AI will automate a number of repetitive and manual tasks while also assisting and augmenting human decision making. – source: business chief-asia

Since the dimensions could be in thousands, millions, billions or even trillion of parameters we need the machine to help us learn the pattern. Again the basic principle is the same, the machine or computer did not learn by itself, humans give the training inputs to discover the pattern or relationship. The generalized pattern discovered by machine learning can no longer be represented by known mathematical equations that human can see.

Linear regression is a good visualization to explain machine learning. The machine or computer actually did not learn by itself to discover the generalized line equation in slope form. In this example you gave the computer six (6) training data points to approximate the best line equation.

How can you see the mind of a subject matter expert? How can you see if a person is a subject matter expert in artificial intelligence. A subject matter expert usually has very detailed knowledge, can quickly retrieve usable knowledge to solve known problem. A subject matter expert usually can create, design, evaluate, update, maintain, and solve new sets of problem.
