Fraud Detection Project using XGBoost
As part of a dynamic project focused on enhancing transaction security, I successfully implemented a fraud detection model utilizing XGBoost. The project aimed to identify and prevent fraudulent transactions, contributing to a robust and secure financial environment.
Key Components:
-
Model Selection:
- Implemented XGBoost as the primary machine learning model for fraud detection.
- Leveraged its ensemble learning capabilities for improved accuracy.
-
Performance Evaluation:
- Assessed model performance using key indicators:
- F1 Score
- Precision
- Recall
- Provided a comprehensive analysis of the model's effectiveness in identifying fraudulent activities.
- Assessed model performance using key indicators:
-
Explanatory Analysis:
- Employed SHAP (SHapley Additive exPlanations) analysis to interpret the model's decision-making process.
- Investigated and visualized the relationships between variables to enhance interpretability.
Achievements:
- Achieved notable results in minimizing false positives and false negatives, optimizing fraud detection accuracy.
- Contributed to a more secure financial system through the successful implementation of advanced machine learning techniques.
Technologies Used:
- XGBoost for machine learning model implementation.
- F1, Precision, and Recall as evaluation metrics.
- SHAP analysis for interpretability.
Outcome:
- The project resulted in an enhanced fraud detection system, improving the overall security and reliability of financial transactions.
