Explainable Credit Card Fraud Detection

This public Hugging Face Space hosts a free static web app for a final-year research project on credit-card fraud detection.

The deployed version runs the exported XGBoost model directly in the browser from xgb_final_model.json, so it does not require paid Gradio CPU, paid GPU, paid APIs, hosted databases, or external inference endpoints.

Features

• —Single-transaction fraud scoring.
• —CSV batch scoring in the browser.
• —Evaluation dashboard with PR-AUC, ROC-AUC, F1, precision, recall, MCC, and visualizations.
• —Explainability page with SHAP and XGBoost gain summaries.
• —Dataset and methodology notes.
