Model Card for Gemma2-2B-IT-Finetuned-KO-Bias-Detection

This model is fine-tuned from the base google/gemma-2-2b-it model using the Korean UnSmile Dataset, which focuses on identifying hate speech in Korean. The model detects various categories of hate speech, including but not limited to gender, race, age, and sexual orientation.

Model Details

Model Description

In this project, I fine-tuned the google/gemma-2-2b-it model using the Korean UnSmile Dataset—a comprehensive dataset for hate speech in Korean—released by Smilegate AI. The fine-tuned model is capable of identifying the following hate speech categories:

Women/Family: Stereotypes or derogatory remarks targeting women or family structures, including non-traditional families.
Men: Comments that demean or mock men.
LGBTQ+: Hate speech aimed at individuals based on sexual orientation or gender identity.
Race/Nationality: Offensive language or stereotypes related to race or nationality, such as insults towards specific ethnic groups or nationalities.
Age: Disparaging comments targeting specific age groups or generations.
Region: Hate speech directed at people from specific regions.
Religion: Negative or offensive comments aimed at religious groups or beliefs.
Other Hate Speech: Includes hate speech targeting other groups, such as individuals with disabilities or specific professions (e.g., police, journalists).

This fine-tuned model offers a practical solution for detecting toxic behavior on online platforms, helping ensure safer and more inclusive online environments by classifying harmful content efficiently and accurately.

Training Procedure

Environment Setup We fine-tuned the google/gemma-2-2b-it model using the Korean UnSmile Dataset. Note that versions of transformers before 4.38.1 contain bugs related to Gemma models. Please update to version 4.38.1 or later.

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=bnb_config, 
    device_map={"": 0}
)
tokenizer = AutoTokenizer.from_pretrained(model_id, add_eos_token=True)

Setting Up LoRA Configuration

python

from peft import LoraConfig, PeftModel, prepare_model_for_kbit_training, get_peft_model

model.gradient_checkpointing_enable()
model = prepare_model_for_kbit_training(model)

import bitsandbytes as bnb

def find_all_linear_names(model):
    cls = bnb.nn.Linear4bit  # For 4-bit precision
    lora_module_names = set()
    for name, module in model.named_modules():
        if isinstance(module, cls):
            names = name.split('.')
            lora_module_names.add(names[0] if len(names) == 1 else names[-1])
    if 'lm_head' in lora_module_names:  # Needed for 16-bit
        lora_module_names.remove('lm_head')
    return list(lora_module_names)

modules = find_all_linear_names(model)

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

model = get_peft_model(model, lora_config)

trainable, total = model.get_nb_trainable_parameters()
print(f"Trainable: {trainable} | Total: {total} | Percentage: {trainable/total*100:.4f}%")

Loading Training Data

python

from datasets import load_dataset
import pandas as pd

df = load_dataset('smilegate-ai/kor_unsmile')
df_hf = pd.concat([df['train'].to_pandas(), df['valid'].to_pandas()]).reset_index()

Preparing the Training Data The training data follows the Gemma conversation format:

shell

<start_of_turn>user
Comment: [User comment]<end_of_turn>
<start_of_turn>model
Hate Speech:
[Categories]<end_of_turn>

We create the prompts as follows:

python

def create_filtered_prompts_v2(row):
    labels = {
        "Women/Family": row['여성/가족'],
        "Men": row['남성'],
        "LGBTQ+": row['성소수자'],
        "Race/Nationality": row['인종/국적'],
        "Age": row['연령'],
        "Region": row['지역'],
        "Religion": row['종교'],
        "Other Hate Speech": row['기타 혐오']
    }

    non_zero_labels = [key for key, value in labels.items() if value == 1]

    if not non_zero_labels:
        non_zero_labels.append('None')

    return (
        "<start_of_turn>user\nComment: " + row['문장'] + "<end_of_turn>\n"
        "<start_of_turn>model\n"
        "Hate Speech: " + "\n".join(non_zero_labels) + "\n<end_of_turn>"
    )

df_hf['prompt'] = df_hf.apply(create_filtered_prompts_v2, axis=1)
df_hf = df_hf[["prompt", "문장"]].dropna()

Converting to Hugging Face Dataset Format

python

from datasets import Dataset
data = Dataset.from_pandas(df_hf)

Tokenizing the Data

python

data = data.map(lambda samples: tokenizer(samples["prompt"]), batched=True)
data = data.train_test_split(test_size=0.2)

)

import os

os.environ['PYTORCH_CUDA_ALLOC_CONF'] = 'expandable_segments:True'

model.config.use_cache = False  # Silence the warnings. Please re-enable for inference!
trainer.train()

Testing the Model

python

new_model = "Hyeonseo/gemma2-2b-it-finetuned-ko-bias-detection"

base_model = AutoModelForCausalLM.from_pretrained(
    model_id,
    low_cpu_mem_usage=True,
    return_dict=True,
    torch_dtype=torch.float16,
    device_map={"": 0},
)

merged_model = PeftModel.from_pretrained(base_model, new_model)
merged_model = merged_model.merge_and_unload()

# Save the merged model
merged_model.save_pretrained("merged_model", safe_serialization=True)
tokenizer.save_pretrained("merged_model")
tokenizer.pad_token = tokenizer.eos_token
tokenizer.padding_side = "right"

# Push the merged model to the Hugging Face Hub
merged_model.push_to_hub("Hyeonseo/gemma2-2b-it-finetuned-ko-bias-detection_merged", safe_serialization=True)

# Push the tokenizer to the Hugging Face Hub

Fine-tuned Model(gemma2-2b-it-finetuned-ko-bias-detection_merged)

Limitations and Bias

While the model is effective at detecting specific categories of hate speech in Korean, it may not generalize well to other forms of toxicity or to content in other languages. Additionally, the model's performance is contingent on the quality and representativeness of the training data. Users should be cautious and consider potential biases inherited from the dataset.
