# 📌 EAS - Embedded Adaptive Stacking  
EAS (**Embedded Adaptive Stacking**) is a library for pattern detection in time series using **model stacking** with LSTM, GRU, BiLSTM, and BiGRU.

## 🚀 About the Project
EAS (**Embedded Adaptive Stacking**) is a library for time series analysis using **model stacking** based on recurrent neural networks.

### 🔹 **Key Features**
✔ **Smart Stacking**: Combines **LSTM, GRU, BiLSTM, and BiGRU** to improve predictions.  
✔ **Dynamic Optimization**: Includes the **LossAdaptiveOptimizer (LORO)**, which automatically adjusts the learning rate.  
✔ **Cost-Sensitive Loss Function**: `CustomLossWithRegression` allows fine-tuning penalties for extreme events.  
✔ **Results Visualization**: Clear comparison between predictions and actual values.

## 📀 Installation
To install the library directly from **PyPI**, use:
```bash
pip install adaptive-stacking-keras
```
Or to manually install the latest version from the repository:
```bash
git clone https://github.com/your-username/adaptive-stacking-keras.git
cd adaptive-stacking-keras
pip install .
```

## 📀 How to Use

### 🔹 **Usage Example**
Here is a simple example of **how to use the library** to train a model with **Stacking and dynamic optimization**.

```python
import tensorflow as tf
from adaptive_stacking_keras import (
    StackingModel,
    CustomLossWithRegression,
    LORO,
    plot_time_series_comparison,
)

# Creating the model with multiple hidden layers
hidden_dims = [64, 128]
model = StackingModel(input_dim=10, hidden_dims=hidden_dims, embedding_dim=32, output_dim=1)

# Creating LORO optimizer
optimizer = LORO(learning_rate=0.001)

# Generating synthetic data
tf.random.set_seed(42)
x_train = tf.random.normal((100, 10, 10))
y_train = tf.random.normal((100, 1))

# Training the model
for epoch in range(5):  # Only 5 epochs for demonstration
    with tf.GradientTape() as tape:
        y_pred, (threshold, alpha) = model(x_train)
        loss = CustomLossWithRegression(model.threshold_alpha_layer)(y_train, y_pred)
    gradients = tape.gradient(loss, model.trainable_variables)
    optimizer.apply_gradients(zip(gradients, model.trainable_variables))
    print(f"Epoch [{epoch+1}/5] - Loss: {loss.numpy():.4f} - Threshold: {threshold.numpy():.4f} - Alpha: {alpha.numpy():.4f}")

# Testing with data
x_test = tf.random.normal((50, 10, 10))
y_test = tf.random.normal((50, 1))
y_pred, _ = model(x_test)

# Visualization of results
plot_time_series_comparison(y_test, y_pred, time_range=(10, 40), title="Model Results")
```
