Before revision:  By applying such approach on an existing CPI model, the modified version, with our proposed Protein Transformer as its protein learning module, has a significant improvement in the prediction performance . Practical tips for training Protein Transformer are also provided .
After revision:  By applying such approach on an existing CPI model, the modified version, with our proposed Protein Transformer as its protein learning module, has a significant improvement in the prediction performance when compared with several existing CPI models .
