## Model Card for BiMediX-Bilingual |
|
|
|
### Model Details |
|
- **Name:** BiMediX |
|
- **Version:** 1.0 |
|
- **Type:** Bilingual Medical Mixture of Experts Large Language Model (LLM) |
|
- **Languages:** Arabic |
|
- **Model Architecture:** [Mixtral-8x7B-Instruct-v0.1](https://huggingface.co/mistralai/Mixtral-8x7B-Instruct-v0.1) |
|
- **Training Data:** BiMed1.3M-Arabic, an arabic dataset with diverse medical interactions. |
|
|
|
### Intended Use |
|
- **Primary Use:** Medical interactions in both English and Arabic. |
|
- **Capabilities:** MCQA, closed QA and chats. |
|
|
|
## Getting Started |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
model_id = "BiMediX/BiMediX-Ara" |
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_id) |
|
model = AutoModelForCausalLM.from_pretrained(model_id) |
|
|
|
text = "مرحبًا بيميديكس! لقد كنت أعاني من التعب المتزايد في الأسبوع الماضي." |
|
inputs = tokenizer(text, return_tensors="pt") |
|
|
|
outputs = model.generate(**inputs, max_new_tokens=500) |
|
print(tokenizer.decode(outputs[0], skip_special_tokens=True)) |
|
``` |
|
|
|
### Training Procedure |
|
- **Dataset:** BiMed1.3M-Arabic. |
|
- **QLoRA Adaptation:** Implements a low-rank adaptation technique, incorporating learnable low-rank adapter weights into the experts and the routing network. This results in training about 4% of the original parameters. |
|
- **Training Resources:** The model underwent training on the Arabic corpus. |
|
