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.

Introduction to NLP

NLP is an area of artificial intelligence (AI) that deals with spoken and written language meaning. This utilizes a machine’s ability to analyze, understand, infer, and manipulate interactions that are human-like with their language response. With NLP, algorithms and computing models are built and deployed that enable computers to understand, interpret, and create human language according to a certain meaning.

The discipline of AI is nothing new and is based on computer sciences from many previous decades ago. The history and lineage of machine learning (ML) are rooted within the mathematics, statistics, and logic disciplines.

Back in time, and only until recently, we used the term cognitive in our language in expressing AI topics; this was to reflect the close relationship between human beings’ cognitive abilities and the machines’ goals of emulating these. AI could be seen by some to be a reference to a “marketing” or ...
