## Model Card for BiMediX-Bilingual
|
||
|
|
|
||
|
|
### Model Details
|
||
|
|
- **Name:** BiMediX
|
||
|
|
- **Version:** 1.0
|
||
|
|
- **Type:** Bilingual Medical Mixture of Experts Large Language Model (LLM)
|
||
|
|
- **Languages:** English, Arabic
|
||
|
|
- **Model Architecture:** [Mixtral-8x7B-Instruct-v0.1](https://huggingface.co/mistralai/Mixtral-8x7B-Instruct-v0.1)
|
||
|
|
- **Training Data:** BiMed1.3M, a bilingual 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-Bi"
|
||
|
|
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
||
|
|
model = AutoModelForCausalLM.from_pretrained(model_id)
|
||
|
|
text = "Hello BiMediX! I've been experiencing increased tiredness in the past week."
|
||
|
|
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, 632 million healthcare specialized tokens.
|
||
|
|
- **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 approximately 632 million tokens from the Arabic-English corpus, including 288 million tokens exclusively for English.
|
||
|
|
|
||
|
|
### Model Performance
|
||
|
|
- **Benchmarks:** Outperforms the baseline model and Jais-30B in medical evaluations.
