Fig. 9From: Utilizing random Forest QSAR models with optimized parameters for target identification and its application to target-fishing serverThe ROC curve for screening results of the external validation set. 20% of active data and 93% of inactive data from external set have scores of 0, which makes a long straight line at the end of the curve. Active ligand with score of zero might represent novel chemical structures of bioactivity newly discovered by recent experimentsBack to article page
