statistical mechanics 

      Tanatar, Bilal (The American Physical Society, 2002)
      We study the Bose-Einstein condensation (BEC) phenomenon in an interacting trapped Bose gas using the semiclassical two-fluid model and nonextensive statistical mechanics. The effects of nonextensivity characterized by a ...
