I am currently studying Association Rule Pattern Mining. I am reading the explanation on wikipedia about it. Somehow, I feel like I have a problem in understanding the paragraph below.
Can somebody explain this in plain English, I believe the explanation below is written easy enough, but I can't think of "how 1,000,000,000,000" rules are calculated and why we are expected to find rules like "50,000,000,000".
Rule is made of $3$ items, there are $10,000 = 10^4$ items so there are $(10^4)^3 = 10^{12} = 1,000,000,000,000$ rules. Significance is $0.05$ so you get $0.05 \cdot 10^{12} = 50,000,000,000$.
I don't actually know anything about associations, but if I didn't answer your question, you should revise it.
