# IA-Original |
|
|
|
IA-Original 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 and subsequently evaluated on a set of diverse tasks. |
|
|
|
The 11 languages covered by IA-Original are: Bhojpuri, Bengali, Gujarati, Hindi, Magahi, Marathi, Nepali, Oriya, Punjabi, Sanskrit, Urdu. |
|
