+> [!NOTE]
 > If you run an experiment with the same configuration settings and primary metric multiple times, you'll likely see variation in each experiments final metrics score and generated models. The algorithms automated ML employs have inherent randomness that can cause slight variation in the models output by the experiment and the recommended model's final metrics score, like accuracy. You'll likely also see results with the same model name, but different hyperparameters used.
