To solve this problem, use a new embedding called [`patch_type_embeddings`](https://github.com/graykode/commit-autosuggestions/blob/master/commit/model/diff_roberta.py#L40) that can distinguish added and deleted, just as the sample et al, 2019 (XLM) used language embeddeding. (1 for added, 2 for deleted.)
