For fine-tuning details, see the [paper](https://arxiv.org/abs/2203.05437). You can use MultiIndicWikiBioSS to build biography generation applications for Indian languages by fine-tuning the model with supervised training data. Some salient features of the MultiIndicWikiBioSS are: You can read more about MultiIndicWikiBioSS in this paper. ## Using this model in `transformers` ``` from transformers import MBartForConditionalGeneration, AutoModelForSeq2SeqLM from transformers import AlbertTokenizer, AutoTokenizer tokenizer = AutoTokenizer.from_pretrained("ai4bharat/MultiIndicWikiBioSS", do_lower_case=False, use_fast=False, keep_accents=True) # Or use tokenizer = AlbertTokenizer.from_pretrained("ai4bharat/MultiIndicWikiBioSS", do_lower_case=False, use_fast=False, keep_accents=True) model = AutoModelForSeq2SeqLM.from_pretrained("ai4bharat/MultiIndicWikiBioSS") # Or use model = MBartForConditionalGeneration.from_pretrained("ai4bharat/MultiIndicWikiBioSS") # Some initial mapping bos_id = tokenizer._convert_token_to_id_with_added_voc("") eos_id = tokenizer._convert_token_to_id_with_added_voc("") pad_id = tokenizer._convert_token_to_id_with_added_voc("") # To get lang_id use any of ['<2as>', '<2bn>', '<2hi>', '<2kn>', '<2ml>', '<2or>', '<2pa>', '<2ta>', '<2te>'] # First tokenize the input and outputs.
