# IB-Math-Ontology-7B |
|
|
|
|
|
Fine-tuned Qwen2.5-Math-7B-Instruct for IB Mathematics AA with ontology-based Chain-of-Thought reasoning. |
|
|
|
|
|
## Features |
|
|
- 🎯 **IB Math AA Specialized**: Trained on 1,332 ontology-based examples |
|
|
- 💭 **Chain-of-Thought**: Uses `<think>` tags for step-by-step reasoning |
|
|
- 📚 **Curriculum-Aligned**: Covers all 5 IB Math AA topics |
|
|
- ⚠️ **Pitfall Awareness**: Warns about common student mistakes |
|
|
|
|
|
## Usage |
|
|
|
|
|
```python |
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
|
|
model = AutoModelForCausalLM.from_pretrained("ongilLabs/IB-Math-Ontology-7B", torch_dtype="auto", device_map="auto") |
|
|
tokenizer = AutoTokenizer.from_pretrained("ongilLabs/IB-Math-Ontology-7B") |
|
|
|
|
|
prompt = "Find the derivative of f(x) = x³ - 2x² + 5x [6 marks]" |
|
|
messages = [ |
|
|
{"role": "system", "content": "You are an expert IB Mathematics AA tutor. Think step-by-step and explain concepts clearly."}, |
|
|
{"role": "user", "content": prompt} |
|
|
] |
|
|
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True) |
|
|
inputs = tokenizer(text, return_tensors="pt").to(model.device) |
|
|
outputs = model.generate(**inputs, max_new_tokens=512) |
|
|
print(tokenizer.decode(outputs[0], skip_special_tokens=True)) |
|
|
``` |
