### Full Installation (includes all optional dependencies)
```bash
pip install ABgrouponline[full]
```

### From Source
```bash
git clone https://github.com/abgroup/ABgrouponline.git
cd ABgrouponline
pip install -e .
```

## 🎯 Quick Start

### Basic Model Loading
```python
from abgrouponline import ModelManager, load_model

# Initialize model manager
manager = ModelManager()

# Load a pre-trained diabetes prediction model
diabetes_model = load_model('diabetes_ensemble', version='latest')

# Make predictions
predictions = diabetes_model.predict(data)
```

### Healthcare Prediction Example
```python
from abgrouponline.healthcare import DiabetesClassifier
from abgrouponline.data import load_pima_dataset

# Load dataset
data = load_pima_dataset()

# Initialize classifier with imbalance handling
classifier = DiabetesClassifier(
    model_type='random_forest',
    imbalance_method='smote',
    hyperparameter_tuning=True
)

# Train model
classifier.fit(data.X_train, data.y_train)

# Evaluate
results = classifier.evaluate(data.X_test, data.y_test)
print(f"Accuracy: {results['accuracy']:.3f}")
print(f"F1-Score: {results['f1_score']:.3f}")
```

### Brain Imaging Model Example
```python
from abgrouponline.brain_imaging import GM_LDM
from abgrouponline.data import load_brain_data

# Load brain imaging data
brain_data = load_brain_data('abcd_dataset')

# Initialize GM-LDM model
gm_ldm = GM_LDM(
    autoencoder_dim=3,
    latent_dim=512,
    use_vit_encoder=True
)

# Train model
gm_ldm.fit(brain_data.functional_connectivity, brain_data.gray_matter)

# Generate synthetic brain data
synthetic_data = gm_ldm.generate(conditions=brain_data.fnc_sample)
```

### Language Model Alignment Example
```python
from abgrouponline.language_models import ABCAlign
from abgrouponline.alignment import SafetyPrinciples

# Define safety principles
principles = SafetyPrinciples(
    accuracy=True,
    bias_mitigation=True,
    transparency=True
)

# Initialize alignment framework
aligner = ABCAlign(
    base_model='llama3-8b',
    principles=principles,
    optimization_method='orpo'
)

# Align model
aligned_model = aligner.align(training_data, validation_data)

# Evaluate alignment
safety_scores = aligner.evaluate_safety(test_data)
```

### Time Series Forecasting Example
```python
from abgrouponline.forecasting import NourishNet
from abgrouponline.data import load_commodity_data

# Load food commodity data
commodity_data = load_commodity_data(['wheat', 'rice', 'corn'])

# Initialize forecasting model
nourish_net = NourishNet(
    forecast_horizon=30,
    severity_classification=True,
    early_warning=True
)

# Train model
nourish_net.fit(commodity_data.prices, commodity_data.indicators)

# Forecast prices and severity
forecasts = nourish_net.predict(horizon=30)
severity_alerts = nourish_net.get_severity_alerts()
```
