<h2>Présentation</h2>
|
| 284 |
+
<p>Cette API met à disposition un modèle de Machine Learning
|
| 285 |
+
entraîné pour suggérer le prix journalier optimal d'une location
|
| 286 |
+
de véhicule sur la plateforme Getaround.</p>
|
| 287 |
+
<p>Le modèle sous-jacent est un <strong>XGBoost Regressor</strong>
|
| 288 |
+
avec les performances suivantes sur le jeu de test :</p>
|
| 289 |
+
<ul>
|
| 290 |
+
<li>Erreur absolue moyenne (MAE) : <strong>9,18 EUR</strong></li>
|
| 291 |
+
<li>RMSE : <strong>12,82 EUR</strong></li>
|
| 292 |
+
<li>R² : <strong>0,846</strong></li>
