# MedleyMD
MedleyMD is a Mixure of Experts (MoE) made with the following models using [LazyMergekit](https://colab.research.google.com/drive/1obulZ1ROXHjYLn6PPZJwRR6GzgQogxxb?usp=sharing):
* [sethuiyer/Dr_Samantha_7b_mistral](https://huggingface.co/sethuiyer/Dr_Samantha_7b_mistral)
* [fblgit/UNA-TheBeagle-7b-v1](https://huggingface.co/fblgit/UNA-TheBeagle-7b-v1)
These models were chosen because `fblgit/UNA-TheBeagle-7b-v1` has excellent performance for a 7B parameter model and Dr.Samantha has capabilities of a medical knowledge-focused model (trained on USMLE databases and doctor-patient interactions) with the philosophical, psychological, and relational understanding, scoring 68.82% in topics related to clinical domain and psychology.
## Benchmark
On a synthetic benchmark of 15 medical diagnosis questions generated by GPT-4, GPT-4 also being an evaluator, MedleyMD scored **94.25/100**.
Nous Benchmark numbers shall be available soon.

## Ollama
MedleyMD can be used in ollama by running```ollama run stuehieyr/medleymd``` in your terminal.
If you have limited computing resources, check out this [video](https://www.youtube.com/watch?v=Qa1h7ygwQq8) to learn how to run it on
a Google Colab backend.
## 💻 Usage
```python
!pip install -qU transformers bitsandbytes accelerate
from transformers import AutoTokenizer
import transformers
import torch
model = "sethuiyer/MedleyMD"
tokenizer = AutoTokenizer.from_pretrained(model)
pipeline = transformers.pipeline(
"text-generation",
model=model,
model_kwargs={"torch_dtype": torch.bfloat16, "load_in_4bit": True},
)
generation_kwargs = {
"max_new_tokens": 512,
"do_sample": True,
"temperature": 0.7,
"top_k": 50,
"top_p": 95,
}
messages = [{"role":"system", "content":"You are an helpful AI assistant. Please use </s> when you want to end the answer."},
{"role": "user", "content": "Explain what a Mixture of Experts is in less than 100 words."}]
prompt = pipeline.tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
outputs = pipeline(prompt, **generation_kwargs)
print(outputs[0]["generated_text"])
```
```text
A Mixture of Experts (Mixout) is a neural network architecture that combines the strengths of multiple expert networks to make a more accurate and robust prediction.
It is composed of a topmost gating network that assigns weights to each expert network based on their performance on past input samples.
The expert networks are trained independently, and the gating network learns to choose the best combination of these experts to make the final prediction.
Mixout demonstrates a stronger ability to handle complex data distributions and is more efficient in terms of training time and memory usage compared to a
traditional ensemble approach.
