AutoML: The Next Wave of Machine Learning

What is Automated machine learning (AutoML) ?

Automated machine learning (AutoML) is the process of automating end-to-end the process of applying machine learning to real-world problems. In a typical machine learning application, practitioners have a dataset consisting of input data points to train on. The raw data itself may not be in a form that all algorithms may be applicable to it out of the box. An expert may have to apply the appropriate data pre-processingfeature engineeringfeature extraction, and feature selection methods that make the dataset amenable for machine learning.

Following those preprocessing steps, practitioners must then perform algorithm selection and hyperparameter optimization to maximize the predictive performance of their final machine learning model. As many of these steps are often beyond the abilities of non-experts, AutoML was proposed as an artificial intelligence-based solution to the ever-growing challenge of applying machine learning. 

Automating the process of applying machine learning end-to-end offers the advantages of producing simpler solutions, faster creation of those solutions, and models that often outperform models that were designed by hand. However, AutoML is not a silver bullet and can introduce additional parameters of its own, called hyperhyperparameters, which may need some expertise to be set themselves. But it does make application of Machine Learning easier for non-experts. Source: Wiki


Various stages of the AutoML process

Automated machine learning can target various stages of the machine learning process:

  • Automated data preparation and ingestion (from raw data and miscellaneous formats)
    • Automated column type detection; e.g., boolean, discrete numerical, continuous numerical, or text
    • Automated column intent detection; e.g., target/label, stratification field, numerical feature, categorical text feature, or free text feature
    • Automated task detection; e.g., binary classificationregression, clustering, or ranking
  • Automated feature engineering
  • Automated model selection
  • Hyperparameter optimization of the learning algorithm and featurization
  • Automated pipeline selection under time, memory, and complexity constraints
  • Automated selection of evaluation metrics / validation procedures
  • Automated problem checking
    • Leakage detection
    • Misconfiguration detection
  • Automated analysis of results obtained
  • User interfaces and visualizations for automated machine learning.Source: Wiki


The Need for AutoML

The interest for AI frameworks has taken off in the course of recent years. This is because of the achievement of ML in a wide scope of utilizations today. Be that as it may, even with this unmistakable sign that AI can give lifts to specific organizations, a great deal of organizations battle to convey ML models.

To begin with, they have to set up a group of seasoned data researchers who direction a top notch compensation. Second, regardless of whether you have an extraordinary team, deciding which model is the best for your concern regularly requires more understanding than information.

The accomplishment of AI in a wide scope of uses has prompted a consistently developing interest for AI frameworks that can be utilized off the rack by non-experts. AutoML will in general mechanize the most extreme number of ventures in a ML pipeline—with a base measure of human exertion and without bargaining the model’s exhibition.



The adavntages of AutoML can be summed up in three noteworthy focuses:

  • Expands productivity by robotizing monotonous assignments. This empowers a data researcher to concentrate more on the issue as opposed to the models.
  • Automating the ML pipeline likewise helps to avoid errors that may sneak in physically.
  • Eventually, AutoML is a stage towards democratizing machine learning by making the intensity of ML available to everyone.
