Chapters 11-15 discuss the implementation of Intelligent Systems. This part covers all the important components that need to be built, along with their responsibilities, the options, and trade-offs. These are the systems that take intelligence (the models produced by machine learning) and turn it into a fully functional system—executing the intelligence, moving it where it needs to be, combining it, monitoring it, and supporting its creation. These systems enable the operation of Intelligent Systems throughout their life cycle, with confidence.
