    • Ray representation for k-trees 

      Akman, V.; Franklin, Wm. R. (Elsevier, 1989)
      k-trees have established themselves as useful data structures in pattern recognition. A fundamental operation regarding k-trees is the construction of a k-tree. We present a method to store an object as a set of rays and ...
    • Re-identification of individuals in genomic data-sharing beacons via allele inference 

      Von Thenen, N.; Ayday, E.; Cicek, A. E. (Oxford University Press, 2019-02)
      Motivation: Genomic data-sharing beacons aim to provide a secure, easy to implement and standardized interface for data-sharing by only allowing yes/no queries on the presence of specific alleles in the dataset. Previously ...
    • Re-ranking of image search results using a graph algorithm 

      Sevil, S.; Zitouni H.; Ikizler, N.; Özkan, D.; Duygulu P. (2008)
      Although one of the most common usages of Internet is searching, especially in image search, the users are not satisfied due to many irrelevant results. In this paper we present a method to identify irrelevant results of ...
    • Re-ranking of web image search results using a graph algorithm 

      Zitouni, Hilal; Sevil, Sare; Özkan, Derya; Duygulu, Pınar (IEEE, 2008-12)
      We propose a method to improve the results of image search engines on the Internet to satisfy users who desire to see relevant images in the first few pages. The method re-ranks the results of text based systems by ...
    • Reactive footstep planning for a planar spring mass hopper 

      Arslan, Ömür; Saranlı, Uluç; Morgül, Ömer (IEEE, 2009-10)
