This manuscript presents a comprehensive guide to Automated Machine Learning (AutoML), covering fundamental principles, practical implementations, and future trends. The paper is structured to assist both beginners and experienced practitioners, with detailed discussions on popular AutoML tools such as TPOT, AutoGluon, and Auto-Keras. It also addresses emerging topics like Neural Architecture Search (NAS) and AutoML's applications in deep learning. We believe this work will contribute to ongoing research and development in the field of AI and machine learning.
