## 🌟 Overview

TimeFlow Pro is a comprehensive platform for time series data analysis, preprocessing, and feature engineering. Designed for data scientists and analysts, it provides an intuitive interface for transforming raw time series data into ML-ready datasets with advanced preprocessing capabilities.

## 🚀 Key Features

### 📈 **Data Analysis & Visualization**
- **Interactive Data Exploration**: Real-time preview and statistics
- **Missing Value Analysis**: Smart detection and handling strategies
- **Outlier Detection**: Multiple methods including IQR, Z-Score, Isolation Forest
- **Temporal Analysis**: Seasonality detection, trend analysis, decomposition

### ⚙️ **Advanced Preprocessing Pipeline**
- **Feature Engineering**: Automatic lag features, rolling statistics, seasonal components
- **Stationarity Checking**: ADF tests and transformation suggestions
- **Data Scaling**: Robust, Standard, MinMax, and custom scaling methods
- **Feature Selection**: Correlation, variance, mutual information, RF importance

### 🏗️ **ML-Ready Outputs**
- **Train/Validation/Test Splits**: Time-based or random splitting
- **Multiple Export Formats**: CSV, Parquet, Excel, JSON
- **Model Integration**: Ready-to-use datasets for scikit-learn, XGBoost, LightGBM
- **Visual Reports**: Comprehensive pipeline execution reports

## 🎮 Quick Start

### 1. **Upload Your Data**
- Support for CSV, Excel, Parquet formats
- Automatic date parsing and validation
- Smart column type detection

### 2. **Configure Pipeline**
```python
# Example configuration
config = {
    'target_column': 'sales',
    'test_size': 0.2,
    'max_lags': 5,
    'seasonal_period': 365,
    'scaling_method': 'robust'
}
```

### 3. **Run Pipeline & Export**
- Execute full preprocessing pipeline
- Download processed data
- Get feature importance reports

config = {
    'target_column': 'target',
    'test_size': 0.2,
    'max_lags': 7,
    'seasonal_period': 30
}

# Create and run pipeline
pipeline = TimeFlowPipeline(config)
processed_data = pipeline.run(data)

# Get modeling data
modeling_data = pipeline.get_modeling_data()
X_train, y_train = modeling_data['X_train'], modeling_data['y_train']
```
