Llama2 7B for Telugu: 500 target vocabulary size + Mean target vocabulary initialization + 2x2LS/MTP/512 training

This model is built on top of Llama2 7B adapted for Telugu using 30K target language sentences sampled from CC-100.

Model Details

• Vocabulary: This model has an additional 500 target vocabulary.
• Target vocabulary initialization: The target weights of the embedding and LM head were initialized using Mean initialization.
• Training: This model was additionally pre-trained on 30K target language sentences sampled from CC-100. The training was conducted with the 2x2LS/MTP/512 strategies introduced in the paper.

Model Description

• Language: Telugu
• License: Llama 2 Community License Agreement
• Fine-tuned from model: meta-llama/Llama-2-7b-hf
