What is AutoML

The term AutoML (Automated Machine Learning) refers to the process of automated development and tuning of machine learning models. It involves a number of operations, including data preprocessing, feature engineering, model selection, and parameter tuning. Automation technologies simplify and speed up this procedure, as well as increase the accuracy of its results, compared to creating algorithms manually.

Specialized AutoML platforms make the creation and deployment of ML models accessible to non-specialists thanks to their clear and user-friendly interface. With their help, teams and companies can spend less time and other resources on machine learning processes by reducing manual labor and streamlining routine, repetitive tasks.

The following AutoML tools will be in the greatest demand in 2024:

Google AutoML. A set of tools and services for developing ML models as part of the Google Cloud Platform. Suitable for businesses and individual users. Includes AutoML Vision for training image recognition algorithms, AutoML Natural Language (natural language processing), AutoML Tables (structured data processing), etc.
AutoKeras. An open-source Python library for automated machine learning. Based on the well-known deep learning library, Keras. Automatically searches for the best neural network architecture for a given data set and task, which simplifies the development of an ML model.
Auto-Sklearn. Another open-source Python library based on the popular ML library Scikit-learn. It uses Bayesian search to automatically train and select the best model variants, as well as hyperparameter tuning to improve performance.
Amazon Lex. A module within Amazon Web Services, it provides tools for automated development of NLP interfaces for services and applications. It allows users to create chatbots and other dialog interfaces.
H2O AutoML. The platform provided by H2O.ai allows you to train ML models for a wide range of tasks, including regression, classification, and clustering. In addition, it automatically finds the best combination of hyperparameters, as well as stores, manages, and deploys finished models.

How AutoML Works

In this section, we will talk about the key principles of the best AutoML tools. Platforms of this type optimize the stages of ML algorithm development: from the initial processing of datasets to the deployment of the finished model. This significantly reduces the time to obtain the result compared to the traditional method, in which each stage is performed manually. They create multiple pipelines that automatically test different algorithms and parameters with specified functions.

A typical automated model training process using AutoML tools includes the following steps:

The user uploads input data based on which the ML model will be trained. As a rule, they are a set of prepared and cleaned big data.
AutoML software pre-processes data through normalization and feature engineering. This improves the accuracy of the models created.
Based on the prepared data, the platform trains several versions of ML models using different algorithms and hyperparameters. This allows selecting the most optimal option.
It then automatically evaluates the performance and accuracy of the results by comparing the trained models with each other and selecting the best one. The selected option is used as the output data system.
The final version of the ML model is deployed by the user and begins to perform the tasks intended for it.

Benefits of AutoML

Automated Machine Learning has a wide range of advantages, including:

Efficiency. AutoML platforms significantly reduce the time and other resources required to train and deploy ML models. They can effectively automate data preprocessing, feature engineering, model evaluation and selection, and hyperparameter tuning.
Savings. Automation of machine learning provides significant cost savings. The use of AutoML systems allows businesses to optimize expenses on hiring specialists and purchasing equipment to perform these processes manually.
Performance. The tools have proven themselves in terms of improving the performance of ML models. By automating repetitive tasks, developers can more quickly and accurately determine the most suitable algorithms to solve a specific problem.
Scalability. AutoML platforms demonstrate decent results when scaling machine learning processes. They efficiently process large datasets and train ML models on their basis in distributed computing systems.
Accessibility. The clear and user-friendly interface of these systems with a low entry threshold makes the processes of developing and implementing ML models more accessible to users without a technical background. Thanks to them, developers do not need to apply deep knowledge of algorithms and machine learning methods.
Human-in-the-loop. Another important advantage of the method is the ability to use it in human-in-the-loop mode — training the model based on user feedback. This helps to better control the process and fine-tune the parameters.
