  • Error propagation through generalized high dimensional model representation for data partitioning 

    Tunga, Mehmet Alper; Demiralp, Metin (WILEY-V C H VERLAG GMBH, 2004)
    In many circumstances the explicit form of a multivariate function is not known; rather a finite number of data is listed from some physical experiments. In such cases a function can be constructed only by imposing some ...
  • Design of real-time VBR traffic shaping schemes by considering the impact of both buffer overflows and deadline violations 

    Dağ, Tamer; Stavrakakis, Ioannis (INT INST INFORMATICS & SYSTEMICS, 2005)
    While smoothing the traffic of time sensitive applications at the user premises can reduce the losses due to buffer overflows within the network, it may have an adverse effect on the losses due to the deadline violations ...

    Karaman, Ayşe; Hassanein, Hossam (IEEE, 2005-10-03)
    The core-based approach in multipoint communication enhances the solution space in terms of QoS-efficiency of solutions in inter and intra-domain routing. In an earlier work [KH04], we showed that the constrained cost ...
  • A priority based packet scheduler with deadline considerations 

    Dağ, Tamer; Gökgöl, Oral (IEEE COMPUTER SOC, 2006)
    QoS issues have become a focal point of research on Next Generation Networks (NGNs). In order to supply the various QoS requirement for different kinds of applications, new scheduling policies need to be developed and ...
  • The modified Proactive feedback based flow control scheme for best-effort applications 

    Dağ, Tamer (INT INST INFORMATICS & SYSTEMICS, 2007)
    High speed networks that are characterized by large bandwidth propagation delay products are expected to support applications with diverse traffic characteristics and Quality of Service (QoS) requirements. Thus, flow control ...
  • Crossing minimization in weighted bipartite graphs 

    Çakıroğlu, Olca A.; Erten, Cesim; Karataş, Ömer; Sözdinler, Melih (SPRINGER-VERLAG BERLIN, 2007)
    Given a bipartite graph G = (L-0, L-1, E) and a fixed ordering of the nodes in L-0, the problem of finding an ordering of the nodes in L-1 that minimizes the number of crossings has received much attention in literature. ...
  • Driver Recognition Using Gaussian Mixture Models and Decision Fusion Techniques 

    Benli, Kristin Surpuhi; Düzağaç, Remzi; Eskil, Mustafa Taner (SPRINGER-VERLAG BERLIN, 2008)
    In this paper we present our research in driver recognition. The goal of this study is to investigate the performance of different classifier fusion techniques in a driver recognition scenario. We are using solely driving ...
  • A robust biclustering method based on crossing minimization in bipartite graphs 

    Erten, Cesim; Sözdinler, Melih (SPRINGER-VERLAG BERLIN, 2009)
  • A novel approach to morphological disambiguation for Turkish 

    Görgün, Onur; Yıldız, Olcay Taner (Springer-Verlag, 2011-09-26)
    In this paper, we propose a classification based approach to the morphological disambiguation for Turkish language. Due to complex morphology in Turkish, any word can get unlimited number of affixes resulting very large ...
  • Numerical integration methods for simulation of mass-spring-damper systems 

    Özgüz, Mete; Eskil, Murat Taner (Springer-Verlag, 2011-09-26)
    The dynamics of a face are often implemented as a system of connected particles with various forces acting upon them. Animation of such a system requires the approximation of velocity and position of each particle through ...
  • Palmprint verification using SIFT majority voting 

    Abeysundera, Hasith Pasindu; Eskil, Mustafa Taner (Springer-Verlag, 2011-09-26)
    In this paper we illustrate the implementation of a robust, real-time biometric system for identity verification based on palmprint images. The palmprint images are preprocessed to align the major axes of hand shapes and ...
  • Semi-automatic adaptation of high-polygon wireframe face models through inverse perspective projection 

    Benli, Kristin Surpuhi; Ağdoğan, Didem; Özgüz, Mete; Eskİl, Mustafa Taner (Springer-Verlag, 2011-09-26)
    Precise registration of a generic 3D face model with a subject's face is a critical stage for model based analysis of facial expressions. In this study we propose a semi-automatic model fitting algorithm to fit a high-polygon ...
  • Unsupervised morphological analysis using tries 

    Ak, Koray; Yıldız, Olcay Taner (Springer London, 2011-09-28)
    This article presents an unsupervised morphological analysis algorithm to segment words into roots and affixes. The algorithm relies on word occurrences in a given dataset. Target languages are English, Finnish, and Turkish, ...
  • Searching for the Optimal Ordering of Classes in Rule Induction 

    Ata, Sezin; Yıldız, Olcay Taner (IEEE, 2012)
    Rule induction algorithms such as Ripper, solve a K > 2 class problem by converting it into a sequence of K - 1 two-class problems. As a usual heuristic, the classes are fed into the algorithm in the order of increasing ...
