Description

AutoML is the process of taking training data with a defined target feature and iterating through combinations of algorithms and feature selections to automatically select the best model for your data based on the training scores. In recent years, AutoML has been seen as a fundamental shift in the way in which organizations can approach machine learning, making it more accessible to experts and nonexperts.

The traditional machine learning model development process is highly resource intensive and requires significant domain knowledge and time investment to run and compare the results of dozens of models. AutoML simplifies this process by generating models tuned from the goals and constraints you defined for your experiment, such as the time for the experiment to run or which models to blacklist.

Francesca Lazzeri details how you can use AutoML for your own hyperparameter optimization and algorithm selection scenario. If you saw Francesca at the O’Reilly AI Conference in New York, she’s here to give you the latest updates. But you don’t have to have seen her before to benefit. She provides you with an introduction to AutoML and share a use case of sales forecasting, where you’ll be introduced to the use case, explore the dataset, engineer the feature, and preprocess the data. You’ll also learn the basics of AutoML, including how to generate a forecast machine learning model; perform data preprocessing, algorithm, and hyperparameter selection; explain the model; train multiple models on a remote cluster; review training results and register the best model; and deploy your model as a web service.

Prerequisite knowledge

  • Experience coding in Python
  • A basic understanding of machine learning and deep learning topics and terminology
  • Familiarity with Time Series Forecast (useful but not required)

What you'll learn

  • Understand the key concepts and principles of time series forecast
  • Learn to set up your own environment for performing AutoML, build different machine learning models using AutoML libraries, review training results, register the best model, and deploy and test it

Are there categories of hyperparameters which are more amenable to being optimized by ML automation?
