📤 Output

The model predicts one of three risk categories:

Risk Level: High / Medium / Low
Probability: <VALUE>

Model predictions should not be interpreted as a medical diagnosis.

🔬 Methodology

1. Load and validate the dataset.
2. Perform exploratory data analysis.
3. Preprocess numerical and categorical features.
4. Address class imbalance using SMOTE.
5. Train classification models.
6. Perform hyperparameter optimization.
7. Evaluate model performance.
8. Deploy the prediction pipeline.

🛠️ Tech Stack

Python • Pandas • NumPy • Scikit-learn • Imbalanced-learn • Matplotlib • Seaborn • Streamlit

⚠️ Limitations

Model performance depends on the quality, representativeness, and distribution of the training data.

Healthcare-related datasets may contain sampling bias, class imbalance, missing information, and demographic differences that can affect model generalization.

This model has not been clinically validated and should not be used as a standalone medical decision system.

🔮 Future Improvements

• Explainable AI with SHAP
• Larger and more diverse datasets
• Probability calibration
• Fairness and bias evaluation
• External validation
• Model monitoring
• Advanced ensemble methods
• Clinical validation
