  • Algebraic break of image ciphers based on discretized chaotic map lattices 

    Solak, Ercan; Çokal, Cahit (ELSEVIER SCIENCE INC, 2011-01)
    In this paper, we provide an algebraic cryptanalysis of a recently proposed chaotic image cipher. We show that the secret parameters of the algorithm can be revealed using chosen-plaintext attacks. Our attack uses the orbit ...
  • Design and analysis of classifier learning experiments in bioinformatics: survey and case studies 

    İrsoy, Ozan; Yıldız, Olcay Taner; Alpaydın, Ahmet İbrahim Ethem (IEEE COMPUTER SOC, 2012-12)
    In many bioinformatics applications, it is important to assess and compare the performances of algorithms trained from data, to be able to draw conclusions unaffected by chance and are therefore significant. Both the design ...
  • Eigenclassifiers for combining correlated classifiers 

    Ulaş, Aydın; Yıldız, Olcay Taner; Alpaydın, Ahmet İbrahim Ethem (ELSEVIER SCIENCE INC, 2012-03-15)
    In practice, classifiers in an ensemble are not independent. This paper is the continuation of our previous work on ensemble subset selection [A. Ulas, M. Semerci, O.T. Yildiz, E. Alpaydin, Incremental construction of ...
  • Force-Directed Approaches to Sensor Localization 

    Efrat, Alon; Forrester, David; Iyer, Anand; Kobourov, Stephen G.; Erten, Cesim; Kılıç, Yasin Ozan (ASSOC COMPUTING MACHINERY, 2010-09)
    As the number of applications of sensor networks increases, so does the interest in sensor network localization, that is, in recovering the correct position of each node in a network of sensors from partial connectivity ...
