The enrichment plotter node allows you to plot enrichment curves. Enrichment curves are common in cheminformatics and molecular modeling. A model is trained on a few number of compounds with known activity and then a large number of molecules with unknown activity together with the training compounds are classified by the model. Then the molecules are sorted by the predicted activity value and a line is plotted where the sum of hits among the first x compounds is shown on the y -axis. The steeper the line, the better the enrichment is.
