## Code Snippet for Data Processing
```python
import pandas as pd

# Load the dataset
data = pd.read_csv('[DATA].csv')

# Data preprocessing
# Remove duplicates
data = data.drop_duplicates()

# Handle missing values
data = data.fillna(data.mean())

# Feature engineering
# Create a new feature based on existing ones
data['feature_ratio'] = data['feature1'] / data['feature2']
```

## Explanation
- **Duplicate Removal**: Ensures no redundant data entries.
- **Missing Value Handling**: Replaces NaN values with the mean of the column.
- **Feature Engineering**: Creates a new feature by dividing two existing features.
