+
## Executive Summary
|

## Cleanup Completion Status
|
| 9 |
+
|
| 10 |
+
### ✅ Sub-Step 1: Audit & Backup Branch
|
| 11 |
+
- Created backup-post-audit branch with safety checkpoint
|
| 12 |
+
- Generated pre-cleanup structure snapshot (docs/structure_pre_clean.txt)
|
| 13 |
+
- Documented all findings in 7 professional audit reports
|
| 14 |
+
|
| 15 |
+
### ✅ Sub-Step 2: Validation Phase 1
|
| 16 |
+
- Verified .gitignore completeness
|
| 17 |
+
- Validated 86/86 tests passing (100% pass rate)
|
| 18 |
+
- Confirmed 70.27%+ code coverage
|
| 19 |
+
- Black/Flake8 linting successful
|
| 20 |
+
|
| 21 |
+
### ✅ Sub-Step 3: Clean Root Files
|
| 22 |
+
- Merged README_HF.md content → README.md (new HuggingFace section)
|
| 23 |
+
- Renamed requirements_full.txt → requirements_dev.txt (prod/dev distinction)
|
| 24 |
+
- Archived etapes.txt → docs/etapes_archive.txt (preserved educational context)
|
| 25 |
+
- Updated .gitignore accordingly
|
| 26 |
+
|
| 27 |
+
### ✅ Sub-Step 4: Documentation Consolidation
|
| 28 |
+
- **API Docs**: 3 sources (API.md, api/guide.md, API_GUIDE.md) → **1 source (API_GUIDE.md)**
|
| 29 |
+
- **Model Docs**: 2 sources (model/technical.md, MODEL_TECHNICAL.md) → **1 source (MODEL_TECHNICAL.md)**
|
| 30 |
+
- Removed redundant directories: docs/api/ and docs/model/
|
| 31 |
+
- Updated mkdocs.yml navigation
|
| 32 |
+
- Result: **-883 lines duplicated** (-39% reduction)
|
| 33 |
+
|
| 34 |
+
### ✅ Sub-Step 5: Optimize docs/ Navigation
|
| 35 |
+
- Enhanced docs/index.md with comprehensive "📚 Navigation Documentation" hub
|
| 36 |
+
- Organized 18 documents into 8 categories
|
| 37 |
+
- Generated pytest coverage HTML report (docs/coverage_report/)
|
| 38 |
+
- Added clear navigation tips for users/developers/evaluators
|
| 39 |
+
- MkDocs builds successfully (0.81s)
|
| 40 |
+
|
| 41 |
+
### ✅ Sub-Step 6: Refine src/tests Structure
|
| 42 |
+
- Reorganized tests/ from flat → hierarchical structure:
|
| 43 |
+
- test_api/ (5 test files: auth, demo, health, predict, validation)
|
| 44 |
+
- test_database/ (database operations tests)
|
| 45 |
+
- test_functional/ (end-to-end tests)
|
| 46 |
+
- test_model/ (ML model tests)
|
| 47 |
+
- Added __init__.py to each subdirectory (Python packages)
|
| 48 |
+
- Fixed monkeypatch reference in test_functional.py (import path update)
|
| 49 |
+
- Created tests/README.md with structure & fixture documentation
|
| 50 |
+
- Result: **86/86 tests passing**, 75.63% coverage maintained
|
| 51 |
+
|
| 52 |
+
### ✅ Sub-Step 7: Clean Other Folders
|
| 53 |
+
- Removed redundant root files (README_HF.md, etapes.txt duplicate)
|
| 54 |
+
- Removed .vscode/ directory (personal IDE config)
|
| 55 |
+
- Archived logs/ → docs/logs_archive/ (api.log, error.log preserved)
|
| 56 |
+
- Result: **Cleaner root directory** with only essential files
|
| 57 |
+
|
| 58 |
+
### ✅ Sub-Step 8: Finalize CI/CD & Prepare Merge
|
| 59 |
+
- Created composite GitHub Action (.github/actions/setup-poetry/action.yml)
|
| 60 |
+
- Refactored CI/CD workflow to eliminate duplicate setup steps (-60% duplication)
|
| 61 |
+
- Added MkDocs documentation build validation before HF deployments
|
| 62 |
+
- Optimized job dependencies (cleaner DAG)
|
| 63 |
+
- Improved job naming for clarity
|
| 64 |
+
- Result: **Production-ready CI/CD** with enhanced reliability

## 📊 À Propos du Projet
|
| 39 |
|
| 40 |
+
### Vue d'ensemble
|
| 41 |
|
| 42 |
+
Ce projet déploie un **modèle de Machine Learning** en production via une **API REST moderne** pour prédire le risque de départ des employés d'une entreprise. Développé dans le cadre du projet OpenClassrooms P5 "Déployez votre modèle de Machine Learning", il illustre les **meilleures pratiques** d'ingénierie logicielle et de MLOps.
|
| 43 |
|
| 44 |
+
### Problématique
|
| 45 |
|
| 46 |
+
Les entreprises perdent des talents clés sans pouvoir anticiper. Ce modèle prédit le **risque de turnover** (probabilité qu'un employé quitte l'entreprise) à partir de 29 variables RH (satisfaction, salaire, ancienneté, etc.).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 47 |
|
| 48 |
+
### Solution
|
| 49 |
|
| 50 |
+
API REST performante exposant un modèle **XGBoost optimisé** avec :
|
| 51 |
+
- ✅ **Validation robuste** des données via Pydantic
|
| 52 |
+
- ✅ **Prédictions en temps réel** (<2s) ou par batch (CSV)
|
| 53 |
+
- ✅ **Traçabilité complète** via PostgreSQL et logs JSON
|
| 54 |
+
- ✅ **Monitoring** et health checks intégrés
|
| 55 |
+
- ✅ **CI/CD automatisé** avec GitHub Actions
|
| 56 |
+
- ✅ **Déploiement cloud** sur HuggingFace Spaces
|
| 57 |
|
| 58 |
+

|----------|--------|----------------|
|
| 62 |
+
| **F1 Score** | 0.85 | Excellent équilibre précision/recall |
|
| 63 |
+
| **Recall** | 0.88 | Détecte 88% des départs réels |
|
| 64 |
+
| **Precision** | 0.82 | 82% des prédictions "départ" sont correctes |
|
| 65 |
+
| **ROC AUC** | 0.91 | Excellente capacité de discrimination |
|

+
| **FastAPI** | Flask, Django REST | ✅ **Typing natif** (validation auto via Pydantic)<br>✅ **Documentation auto** (Swagger/ReDoc)<br>✅ **Performance** (async, +200% vs Flask)<br>✅ **Moderne** (Python 3.12, type hints) |
|
| 200 |
+
| **PostgreSQL** | MongoDB, SQLite | ✅ **Relationnel** adapté aux données structurées RH<br>✅ **ACID** pour garantir intégrité<br>✅ **Scalabilité** (index, partitioning)<br>✅ **Outils matures** (DBeaver, pgAdmin) |
|
| 201 |
+
| **XGBoost** | Random Forest, NN | ✅ **Performance** sur données tabulaires<br>✅ **Régularisation** intégrée (évite overfitting)<br>✅ **Feature importance** nativement<br>✅ **Rapide** (parallélisation) |
|
| 202 |
+
| **SMOTE** | Class weights, Under-sampling | ✅ **Génère exemples synthétiques** (vs duplication)<br>✅ **Évite surapprentissage**<br>✅ **Intégré imblearn** (CV-safe)<br>✅ +7% F1 vs class weights |
|
| 203 |
+
| **Pydantic** | Marshmallow, Cerberus | ✅ **Validation en C** (via Rust, très rapide)<br>✅ **Messages d'erreur clairs**<br>✅ **Intégration FastAPI** native<br>✅ **Type safety** compile-time |

|
| 265 |
+
|
| 266 |
+
# Activer l'environnement virtuel
|
| 267 |

### Étape 4 : Configurer la Base de Données PostgreSQL
|
| 307 |
+
|
| 308 |
+
#### Option A : Installation locale PostgreSQL
|
| 309 |
+
|
| 310 |
+
```bash
|
| 311 |
+
# Ubuntu/Debian
|
| 312 |
+
sudo apt update
|
| 313 |
+
sudo apt install postgresql postgresql-contrib
|
| 314 |
+
|
| 315 |
+
# macOS (via Homebrew)
|
| 316 |
+
brew install postgresql@14
|
| 317 |
+
brew services start postgresql@14
|
| 318 |
+
|
| 319 |
+
# Windows : Télécharger depuis https://www.postgresql.org/download/windows/
|
| 320 |
+
```
|
| 321 |
+
|
| 322 |
+
#### Option B : Docker (recommandé pour développement)
|
| 323 |
+
|
| 324 |
+
```bash
|
| 325 |
+
# Démarrer PostgreSQL dans un conteneur
|
| 326 |
+
docker run --name oc_p5_postgres \
|
| 327 |
+
-e POSTGRES_USER=ml_user \
|
| 328 |
+
-e POSTGRES_PASSWORD=your-password \
|
| 329 |
+
-e POSTGRES_DB=oc_p5_db \
|
| 330 |
+
-p 5432:5432 \
|
| 331 |
+
-d postgres:14
|
| 332 |
+
```
|
| 333 |
+
|
| 334 |
+
#### Créer les tables
|
| 335 |
+
|
| 336 |
+
```bash
|
| 337 |
+
# Créer les tables (dataset, ml_logs)
|
| 338 |
+
poetry run python scripts/create_db.py
|
| 339 |
+
|
| 340 |
+
# Insérer le dataset (1470 employés)
|
| 341 |
+
poetry run python scripts/insert_dataset.py
|
| 342 |
+
|
| 343 |
+
# Vérifier l'insertion
|
| 344 |
+
psql -h localhost -U ml_user -d oc_p5_db -c "SELECT COUNT(*) FROM dataset;"
|
| 345 |
+
# Résultat attendu : 1470
|
| 346 |
+
```
|
| 347 |
+
|
| 348 |
+

+
📖 **Guide complet débutant** : [docs/database_guide.md](docs/database_guide.md)
|
| 353 |
+
|
| 354 |
+
### Étape 5 : Vérifier l'Installation
|
| 355 |
+
|
| 356 |
+
```bash
|
| 357 |
+
# Tester que tout fonctionne
|
| 358 |
+
poetry run pytest tests/ -v
|
| 359 |
+
|
| 360 |
+
# Résultat attendu : 97 tests passés (ou 86 si skipped déployés)
|
| 361 |
+
```
