【 摘 要 】
Problem statement: Similarity based Virtual Screening (VS) deals with a large amount ofdata containing irrelevant and/or redundant fragments or features. Recent use of Bayesian network asan alternative for existing tools for similarity based VS has received noticeable attention of theresearchers in the field of chemoinformatics. Approach: To this end, different models of Bayesiannetwork have been developed. In this study, we enhance the Bayesian Inference Network (BIN) usinga subset of selected molecules features. Results: In this approach, a few features were filtered fromthe molecular fingerprint features based on a features selection approach. Conclusion: Simulatedvirtual screening experiments with MDL Drug Data Report (MDDR) data sets showed that theproposed method provides simple ways of enhancing the cost effectiveness of ligand-based virtualscreening searches, especially for higher diversity data set.
