Intended Use

This model is designed to act as a mathematical assistant for Vietnamese speakers. It is particularly effective at:

• Solving simple algebra problems.
• Following Vietnamese instructional prompts for mathematical logic.

System Prompt

For best results, use the system prompt used during training:

Bạn là một chuyên gia toán học. Hãy giải bài toán sau bằng tiếng Việt.

Usage Example

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "PeterPaker123/Qwen2.5-7B-ViMetaMathQA-Mini"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    attn_implementation="flash_attention_2" # Recommended for H100/A100/L4
)

messages = [
    {"role": "system", "content": "Bạn là một chuyên gia toán học. Hãy giải bài toán sau bằng tiếng Việt."},
    {"role": "user", "content": "Tìm x, biết 2x + 5 = 15."}
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to("cuda")

outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Limitations

• Data Size: The model was fine-tuned on a 100,000-sample subset of the translated MetaMathQA dataset. While substantial, this represents only a portion of the full Vietnamese mathematical landscape and may not capture every specific niche or advanced mathematical dialect.
• Preliminary Model: This is an initial experiment utilizing the Qwen 2.5 architecture on specialized Vietnamese mathematical data. It is intended as a proof-of-concept for high-performance math reasoning on H100 hardware.
• Calculation Hallucination: Like all LLMs, the model may occasionally generate plausible-sounding but mathematically incorrect steps or hallucinate numerical values. Users should manually verify critical calculations.

Ethical Considerations

• Bias and Fairness: Like any other machine learning model, there is a possibility that this model might reproduce or amplify biases present in the training data. This includes biases inherited from the base Qwen model or specific patterns found in the translated MetaMathQA dataset.
• Use in Critical Systems: As this is a preliminary model intended for research and educational assistance, it is recommended not to use it for mission-critical applications without rigorous human-in-the-loop validation.
• Fine-tuning Data: The model was fine-tuned on a custom subset of 100,000 instruction samples in Vietnamese, translated from the MetaMathQA dataset.
