    • Adaptive decision fusion based cooperative spectrum sensing for cognitive radio systems 

      Töreyin, B. U.; Yarkan, S.; Qaraqe, K. A.; Çetin, Ahmet Enis (IEEE, 2011)
      In this paper, an online Adaptive Decision Fusion (ADF) framework is proposed for the central spectrum awareness engine of a spectrum sensor network in Cognitive Radio (CR) systems. Online learning approaches are powerful ...
    • Big-data streaming applications scheduling based on staged multi-armed bandits 

      Kanoun, K.; Tekin, C.; Atienza, D.; Van Der Schaar, M. (Institute of Electrical and Electronics Engineers, 2016)
      Several techniques have been recently proposed to adapt Big-Data streaming applications to existing many core platforms. Among these techniques, online reinforcement learning methods have been proposed that learn how to ...
    • A comparison of epidemic algorithms in wireless sensor networks 

      Akdere, M.; Bilgin, C. C.; Gerdaneri, O.; Korpeoglu, I.; Ulusoy, O.; Çetintemel, U. (Elsevier BV, 2006-08-21)
      We consider the problem of reliable data dissemination in the context of wireless sensor networks. For some application scenarios, reliable data dissemination to all nodes is necessary for propagating code updates, queries, ...
    • Cryptographic solutions for genomic privacy 

      Ayday, Erman (Springer, 2016-02)
      With the help of rapidly developing technology, DNA sequencing is becoming less expensive. As a consequence, the research in genomics has gained speed in paving the way to personalized (genomic) medicine, and geneticists ...
    • Discriminative fine-grained mixing for adaptive compression of data streams 

      Gedik, B. (Institute of Electrical and Electronics Engineers, 2014)
      This paper introduces an adaptive compression algorithm for transfer of data streams across operators in stream processing systems. The algorithm is adaptive in the sense that it can adjust the amount of compression applied ...
    • An efficient virtual topology design and traffic engineering scheme for IP/WDM networks 

      Şengezer, Namık; Karasan, Ezhan (Springer, 2007)
      We propose an online traffic engineering (TE) scheme for efficient routing of bandwidth guaranteed connections on a Multiprotocol label switching (MPLS)/wavelength division multiplexing (WDM) network with a traffic pattern ...
    • An online adaptive cooperation scheme for spectrum sensing based on a second-order statistical method 

      Yarkan S.; Töreyin, B. U.; Qaraqe, K. A.; Çetin, A. E. (Institute of Electrical and Electronics Engineers, 2012)
      Spectrum sensing is one of the most important features of cognitive radio (CR) systems. Although spectrum sensing can be performed by a single CR, it is shown in the literature that cooperative techniques, including multiple ...
    • Online bicriteria load balancing for distributed file servers 

      Tse, Savio (IEEE, 2008-08)
      We study the online bicriteria load balancing problem in a system of M distributed homogeneous file servers located in a cluster. The load and storage space are assumed to be independent. We propose two online approximate ...
    • An Online Causal Inference Framework for Modeling and Designing Systems Involving User Preferences: A State-Space Approach 

      Delibalta, I.; Baruh, L.; Kozat, S. S. (Hindawi Limited, 2017)
      We provide a causal inference framework to model the effects of machine learning algorithms on user preferences. We then use this mathematical model to prove that the overall system can be tuned to alter those preferences ...
    • Online detection of fire in video 

      Töreyin, Behçet Uğur; Çetin, Ahmet Enis (IEEE, 2007)
      This paper describes an online learning based method to detect flames in video by processing the data generated by an ordinary camera monitoring a scene. Our fire detection method consists of weak classifiers based on ...
    • Online exercise ECG signal orthogonalization 

      Acar, B.; Köymen H. (1996)
      In this paper an efficient method of making use of the redundancy in standard 12 lead ECG signals to eliminate noise is described. The method is based on orthogonalization via online Singular Value Decomposition (SVD). Its ...
    • Online solutions for scalable file server systems 

      Tse, Savio S. H. (ACM, 2006)
      We propose three online algorithms for scalable file server systems. A scalable file server is expected to provide rather stable services while the numbers of users, tasks, and data volumes keep increasing. One of the ...
