    • Compression of images in CFA format 

      Cüce, Halil İbrahim; Çetin, A. Enis; Davey, M. K. (IEEE, 2006)
      In this paper, images in Color Filter Array (CFA) format are compressed without converting them to full-RGB color images. Green pixels are extracted from the CFA image data and placed in a rectangular array, and compressed ...

    • CRLB based optimal noise enhanced parameter estimation using quantized observations 

      Balkan, G. O.; Gezici, Sinan (IEEE, 2010-02-22)
      In this letter, optimal additive noise is characterized for parameter estimation based on quantized observations. First, optimal probability distribution of noise that should be added to observations is formulated in terms ...

    • The design of finite-state machines for quantization using simulated annealing 

      Kuruoğlu, Ercan Engin; Ayanoğlu, E. (IEEE, 1993)
      In this paper, the combinatorial optimization algorithm known as simulated annealing is used for the optimization of the trellis structure or the next-state map of the decoder finite-state machine in trellis waveform coding. ...

    • Noise enhanced parameter estimation using quantized observations 

      Balkan, Gökçe Osman (Bilkent University, 2010)
      In this thesis, optimal additive noise is characterized for both single and multiple parameter estimation based on quantized observations. In both cases, first, optimal probability distribution of noise that should be added ...

    • Quadratic multi-dimensional signaling games and affine equilibria 

      Sarıtaş, S.; Yüksel S.; Gezici, Sinan (Institute of Electrical and Electronics Engineers Inc., 2017)
      This paper studies the decentralized quadratic cheap talk and signaling game problems when an encoder and a decoder, viewed as two decision makers, have misaligned objective functions. The main contributions of this study ...

    • Signaling and information games with subjective costs or priors and privacy constraints 

      Kazıklı, Ertan (Bilkent University, 2021-08)
      We investigate signaling game problems where an encoder and a decoder with misaligned objectives communicate. We consider a variety of setups involving cost criterion mismatch, prior mismatch and a particular application ...

    • Signaling games in networked systems 

      Sarıtaş, Serkan (Bilkent University, 2018-07)
      We investigate decentralized quadratic cheap talk and signaling game problems when the decision makers (an encoder and a decoder) have misaligned objective functions. We first extend the classical results of Crawford and ...

    • Simulation-based engineering 

      Çakmakcı, Melih; Sendur, G. K.; Durak, U. (Springer, 2017)
      Engineers, mathematicians, and scientists were always interested in numerical solutions of real-world problems. The ultimate objective within nearly all engineering projects is to reach a functional design without violating ...

    • Super-resolution using multiple quantized images 

      Özçelikkale, Ayça; Akar, G. B.; Özaktas, Haldun M. (IEEE, 2010)
      In this paper, we study the effect of limited amplitude resolution (pixel depth) in super-resolution problem. The problem we address differs from the standard super-resolution problem in that amplitude resolution is ...

    • Terabits-per-second throughput for polar codes 

      Süral, Altuğ; Sezer, E. Göksu; Ertuğrul, Yiğit; Arıkan, Orhan; Arıkan, Erdal (IEEE, 2019-09)
      By using Majority Logic (MJL) aided Successive Cancellation (SC) decoding algorithm, an architecture and a specific implementation for high throughput polar coding are proposed. SC-MJL algorithm exploits the low complexity ...

    • Understanding how orthogonality of parameters improves quantization of neural networks 

      Eryılmaz, Şükrü Burç; Dündar, Ayşegül (IEEE, 2022-05-10)
      We analyze why the orthogonality penalty improves quantization in deep neural networks. Using results from perturbation theory as well as through extensive experiments with Resnet50, Resnet101, and VGG19 models, we ...
