Overview of this book

Are you fascinated with applications like Alexa and Siri and how they accurately process information within seconds before returning accurate results? Are you looking for a practical guide that will teach you how to build intelligent applications that can revolutionize the world of artificial intelligence? The Applied AI and NLP Workshop will take you on a practical journey where you will learn how to build artificial intelligence (AI) and natural language processing (NLP) applications with Amazon Web services (AWS). Starting with an introduction to AI and machine learning, this book will explain how Amazon S3, or Amazon Simple Storage Service, works. You’ll then integrate AI with AWS to build serverless services and use Amazon’s NLP service Comprehend to perform text analysis on a document. As you advance, the book will help you get to grips with topic modeling to extract and analyze common themes on a set of documents with unknown topics. You’ll also work with Amazon Lex to create and customize a chatbot for task automation and use Amazon Rekognition for detecting objects, scenes, and text in images. By the end of The Applied AI and NLP Workshop, you’ll be equipped with the knowledge and skills needed to build scalable intelligent applications with AWS.

Preface

Rekognition and Deep Learning

Deep learning is a branch of artificial intelligence and a subfield of machine learning. Deep learning works by inferring high-level abstractions from raw data by using a deep neural network graph with many layers of processing.

Deep learning structures such as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs) have been employed in natural language processing, audio recognition, speech recognition, and computer vision to deliver significant results. Neural Machine Translation has replaced all human-curated translation engines, object detection in autonomous cars uses CNN-based architectures extensively, and conversational AI is powering a variety of customer interactions.

The Rekognition service employs deep learning to provide its various features behind the scenes. It uses pre-trained models so that users do not have to train the system. The exact details are proprietary and confidential to Amazon, but we will learn...
