Understanding AutoML

Definition and Concept

AutoML, or Automated Machine Learning, is a process that automates the end-to-end development and deployment of machine learning models. This includes data preprocessing, feature engineering, algorithm selection, hyperparameter tuning, model training, evaluation, and deployment. By automating these tasks, AutoML enables users with limited expertise in machine learning to build and deploy models efficiently while also improving the performance and reliability of models developed by experienced data scientists.

Evolution of AutoML

The concept of AutoML was first proposed in 2013 by researchers at Google Brain, who recognised the need to simplify the machine learning process and reduce the time and effort spent on model development. Since then, several organisations and researchers have developed various tools, platforms, and frameworks to support AutoML.

The evolution of AutoML has been driven by the increasing complexity of machine learning models and the exponential growth in the volume of data being generated. As organisations adopt AI and data-driven decision-making, the demand for skilled data scientists has outpaced the supply, leading to a growing interest in automated solutions like AutoML.
