Imagine you’re sorting through a patient’s medical notes.
You have copies of notes from three previous doctors. All have unique information, but there’s lots of overlap, too.
You want to create a new file, with all the unique pieces of information, but no repeats.
This is where sets come in.
There are three important things you need to know about sets:
1) Every item is unique
2) Items are unordered – there are no indexes or keys
3) We can use “membership tests” to see if a certain piece of data is in a set
That’s all we need to understand for now.
Finally, we can get to what you came for: the fundamentals of machine learning/AI.
