摘要
Support vector machine (SVM) was used to develop a nonlinear quantitative structure–activity relationship (QSAR) model for the prediction of the activities of the adenosine A 2A receptor antagonists. Six molecular descriptors selected by the heuristic method (HM) in CODESSA were used as inputs for SVM. The results obtained by SVM were compared with those obtained by HM. The mean squared errors (MSEs) for the training set given by HM and SVM are 0.08 and 0.05, respectively, which shows the performance of SVM model is better than that of the HM model.
