Wrapping my head around Machine Learning and AI, and what I've figured out.

Recently I read an interesting article on Google's Cloud Platform blog about a Japanese cucumber farmer who built a home brew automated system for sorting cucumbers using an Arduino, a Raspberry Pi, and Google's machine learning technology. There's a short video that shows the system in action. The cucumbers are photographed in three different ways using cameras controlled by the Raspberry Pi. The images are sent to the Google Cloud, where they are analyzed for characteristics such as shape, size, and thickness. Based upon the results of the analytics, the cucumber can be classified into one of nine different categories.
