Research ArticleOpen accessAll words, across the recordAn Enhancement of Bayesian Inference Network for Ligand-Based Virtual Screening using Features SelectionAli Ahmed, Ammar Abdo, Naomie SalimProblem statement: Similarity based Virtual Screening (VS) deals with a large amount of data containing irrelevant and/or redundant fragments or features. Recent use of Bayesian network as an alternative for existing tools for similarity based VS has received noticeable attention of the researchers in the field of chemoinformatics. Approach: To this end, different models of Bayesian network have been developed. … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,724 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInvestigation of Quantitative Plant Activity Relationship (QPAR) for Diabetics II Using Genetic AlgorithmSimanta Kumar Nayak, Bikram Kesari Ratha, Payodhar Padhi et al.The present study demonstrates a novel computational approach for Indian Traditional Medicine (ITM) for the effective antidiabetic drug. Indian traditional practitioners are using many natural Herbals for the cure of diabetes. Though many diabetes patients are getting temporarily cured still its cause and effects are unknown due to lack of proper scientific investigation. Individual plant bioactivities have been already investigated … …Journal of Computer Science, Vol. 11, Issue 3 · 1 Apr 2015 · 6,715 accessesView PDFCite
