## 1. Introduction

**MEDfl** is an open-source **Federated Learning (FL)** framework designed for both **simulation** and **real-world distributed training**in the **medical and healthcare domains**. 
It integrates **Differential Privacy (DP)**, **Transfer Learning (TL)**, and secure communication to enable privacy-preserving model training across multiple institutions—particularly suited for **medical and clinical data**.


---

## 2. Key Features

- 🧩 **Two Operation Modes**

  - **Simulation Mode:** Run FL experiments locally for testing and benchmarking.
  - **Real-World Mode:** Connect remote clients for production-grade FL.

- 🔒 **Differential Privacy (Opacus Integration)**  
  Ensures client updates are mathematically protected against data leakage.

- 🧠 **Transfer Learning Integration**  
  Improve convergence and accuracy in small or heterogeneous datasets.

- ⚙️ **Modular Design**  
  Plug-and-play components for models, optimizers, datasets, and aggregation strategies.

---

## 3. Installation

```bash
pip install medfl
```

> ✅ Requires **Python 3.9+**.

If you prefer the development version:

```bash
git clone https://github.com/MEDomics-UdeS/MEDfl.git
cd MEDfl
pip install -e .
```

## 4. Modes of Operation

| Mode              | Description                                                        | Typical Use Case                                         |
| ----------------- | ------------------------------------------------------------------ | -------------------------------------------------------- |
| **Simulation FL** | Runs all clients locally in a controlled environment.              | Benchmarking, debugging, or prototyping.                 |
| **Real-World FL** | Connects distributed client machines. | Multi-institution collaboration, production deployments. |

## 5. Quick Start

### 🌍 Real-World Federated Learning Example

**Server Setup**

```python
from MEDfl.rw.server import FederatedServer, Strategy

custom_strategy = Strategy(
    name="FedAvg",
    fraction_fit=1,
    min_fit_clients=1,
    min_evaluate_clients=1,
    min_available_clients=1,
    local_epochs=1,
    threshold=0.5,
    learning_rate=0.01,
    optimizer_name="SGD",
    saveOnRounds=3,
    savingPath="./",
    total_rounds=10,
    datasetConfig={"isGlobal": True, "globalConfig": {"target": "label", "testFrac": 0.2}},
)

server = FederatedServer(
    host="0.0.0.0",
    port=8080,
    num_rounds=10,
    strategy=custom_strategy,
)
server.start()
```

**Client Setup**

```python
from MEDfl.rw.client import FlowerClient, DPConfig

# Example: XGBoost client
xgb_params = {
    "objective": "binary:logistic",
    "eval_metric": "logloss",
    "eta": 0.1,
    "max_depth": 6,
    "subsample": 0.8,
    "colsample_bytree": 0.8,
    "tree_method": "hist",  # GPU: "gpu_hist"
}

client = FlowerClient(
    server_address="100.65.215.27:8080",
    data_path="../data/client1.csv",
    dp_config=None,            # DP only applies to neural networks
    model_type="xgb",
    xgb_params=xgb_params,
    xgb_rounds=10,
)
client.start()
```

> 💡 **Tip:**  
> Use [Tailscale](https://tailscale.com) to connect clients and server under the same secure VPN for real-world deployments.

## 6. Documentation

You can generate and host the documentation locally with **Sphinx**:

```bash
cd docs
make clean && make html
cd _build/html
python -m http.server
```
