Une référence de base est un modèle, score, processus ou résultat de référence utilisé pour juger si un système plus complexe apporte une amélioration. En apprentissage automatique, elle aide à définir la performance minimale attendue qu’un nouveau modèle devrait dépasser pour justifier une complexité ou un coût supplémentaire.
A model used as a reference point for comparing how well another model (typically, a more complex one) is performing. For example, a logistic regression model might serve as a good baseline for a deep model. For a particular problem, the baseline helps model developers quantify the minimal expected performance that a new model must achieve for the new model to be useful.
