+ # IA-Transliterated
18
+
19
+ IA-Transliterated is a multilingual RoBERTa model pre-trained exclusively on 11 Indian languages from the Indo-Aryan language family. It is pre-trained on the monolingual corpora of these languages. All the languages are transliterated into the Devanagari script. It is subsequently evaluated on a set of diverse tasks.
20
+
21
+ The 11 languages covered by IA-Transliterated are: Bhojpuri, Bengali, Gujarati, Hindi, Magahi, Marathi, Nepali, Oriya, Punjabi, Sanskrit, Urdu.
22
+
23
+ The code can be found [here](https://github.com/IBM/NL-FM-Toolkit). For more information, check-out our [paper](https://aclanthology.org/2021.emnlp-main.675/).
