Tokenizer

We enhance our previous tokenizer in vietnamese-llama2-7b-40GB by training SentencePiece on a more extensive collection of clean Vietnamese documents spanning diverse domains such as news, books, stock, finance, and laws. In contrast to the previous version, we follow the original LLaMA-2 paper to split all numbers into individual digits. Again, the updated tokenizer markedly enhances the encoding of Vietnamese text, cutting down the number of tokens by 50% compared to ChatGPT and approximately 70% compared to the original Llama2.

Pretraining data

Here are our data sources:

• 53 GB NewsCorpus (clean + dedup binhvq's NewsCorpus combined with our self-crawled data up to October 2023). Thanks iambestfeed for his great work in crawling news data.
• 1.3 GB Vietnamese Wikipedia (updated to October 2023)
• 8.5 GB Vietnamese books
• 4.8 GB Vietnamese legal documents (clean and dedup)
• 1.6 GB stock news (clean and dedup)
• 43 GB Vietnamese text (subsampled from Culturax-vi)
• 2.3 GB English Books (sub-sampled from pg19)
• 2.2 GB English Wikipedia
• 16 GB English text (subsampled from Culturax-en)

We then merge all data sources and perform the last deduplication, resulting in a final pretraining dataset of 124 GB, including 104 GB of Vietnamese text and 20 GB of English text.

Continual pretraining

We conduct a single-epoch continual pretraining using the Llama2-7B model.

We trained the model on a DGX A100 system, utilizing four GPU A100 in 40 days (about 4000 GPU hours).

Hyperparameters are set as follows:

• Training Regime: BFloat16 mixed precision

• Lora Config:

  {
    "base_model_name_or_path": "meta-llama/Llama-2-7b-hf",
    "bias": "none",
    "enable_lora": null,
    "fan_in_fan_out": false,
    "inference_mode": true,
    "lora_alpha": 32.0,
    "lora_dropout": 0.05,
    "merge_weights": false,
    "modules_to_save": [
      "embed_tokens",
      "lm_head"
    ],
    "peft_type": "LORA",
    "r": 8,
    "target_modules": [
      "q_proj",
      "v_proj",
      "k_proj",
      "o_proj",
      "gate_proj",
      "down_proj",
      "up_proj"
    ],
    "task_type": "CAUSAL_LM"
  }
  

We also provide the LoRA part so that you can integrate it with the original Llama2-7b by yourself.

Please note that this model requires further supervised fine-tuning (SFT) to be used in practice!

Usage and other considerations: We refer to the Llama 2
