By: Aaron Guilmette, Steve Miles

Overview of this book

The AI-900 exam helps you take your first step into an AI-shaped future. Regardless of your technical background, this book will help you test your understanding of the key AI-related topics and tools used to develop AI solutions in Azure cloud. This exam guide focuses on AI workloads, including natural language processing (NLP) and large language models (LLMs). You’ll explore Microsoft’s responsible AI principles like safety and accountability. Then, you’ll cover the basics of machine learning (ML), including classification and deep learning, and learn how to use training and validation datasets with Azure ML. Using Azure AI Vision, face detection, and Video Indexer services, you’ll get up to speed with computer vision-related topics like image classification, object detection, and facial detection. Later chapters cover NLP features such as key phrase extraction, sentiment analysis, and speech processing using Azure AI Language, speech, and translator services. The book also guides you through identifying GenAI models and leveraging Azure OpenAI Service for content generation. At the end of each chapter, you’ll find chapter review questions with answers, provided as an online resource. By the end of this exam guide, you’ll be able to work with AI solutions in Azure and pass the AI-900 exam using the online exam prep resources.

Technical requirements

To get started with the Azure AI services mentioned in this chapter, you will need an Azure subscription with sufficient access to create and delete resources in the subscription. You can create a free Azure account for evaluation by going to https://azure.microsoft.com/free/.

This free Azure account provides the following:

  • $200 credit to explore Azure for 30 days
  • 12 months of free popular services
  • 55+ other services that are always free

Once you have an Azure subscription in place, you need the Owner or Contributor role at the resource group or resource level.

To evaluate computer vision, you can create a “single service resource” or a “multi-service resource;” they can be explained as follows:

  • Azure AI Language: This is an example of a specific single service resource. This resource can be used with the “free tier” of the Azure AI services you may wish to evaluate; it uses an endpoint...
