Llama2 7B for Sinhala: 1000 target vocabulary size + Align target vocabulary initialization + 2x2LS/MTP/512 training

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

Model Details

Vocabulary: This model has an additional 1000 target vocabulary.
Target vocabulary initialization: The target weights of the embedding and LM head were initialized using Align 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: Sinhala
License: Llama 2 Community License Agreement
Fine-tuned from model: meta-llama/Llama-2-7b-hf
