Overview of Automated Machine Learning (AutoML): Goals and Components
Automated Machine Learning (AutoML) aims to democratize machine learning by automating the time-consuming and iterative tasks involved in building ML models. This allows data scientists and even domain experts with limited ML expertise to develop high-performing models more efficiently.
The Core Goals of AutoML
The primary goals of AutoML are to:
Key Components of an AutoML System
An AutoML system typically comprises several interconnected components, each addressing a specific stage of the ML pipeline.
The AutoML pipeline can be visualized as a cyclical process. It begins with data preparation, followed by model selection and hyperparameter optimization. The performance of candidate models is then evaluated. Based on these evaluations, the system iterates, refining the model architecture, hyperparameters, or even feature engineering steps until an optimal solution is found or a predefined stopping criterion is met. This iterative refinement is key to achieving high performance.
