Top AutoML Python Libraries

In the ever-evolving domain of machine learning (ML), AutoML (Automated Machine Learning) has emerged as a powerful tool for streamlining the development process. By automating various stages, AutoML libraries in Python help data scientists and ML engineers build models more effectively, save time, and make ML Accessible to users with less expertise.

In this article, we will look into the Top AutoML Python Libraries.

What is AutoML?

AutoML, short for Automated Machine Learning, refers to automating various steps involved in machine learning, including data preprocessing, feature engineering, model selection, hyperparameter tuning, and even model deployment. The primary objective of AutoML is to simplify the machine learning workflow, making it more accessible to the users. By automating these processes, AutoML reduces manual interventions and various time-consuming processes, which opens up machine learning to non-experts with little expertise in programming language, data science and machine learning.
