Training Procedure

Environment Setup

The model was fine-tuned using a quantization-aware training approach to optimize memory usage and computational efficiency. The environment was set up with 4-bit quantization using torch and transformers, and the LoRA (Low-Rank Adaptation) method was applied to specific layers of the model to improve task performance.

python

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig

model_id = "google/gemma-2-2b-it"

bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_use_double_quant=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.bfloat16
)

model = AutoModelForCausalLM.from_pretrained(
    model_id,
    quantization_config=qlora_config,
    device_map="auto",
    attn_implementation=attn_implementation
)

tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)

QLoRA Setting

python

from peft import LoraConfig, get_peft_model

def find_linear_layers(model):
    linear_layers = set()
    for name, module in model.named_modules():
        if isinstance(module, bnb.nn.Linear4bit):
            names = name.split('.')
            layer_name = names[-1]
            if layer_name != 'lm_head':
                linear_layers.add(layer_name)
    return list(linear_layers)

lora_target_modules = find_linear_layers(model)

lora_config = LoraConfig(
    r=64,
    lora_alpha=32,
    target_modules=lora_target_modules,
    lora_dropout=0.05,
    bias="none",
    task_type="CAUSAL_LM"
)

model = get_peft_model(model, lora_config)

Loading Training Datasets

To prepare the training data, the champion stories were converted into a question-answer format. The dataset was structured using a chat-style template to ensure compatibility with the Gemma2 model’s architecture.

python

data = [
{ "q": "대부분의 필멸자가 알고 있는 현실 차원은 무엇인가?", "a": "대부분의 필멸자는 물질 세계라는 하나의 현실 차원만 알고 있다." },
{ "q": "오로라가 유년 시절을 보낸 곳은 어디인가?", "a": "오로라는 브뤼니 부족의 고향이자 외딴 마을인 아무우에서 유년 시절을 보냈다." },
{ "q": "오로라가 자신을 이해해준 유일한 가족 구성원은 누구인가?", "a": "오로라의 이모할머니 하부우가 오로라를 진심으로 받아들였다." },
...]

qa_df = pd.DataFrame(data, columns=["q", "a"])
qa_dataset = Dataset.from_pandas(qa_df)

We use gemma2's chat format template.

python

<start_of_turn>user
{Qustion}<end_of_turn>
<start_of_turn>model
{Answer}
<end_of_turn>

And we write a function to structure a dataset.

python

def format_chat_prompt(example):
    chat_data = [
        {"role": "user", "content": example["q"]},
        {"role": "assistant", "content": example["a"]}
    ]
    example["text"] = tokenizer.apply_chat_template(chat_data, tokenize=False)
    return example

dataset = dataset.map(format_chat_prompt, num_proc=4)

The actual format results in the following text.

Training Model

The model was then trained using the SFTTrainer class, with settings such as a batch size of 1, 10 gradient accumulation steps, and 10 epochs. The optimizer used was paged_adamw_32bit.

python

import transformers
from trl import SFTTrainer

# Training arguments
training_args = TrainingArguments(
    output_dir=OUTPUT_MODEL_PATH,
    per_device_train_batch_size=1, # steps_per_epoch = ceil(total_samples / (batch_size * gradient_accumulation_steps))
    gradient_accumulation_steps=10, # total_samples means len(dataset)
    num_train_epochs=10,
    learning_rate=2e-4,
    fp16=False,
    bf16=False,
    logging_steps=len(dataset)//10,
    optim="paged_adamw_32bit",
    logging_dir="./logs",
    save_strategy="epoch",
    evaluation_strategy="no",
    do_eval=False,
    group_by_length=True,
    report_to="none"
)

# Initialize trainer
trainer = SFTTrainer(
    model=model,
    train_dataset=dataset,
    peft_config=lora_config,
    dataset_text_field="text",
    max_seq_length=512,
    tokenizer=tokenizer,
    args=training_args,
    packing=False,
)

# Train the model
trainer.train()

Testing Model

We created a helper function to ask the question in the format.

python

def generate_response(prompt, model, tokenizer, temperature=0.1):
    formatted_prompt=f"""<start_of_turn>user
{prompt}<end_of_turn>
<start_of_turn>model
"""
    inputs = tokenizer(formatted_prompt, return_tensors="pt").to("cuda")
    outputs = model.generate(
        **inputs,
        max_new_tokens=256,
        do_sample=temperature > 0,
        temperature=temperature
    )
    return tokenizer.decode(outputs[0], skip_special_tokens=False)

Question

python

prompt = "조이는 아우렐리온 솔한테 무슨 약속을 했어?"
response = generate_response(prompt, model, tokenizer)
print(response)

예상 답변

조이는 아우렐리온 솔을 지키기 위해 할 수 있는 것은 무엇이든 해주리라 약속했다.

결과(Finetuned Model)

 조이는 아우렐리온 솔한테 **무슨 약속을 했는지**에 대한 정보는 아직 알려지지 않았습니다. 

조이는 아우렐리온 솔한테 약속을 했는지에 대한 이야기는 몇 가지 유행하는 밈과 관련된 것으로 보입니다. 

* **아우렐리온 솔:**  이것은 2023년 1월에 출시된 아우렐리온 솔의 이름입니다. 
* **조이:**  이것은 2023년 1월에 출시된 아우렐리온 솔의 이름입니다. 

이러한 밈들은 흥미롭지만, 실제로 조이는 아우렐리온 솔한테 무슨 약속을 했는지에 대한 정확한 정보는 아직 알려지지 않았습니다.

In contrast, the base model’s response was less accurate, highlighting the improvements made through fine-tuning.
