Natural Language Processing

The NLP engine uses spaCy for entity recognition and pattern matching to extract relevant features from user queries. It handles various input patterns including:

Example Query Processing


Input: "35 year old single teacher with $50000 balance"
Output: {
    'age': 35,
    'job': 'teacher',
    'marital': 'single',
    'balance': 50000,
    'education': 'secondary',  # default
    'housing': 'no',          # default
    'loan': 'no'             # default
}
            

Machine Learning Model

The prediction system uses an XGBoost classifier with custom feature engineering and risk assessment. Key features include:

Feature Engineering


Engineered Features:
- Age Groups (18-25, 26-35, 36-45, 46-55, 55+)
- Balance Log Transform
- Risk Factors (loan status + job stability)
- Customer Value Indicators
            

Interactive Visualization

The dashboard uses D3.js to create interactive visualizations of predictions and feature contributions:
