      Clustering subjects in genetic studies with self organizing maps 

      Aristodimou, Aristos; Antoniades, Athos; Pattichis, Constantinos S. (2012)
      Several machine learning techniques have been applied for finding multi-loci associations among Single Nucleotide Polymorphisms (SNPs) and a disease. In this paper it is investigated whether Self Organizing Maps (SOMs) can ...

      A comparative study on filtering protein secondary structure prediction 

      Kountouris, P.; Agathocleous, Michalis; Promponas, Vasilis J.; Christodoulou, Georgia; Hadjicostas, S.; Vassiliades, Vassilis; Christodoulou, Chris C. (2012)
      Filtering of Protein Secondary Structure Prediction (PSSP) aims to provide physicochemically realistic results, while it usually improves the predictive performance. We performed a comparative study on this challenging ...

      First Trimester Noninvasive Prenatal Diagnosis: A Computational Intelligence Approach 

      Neocleous, Andreas C.; Nicolaides, Kypros H.; Schizas, Christos N. (2016)
      The objective of this study is to examine the potential value of using machine learning techniques such as artificial neural network (ANN) schemes for the noninvasive estimation, at 11-13 weeks of gestation, the risk for ...

      A probabilistic reasoning approach for discovering web crawler sessions 

      Stassopoulou, Athena; Dikaiakos, Marios D. (2007)
      In this paper we introduce a probabilistic-reasoning approach to detect Web robots (crawlers) from human visitors of Web sites. Our approach employs a Naive Bayes network to classify the HTTP sessions of a Web-server access ...

      Real-time web crawler detection 

      Balla, A.; Stassopoulou, Athena; Dikaiakos, Marios D. (2011)
      In this paper we present a methodology for detecting web crawlers in real time. We use decision trees to classify requests in real time, as originating from a crawler or human, while their session is ongoing. For this ...

      Web robot detection: A probabilistic reasoning approach 

      Stassopoulou, Athena; Dikaiakos, Marios D. (2009)
      In this paper, we introduce a probabilistic modeling approach for addressing the problem of Web robot detection from Web-server access logs. More specifically, we construct a Bayesian network that classifies automatically ...
