Quantitative validation of functional similarity of drug components. The figure shows the mean average precision for retrieving functionally similar chemicals as a function of the number of top chemicals considered. Results are shown for three representations: CCA (red), Chemical space (green), and Biological space (GSEA: blue, Gene expression: grey). Error bars show one standard error of the mean precision.
