Fig. 4.

Comparison of the mean z-scores obtained by the different models and error bars indicate SEM. Bars are colored by compound features, which are blue bars for Mol2vec, green bars for ECFP${}_{\mathit{SS}}$, yellow bars for ECFP, purple bars for Mol2vec${}_{\mathit{SS}}$, and grey bars for SMILES. The bars highlighted with red border indicate the usage of ProtVec${}_{\mathit{AA}}$, which demonstrates better performance than other protein features
