MLP-KTLim/llama-3-Korean-Bllossom-8B model fine tuning

(TREX-Lab at Seoul Cyber University)

Summary

• Base Model : MLP-KTLim/llama-3-Korean-Bllossom-8B
• Dataset : heegyu/open-korean-instructions (10%)
• Tuning Method
  • PEFT(Parameter Efficient Fine-Tuning)
  • LoRA(Low-Rank Adaptation of Large Language Models)
• Related Articles : https://arxiv.org/abs/2106.09685, https://arxiv.org/pdf/2403.10882
• Fine-tuning the Base Model with a random 10% of Korean chatbot data (open Korean instructions)
• Test whether fine tuning of a large language model is possible on A30 GPU*1 (successful)

• Developed by: [TREX-Lab at Seoul Cyber University]
• Language(s) (NLP): [Korean]
• Finetuned from model : [MLP-KTLim/llama-3-Korean-Bllossom-8B]

Fine Tuning Detail

• alpha value 16
• r value 64 (it seems a bit big...@@)

peft_config = LoraConfig(
    lora_alpha=16,
    lora_dropout=0.1,
    r=64,
    bias='none',
    task_type='CAUSAL_LM'
)

• Mixed precision : 4bit (bnb_4bit_use_double_quant)

bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_use_double_quant=True,
    bnb_4bit_quant_type='nf4',
    bnb_4bit_compute_dtype='float16',
)

• Use SFT trainer (https://huggingface.co/docs/trl/sft_trainer)

trainer = SFTTrainer(
    model=peft_model,
    train_dataset=dataset,
    dataset_text_field='text',
    max_seq_length=min(tokenizer.model_max_length, 2048),
    tokenizer=tokenizer,
    packing=True,
    args=training_args
)
