Application Regression Learner
R2026aEntraîner, valider et optimiser des modèles de régression de manière interactive
Choisissez parmi différents algorithmes pour entraîner et valider des modèles de régression. Après avoir entraîné plusieurs modèles, comparez les erreurs de validation côte à côte, puis choisissez le meilleur modèle. Pour savoir quel algorithme choisir, consultez Train Regression Models in Regression Learner App.
Ce diagramme de flux présente un workflow courant permettant d’entraîner des modèles de régression dans l’application Regression Learner.
Si vous souhaitez exécuter des expériences avec l’un des modèles que vous avez entraînés dans Regression Learner, vous pouvez exporter celui-ci vers l’application Experiment Manager. Pour plus d’informations, consultez Export Model from Regression Learner to Experiment Manager.
Pour découvrir comment entraîner et valider des modèles de classification, consultez Classification Learner.
