Llama2 7B for Burmese: 100 target vocabulary size + FOCUS target vocabulary initialization

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

Model Details

Vocabulary: This model has an additional 100 target vocabulary.
Target vocabulary initialization: The target weights of the embedding and LM head were initialized using FOCUS initialization.
Training: This model was additionally pre-trained on 30K target language sentences sampled from CC-100.

Model Description

Language: Burmese

How to Get Started with the Model

Use the code below to get started with the model.

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModelForCausalLM

model = AutoModelForCausalLM.from_pretrained(
    "atsuki-yamaguchi/Llama-2-7b-hf-my-30K-focus"
)
model = PeftModelForCausalLM.from_pretrained(
    model,
    "atsuki-yamaguchi/Llama-2-7b-hf-my-30K-focus"
)
model = model.merge_and_unload()
tokenizer = AutoTokenizer.from_pretrained(
    "atsuki-yamaguchi/Llama-2-7b-hf-my-30K-focus"
)
