Table 2.

Statistical results of individual classification models and the two consensus models on the training set of 1667 chemicals. True Positives (TP) indicates the number of correctly classified positive chemicals, False Negatives (FN) indicates the number of misclassified positive chemicals, True Negative (TN) is the number of correctly classified positive chemicals, False positive (FP) refers to the misclassified experimentally negative chemicals. False rate is the fraction of incorrect predictions. Statistical parameters are the same as reported in Table 1.
