BERT-PPII: The Polyproline Type II Helix Structure Prediction Model Based on BERT and Multichannel CNN

Figure 1

The flowchart of BERT-PPII model including input protein sequence samples, BERT embedding encoding and global feature extraction, local feature extraction by multichannel convolution, multifeature fusion, and prediction. It is assumed that the sliding window size is 13 and the amino acid residues in the sample are separated by space in the figure.
