Prediction performance comparison of TANGLE with ANGLOR and the random amino acid-specific predictor.

Prediction performance is categorized according to twenty amino acid types, three secondary structure types (H, helix; E, beta-strand; and C, coil) and two-state solvent accessibility (E, exposed and B, buried), evaluated by the mean absolute error (MAE). The results were obtained using an independent test set of 1,026 proteins from the set of PDB data compiled by Wu and Zhang [11], where the rest 500 proteins were used for training.
aTwenty amino acid types.
bThree secondary structure types. H: alpha-helix; E: beta-strand; C: coil.
cTwo-class solvent accessibility: E: exposed; B: buried.
