Automated machine learning

Definition

Automated machine learning, often referred to as AutoML, is the process of automating the end-to-end process of applying machine learning to real-world problems. This includes data preprocessing, model selection, hyperparameter tuning, and model evaluation. By automating these tasks, it allows users with limited knowledge in machine learning to build models effectively, enhancing productivity and enabling more individuals to leverage data insights without needing deep technical expertise.
