Fig. 4. Precision of the predicted inter-residue contacts by the variant ProFOLD w/o R.

a For the 31 CASP13 FM targets, the precision increases with the receptive field size and finally reaches 0.382. b On the validation set with 1820 proteins, the precision also increases with the receptive field size and finally reaches 0.424. Even using the "encoder and aggregator'' framework alone, the variant ProFOLD w/o R still outperformed CCMpred on the two datasets (0.219 and 0.382, respectively).
