what is automated machine learning

These days, almost all companies claim to be doing data science in some form or another. The adoption of automated machine learning (AutoML) technologies in various industries has ushered in a data science revolution. Initially met with curiosity and skepticism, AutoML has rapidly evolved from a niche research field into a mainstream business tool. 

This article explores what is AutoML as a technology, how the industry has approached automated ML solutions, and how it continues reshaping modern businesses’ landscape.

What is Automated Machine Learning? Key Frameworks and Capabilities

In essence, what is AutoML can be summarized as a suite of tools and techniques designed to simplify and democratize machine learning. The technology enables greater access to AI development for those who do not have the theoretical background currently required for a role in data science.

While regular ML involves people manually designing and fine-tuning models to solve problems, machine-learning automation does much of that work for you. It’s like having a tool that helps you pick the suitable model and settings, making it easier and faster to use machine learning for tasks like predictions or recommendations, even if you’re not an expert in machine learning.

AutoML is suitable for companies that have generally already created the prerequisites for ML, such as data capture and data management systems, and want to use ML methods efficiently in various application areas, such as:

  • Anomaly detection

AutoML frameworks can automatically build models that detect unusual network activities indicative of cyberattacks. The system can analyze network traffic data and identify anomalies, such as unusual patterns of data transfer, to trigger alerts for further investigation.

  • Defect detection

AutoML can automate identifying defects in manufactured products. Cameras and sensors can capture images of items on a production line to detect and classify defects like cracks, blemishes, or irregularities, ensuring only high-quality products reach consumers.

  • Quality prediction

In the retail industry, AutoML can predict the quality and demand of various products based on historical sales data, seasonal trends, and external factors. The technology helps retailers optimize inventory levels and improve customer satisfaction by ensuring products are in stock when needed.

  • Predictive maintenance

AutoML can be applied to predict when industrial machines or equipment are likely to fail or require maintenance. Sensors on the devices collect data, and AutoML models analyze this data to detect patterns that indicate potential issues. By addressing problems proactively, companies can reduce downtime and maintenance costs.

Key AutoML components

AutoML comprises several components that automate various stages of the workflow.

  • Data preprocessing. Data preprocessing involves cleaning and preparing raw data for analysis. This includes handling missing values, scaling features, encoding categorical variables, and ensuring data consistency.
  • Feature selection. Feature selection is choosing a dataset’s most relevant and informative features (variables). It helps reduce dimensionality, improve model performance, and speed up training.
  • Model selection. Model selection involves choosing the best ML model or algorithm for a particular problem. It considers data, problem types (classification or regression), and performance requirements.
  • Hyperparameter tuning. Hyperparameter tuning is the optimization of model hyperparameters, settings that are not learned from the data but affect the model’s behavior. Techniques like grid or random search are used to find the best hyperparameters for a given model.
  • AutoML pipeline generation. AutoML pipelines are workflows that encapsulate all the necessary steps, from data preprocessing to model deployment. These frameworks automate the creation of these pipelines, making it easier to reproduce and deploy machine learning solutions.

Streamlining the Data Science Process

How does AutoML work on facilitating the data science process? ML experts manually perform each step in the prototype data science pipeline. In comparison, the introduction of AutoML enables a simpler development process where the necessary code to develop an ML model can be generated with just a few lines. 

Let’s look at the application of AutoML as a solution to a specific problem and examine the output achieved.

AutoML Limitations

Despite being a powerful tool, AutoML also has challenges that organizations should be aware of. These include:

  • Limited customization. AutoML tools may not provide the same level of customization as manually coded machine learning solutions. It can be a limitation when dealing with complex or highly specialized tasks.
  • Data quality dependency. AutoML relies heavily on the quality of the input data. The resulting models may not perform well if the data is noisy, biased, or incomplete. 
  • Over-automation. Automatic feature selection and hyperparameter tuning may not always produce the best results and might require manual intervention.
  • Cost. Implementing AutoML solutions can involve licensing fees for AutoML platforms or cloud computing costs for large-scale training. It’s essential to factor in these costs when considering AutoML.
  • Data privacy and security. Sharing sensitive or proprietary data with external AutoML platforms can raise privacy and security concerns. Organizations must carefully evaluate how data is handled and stored by the chosen AutoML solution.

Bridging the expertise gap between automation and human involvement, considering all known AutoML benefits and drawbacks, is not just a goal. Human-machine collaboration is an opportunity to leverage the strengths of both machines and humans for enhanced decision-making. 

The Role of Data Scientists

Will machine learning engineers be automated? We suppose the question should be: how and to what extent can data scientists effectively use the new Auto ML tools? The general answer is the less use case-specific a task is, the better it can be automated.

Automating certain aspects of ML is not a threat to data engineers but rather a valuable augmentation of their roles. While AutoML can automate routine tasks like model selection and hyperparameter tuning, it cannot replace creativity, domain expertise, and problem-solving skills. 

Instead of job displacement, it is empowering data experts to focus on more complex and strategic ML aspects such as:

  • designing innovative algorithms
  • addressing nuanced problems
  • refining model interpretations

Moreover, data scientists can leverage AutoML tools to concentrate on higher-level responsibilities such as formulating meaningful problem statements, advancing data literacy, and ensuring ethical data practices and fairness in AI.

A strategic approach to working with AutoML

Human oversight in AI is crucial for ethical and accurate machine learning. Here are three strategies for data scientists to achieve this:

1. Check up for diverse and representative data

Ensure that the training data for AutoML models is diverse and representative of the target population. Biases often arise from skewed or incomplete datasets. Carefully curate and preprocess data to increase diversity.

2. Detect bias and use mitigation tools

Implement bias detection and mitigation tools as part of the AutoML pipeline. These tools can help identify bias during model development and provide methods to reduce it, such as re-weighting data or modifying model objectives to prioritize fairness.

3. Conduct regular audits and comply with ethical guidelines

Establish regular audits of AutoML models and adhere to ethical guidelines for AI development. Encourage continuous monitoring of model outputs to identify biases that may emerge in real-world usage. Establish clear procedures to guide model development and decision-making.

Organizations can proactively address biases and errors in AutoML outputs by implementing these strategies, promoting fair and accurate machine learning solutions. Data analytics solution companies can provide critical support in ethical AI usage and help meet the company’s specific needs and goals.
