# Hybrid AI Architectures for Proactive Fraud Detection
## An XAI-Driven Optimization Framework

**Auteur:** Latif SINARE
**Programme:** Master MAII - FSTH, Universite Abdelmalek Essaadi

## Objectifs quantitatifs
Recall >= 90% - Precision >= 10% - AUPRC > 0,85 - FPR < 0,01%

## Pipelines
| Phase | Dataset | Modeles | Optimiseur |
|-------|---------|---------|------------|
| 1 | Kaggle CC | LightGBM | CMA-ES |
| 2 | PaySim | LSTM + RGAT + Stacking | PSO Async |
| 3 | IEEE-CIS | LSTM + RGAT + Stacking | PSO Async |
| 4 | AMLSim | RGAT | - |

## Pages du dashboard
1. Pipeline 1 - Kaggle CC: analyse interactive de transaction + SHAP
2. Pipeline 2 - PaySim: resultats Stacking + analyse heuristique
3. Pipeline 3 - IEEE-CIS: resultats complets + PSI drift monitoring
4. Performances: comparaison des 3 phases
