Automated machine learning

Definition

Automated machine learning (AutoML) refers to the process of automating the end-to-end process of applying machine learning to real-world problems. This technology allows users, even those without extensive data science backgrounds, to build and deploy models efficiently. By automating repetitive tasks such as feature selection, model selection, and hyperparameter tuning, AutoML significantly reduces the time and effort required to create accurate predictive models.
