Technological Background
摘要
We begin this chapter by discussing the fundamentals of information security, which will be useful to understand the rest of the book. After that, we broadly discuss Machine Learning and then we delve into Deep Neural Networks. From there, we build a bottom-up approach, until we reach Voice-Controllable Devices, which are one of the core topics of this book. After analysing how these devices work, we assess what kind of devices are available in the market and how they differ from one another.
