## 🚀 Quick Start

### Installation

```bash
# Install from PyPI
poetry add kerasfactory

# Or install from source
git clone https://github.com/UnicoLab/KerasFactory
cd KerasFactory
poetry install
```

### 🚀 Quick Start Examples

#### Example 1: Smart Data Preprocessing

```python
import keras
from kerasfactory.layers import DistributionTransformLayer

# Create a simple model with automatic data transformation
inputs = keras.Input(shape=(10,))  # 10 numerical features

# Automatically transform data to normal distribution
transformed = DistributionTransformLayer(transform_type='auto')(inputs)

# Simple neural network
x = keras.layers.Dense(64, activation='relu')(transformed)
x = keras.layers.Dropout(0.2)(x)
outputs = keras.layers.Dense(1, activation='sigmoid')(x)

model = keras.Model(inputs=inputs, outputs=outputs)
model.compile(optimizer='adam', loss='binary_crossentropy', metrics=['accuracy'])

print("Model ready! The layer will automatically choose the best transformation for your data.")
```

#### Example 2: Intelligent Feature Fusion

```python
import keras
from kerasfactory.layers import GatedFeatureFusion

# Create two different representations of your data
inputs = keras.Input(shape=(8,))  # 8 features

# First representation: linear processing
linear_features = keras.layers.Dense(16, activation='relu')(inputs)

# Second representation: non-linear processing  
nonlinear_features = keras.layers.Dense(16, activation='tanh')(inputs)

# Intelligently combine both representations
fused_features = GatedFeatureFusion()([linear_features, nonlinear_features])

# Final prediction
outputs = keras.layers.Dense(1, activation='sigmoid')(fused_features)

model = keras.Model(inputs=inputs, outputs=outputs)
model.compile(optimizer='adam', loss='binary_crossentropy')

print("Smart feature fusion model ready! The layer learns which representation to trust more.")
```

#### Example 3: Ready-to-Use Models

```python
import keras
from kerasfactory.models import BaseFeedForwardModel

# Create a complete model with just one line!
model = BaseFeedForwardModel(
    feature_names=['age', 'income', 'education', 'experience'],
    hidden_units=[64, 32, 16],
    output_units=1,
    dropout_rate=0.2
)

# Your data (each feature as separate input)
age = keras.random.normal((100, 1))
income = keras.random.normal((100, 1)) 
education = keras.random.normal((100, 1))
experience = keras.random.normal((100, 1))

# Train with one command
model.compile(optimizer='adam', loss='mse')
model.fit([age, income, education, experience], 
          keras.random.normal((100, 1)), 
          epochs=10, verbose=0)

print("✅ Model trained successfully! No complex setup needed.")
```

#### Example 4: Date Feature Engineering

```python
import keras
from kerasfactory.layers import DateEncodingLayer

# Create a model that processes date information
inputs = keras.Input(shape=(4,))  # [year, month, day, day_of_week]

# Convert dates to cyclical features automatically
date_features = DateEncodingLayer()(inputs)

# Simple prediction model
x = keras.layers.Dense(32, activation='relu')(date_features)
outputs = keras.layers.Dense(1, activation='sigmoid')(x)

model = keras.Model(inputs=inputs, outputs=outputs)
model.compile(optimizer='adam', loss='binary_crossentropy')

print("📅 Date-aware model ready! Handles seasonality and cyclical patterns automatically.")
```

### 🧠 Smart Data Analyzer

```python
from kerasfactory.utils import analyze_data

# Get intelligent recommendations for your data
results = analyze_data("your_data.csv")
recommendations = results["recommendations"]

print("🎯 Recommended layers for your data:")
for layer in recommendations:
    print(f"  • {layer['layer_name']}: {layer['description']}")
    
print("✨ No more guessing which layers to use!")
```
