Book Description
This book is the first technical overview of autonomous vehicles written for a general computing and engineering audience. The authors share their practical experiences of creating autonomous vehicle systems. These systems are complex, consisting of three major subsystems: (1) algorithms for localization, perception, and planning and control; (2) client systems, such as the robotics operating system and hardware platform; and (3) the cloud platform, which includes data storage, simulation, high-definition (HD) mapping, and deep learning model training. The algorithm subsystem extracts meaningful information from sensor raw data to understand its environment and make decisions about its actions. The client subsystem integrates these algorithms to meet real-time and reliability requirements. The cloud platform provides offline computing and storage capabilities for autonomous vehicles. Using the cloud platform, we are able to test new algorithms and update the HD map—plus, train better recognition, tracking, and decision models. This book consists of nine chapters. Chapter 1 provides an overview of autonomous vehicle systems; Chapter 2 focuses on localization technologies; Chapter 3 discusses traditional techniques used for perception; Chapter 4 discusses deep learning based techniques for perception; Chapter 5 introduces the planning and control sub-system, especially prediction and routing technologies; Chapter 6 focuses on motion planning and feedback control of the planning and control subsystem; Chapter 7 introduces reinforcement learning-based planning and control; Chapter 8 delves into the details of client systems design; and Chapter 9 provides the details of cloud platforms for autonomous driving. This book should be useful to students, researchers, and practitioners alike. Whether you are an undergraduate or a graduate student interested in autonomous driving, you will find herein a comprehensive overview of the whole autonomous vehicle technology stack. If you are an autonomous driving practitioner, the many practical techniques introduced in this book will be of interest to you. Researchers will also find plenty of references for an effective, deeper exploration of the various technologies.

Book Description
To achieve success in today's ever-changing and unpredictable markets, competitive businesses need to rethink and reframe their strategies across the board. Instead of approaching new product development from the inside out, companies have to begin by looking at the process from the outside in, beginning with the customer experience. It's a new way of thinking-and working-that can transform companies struggling to adapt to today's environment into innovative, agile, and commercially successful organizations. Companies must develop a new set of organizational competencies: qualitative customer research to better understand customer behaviors and motivations; an open design process to reframe possibilities and translate new ideas into great customer experiences; and agile technological implementation to quickly prototype ideas, getting them from the whiteboard out into the world where people can respond to them. In Subject to Change: Creating Great Products and Services for an Uncertain World, Adaptive Path, a leading experience strategy and design company, demonstrates how successful businesses can-and should-use customer experiences to inform and shape the product development process, from start to finish.
