Welcome back. In the last two weeks you learned what is AI, and how to build an AI project. This week we'll look at the projects we talked about already, and talk about how projects fit in the context of a company. Whether it's a for-profit, non-profit, or even within a government entity. For the sake of concreteness, I'll talk about building AI for companies will equally apply, no matter what type of organization you're in. Now, in case some of what you hear this week sounds like CEO level talk, don't be intimidated. This is actually useful for everyone to know, the ones that hope, your company will help your organization Improve using AI. And it does take maybe two or three years for a company to become good at AI. To embrace not just one AI project but a sequence of valuable AI projects and become much more effective. But what I hope to do this week is help you paint a vision for where an organization can go over a longer period of time like that. But also end the week with very concrete short steps you can take right away. So let's get started. In detail, these are the topics you'll see this week. First is case studies of complex AI products. So rather then a single machine learning or data science module like what you saw last week. This week you'll see you how multiple modules can come together to build a much more complex AI product such as a smart speaker or a self driving car. You also learn what are the major roles in an AI team. So if ever you think your company can build a large AI team with maybe many dozens or maybe even hundreds of people, what are the things these people will do? We'll start to paint a roadmap for what building an AI team might look like. Third you also learn about the AI transformation playbook of how to help your company become good at AI. Where it goes beyond doing one or two valuable projects, but about making a whole company good at AI and hopefully much more effective and valuable as a result. Finally, whereas some of these steps may take a small number of years to complete. We'll wrap this weeks videos with concrete suggestions on how you can take your first step, right away, toward building AI in your company. Beyond these major topics, we'll also have a couple of optional videos at the end, where you see a survey of major AI application areas and techniques. So, after this week's videos, I hope you have a good vision of how you can help your company use AI and also have first steps you can take right away. Lets get started by going on to the next video.
