Azure Data Scientist Associate Certification Guide

By: Andreas Botsikas, Michael Hlobil

Overview of this book

The Azure Data Scientist Associate Certification Guide helps you acquire practical knowledge for machine learning experimentation on Azure. It covers everything you need to pass the DP-100 exam and become a certified Azure Data Scientist Associate. Starting with an introduction to data science, you'll learn the terminology that will be used throughout the book and then move on to the Azure Machine Learning (Azure ML) workspace. You'll discover the studio interface and manage various components, such as data stores and compute clusters. Next, the book focuses on no-code and low-code experimentation, and shows you how to use the Automated ML wizard to locate and deploy optimal models for your dataset. You'll also learn how to run end-to-end data science experiments using the designer provided in Azure ML Studio. You'll then explore the Azure ML Software Development Kit (SDK) for Python and advance to creating experiments and publishing models using code. The book also guides you in optimizing your model's hyperparameters using Hyperdrive before demonstrating how to use responsible AI tools to interpret and debug your models. Once you have a trained model, you'll learn to operationalize it for batch or real-time inferences and monitor it in production. By the end of this Azure certification study guide, you'll have gained the knowledge and the practical skills required to pass the DP-100 exam.

Running AutoML experiments with code

So far, in this chapter, you were fine-tuning a LassoLars model, performing a hyperparameter tuning process to identify the best value for the alpha parameter based on the training data. In this section, you will use AutoML in the AzureML SDK to automatically select the best combination of data preprocessing, model, and hyperparameter settings for your training dataset.

To configure an AutoML experiment through the AzureML SDK, you will need to configure an AutoMLConfig object. You will need to define the Task type, the Metric, the Training data, and the Compute budget you want to invest. The output of this process is a list of models from which you can select the best run and the best model associated with that run, as shown in Figure 9.11:

Depending on the type of problem you are trying to model, you must select the task parameter, selecting either classification, regression, or...
