What is IndicBERT?
IndicBERT is a groundbreaking multilingual ALBERT model specifically designed for Indian languages. Developed by AI4Bharat, it has been pre-trained on an extensive corpus of 9 billion tokens across 12 major Indian languages: Assamese, Bengali, English, Gujarati, Hindi, Kannada, Malayalam, Marathi, Oriya, Punjabi, Tamil, and Telugu. The model stands out for its efficient architecture, requiring fewer parameters than other multilingual models while maintaining competitive performance.
Implementation Details
The model utilizes the ALBERT architecture optimized for Indian language processing. It has been trained on AI4Bharat's carefully curated monolingual corpus, with Hindi (1.84B tokens) and English (1.34B tokens) comprising the largest portions of the training data. The model achieves impressive results on the IndicGLUE benchmark, outperforming both mBERT and XLM-R on several tasks.
