## Data Format

The CLI expects CSV files with the following characteristics:

- **Headers**: First row should contain column names
- **Features**: Numerical or categorical features (categorical will be automatically encoded)
- **Target**: Binary classification target (0/1 or categorical labels)
- **Missing Values**: Will be automatically filled with mean values for numerical columns

### Example CSV Format:
```csv
pregnancies,glucose,blood_pressure,skin_thickness,insulin,bmi,diabetes_pedigree,age,outcome
6,148,72,35,0,33.6,0.627,50,1
1,85,66,29,0,26.6,0.351,31,0
8,183,64,0,0,23.3,0.672,32,1
```

## Model Architecture

The MLP model uses the following architecture:

- **Input Layer**: Matches the number of features in your dataset
- **Hidden Layers**: Configurable (default: [64, 32] neurons)
- **Activation**: ReLU activation functions
- **Regularization**: Dropout (0.2) between layers
- **Output Layer**: 2 neurons for binary classification
- **Initialization**: Xavier uniform weight initialization

## Configuration

You can customize default settings by editing `config.json`:

```json
{
  "federated_learning": {
    "server_base_url": "https://your-server.com",
    "client_id": "your_client_id"
  },
  "model": {
    "hidden_sizes": [128, 64, 32],
    "dropout_rate": 0.3
  },
  "training": {
    "default_epochs": 20,
    "default_batch_size": 64,
    "default_learning_rate": 0.001
  }
}
```

## Logging

Training and evaluation activities are automatically logged to:
- Console output with rich formatting
- Log files (when specified)
- Training history for federated learning rounds

## Example Workflow

Here's a complete federated learning workflow:

```bash
# 1. Train local model
python cli.py train ./data/sample_diabetes_client1.csv --rounds 10 --log ./logs/round1.log

# 2. Evaluate local model
python cli.py evaluate ./models/local_model.pth ./data/sample_diabetes_test.csv --save

# 3. Download global model from server
python cli.py sync https://federated-server.com/global_model.pth

# 4. Upload local model weights
python cli.py upload ./models/local_model.pth https://federated-server.com/upload --round 1

# 5. Compare models
python cli.py compare ./models/local_model.pth ./models/global_model.pth --test-data ./data/sample_diabetes_test.csv
```

## Troubleshooting

### Common Issues

1. **Import Errors**: Make sure all dependencies are installed with `pip install -r requirements.txt`

2. **CUDA Issues**: The client automatically detects and uses GPU if available, falls back to CPU

3. **File Not Found**: Ensure data files exist and paths are correct

4. **Model Loading Errors**: Check that model files are valid PyTorch models

5. **Network Issues**: For sync operations, ensure server URLs are accessible
