About Transformer task prefix
Hi all,I am a new user, please forgive me if my question is too silly, but I tried many searches and still cannot find a satisfactory solution so here I am.I want to fine-tune the T5 model with my sequence to sequence task that take one sentence as input and generate another sentence correspondingly. I read many examples from huggingface community notebooks and other sources, and i found there is a prefix added to the input or target.prefix at inputarticle.prefix at outputnotebook.Can I build whatever prefix by myself ? e.g. ‘paraphrase_sentence’, or it is a something already fixed by authors ?I also want to know where should I add the prefix for my case (input or output) ? and what prefix should I add for my case?my data is like:sentence_a1, sentence_b1,sentence_a2, sentence_b2,…and I would to train a model that can generate a sentence to a given sentence.something similar to paraphrase.
