• Biological-inspired algorithms for dynamic search in web graphs 

      Kouzas, G.; Anagnostopoulos, I. (2011)
      We propose a biological-inspired algorithmic procedure for improving the precision level in respect to a web user's query. This algorithm is capable of tracing relevant information in web graphs, imitating the mission of ...
    • A hybrid classification algorithm evaluated on medical data 

      Michelakos, I.; Papageorgiou, E.; Vasilakopoulos, M. (2010)
      Ant colony optimization algorithms have been applied successfully to data mining classification problems. Recently, an improved version of cAnt-Miner (Ant-Miner coping with continuous attributes), called cAnt-Miner2, has ...
    • A study of cAnt-Miner2 parameters using medical data sets 

      Michelakos, I.; Papageorgiou, E. I.; Vasilakopoulos, M. (2010)
      This paper presents a study of the user-defined parameters of the cAnt-Miner2 algorithm which extended the approach of coping with continuous attributes that was introduced by the cAnt-Miner algorithm. Experiments on two ...
