For fine-tuning details, see the [paper](https://arxiv.org/abs/2203.05437). You can use MultiIndicWikiBio to build biography generation applications for Indian languages by fine-tuning the model with supervised training data. Some salient features of the MultiIndicWikiBio are: You can read more about MultiIndicWikiBioUnified in this paper. ## Using this model in `transformers` ``` from transformers import MBartForConditionalGeneration, AutoModelForSeq2SeqLM from transformers import AlbertTokenizer, AutoTokenizer tokenizer = AutoTokenizer.from_pretrained("ai4bharat/MultiIndicWikiBioUnified", do_lower_case=False, use_fast=False, keep_accents=True) # Or use tokenizer = AlbertTokenizer.from_pretrained("ai4bharat/MultiIndicWikiBioUnified", do_lower_case=False, use_fast=False, keep_accents=True) model = AutoModelForSeq2SeqLM.from_pretrained("ai4bharat/MultiIndicWikiBioUnified") # Or use model = MBartForConditionalGeneration.from_pretrained("ai4bharat/MultiIndicWikiBioUnified") # 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.

After you get the output, you should convert it back into the original script. ## Benchmarks Scores on the `IndicWikiBio` test sets are as follows: Language | RougeL ---------|---------------------------- as | 56.28 bn | 57.42 hi | 67.48 kn | 40.01 ml | 38.84 or | 67.13 pa | 52.88 ta | 51.82 te | 51.43 ## Citation If you use this model, please cite the following paper: ``` @inproceedings{Kumar2022IndicNLGSM, title={IndicNLG Suite: Multilingual Datasets for Diverse NLG Tasks in Indic Languages}, author={Aman Kumar and Himani Shrotriya and Prachi Sahu and Raj Dabre and Ratish Puduppully and Anoop Kunchukuttan and Amogh Mishra and Mitesh M.
