What is AI?
The definition is never definite. From the name, it is->Human-made Intelligence. Then question arises; what is Intelligence? I am going to answer this at the end.
There are four ways to arrive at the output of an AI based agent,
1. Think Like people
2. Act Like People
3. Think Rationally
4. Act Rationally
In the edX course, our objective is to learn the last method.
Rational means achieving your pre-defined goals to fullest by maximizing expected utility. Rationality is the outcome not the thought behind it.
Act Rationally [That I am gonna read in the course]
MAXIMIZE EXPECTED UTILITY
