Thanks for putting this video up Derek. It answered everything I wanted to know and gave me great real world examples. I'm pumped to check out the rest of the series.
+Rakesh Sancheti Thank you for taking the time to watch the lecture and for the kind words. I appreciate this very much. Good luck and hope that you enjoy the other lectures too.
It looks like the formula for Confidence and lift is wrong and so are the calculations (10:16). Please check I think it should be more like support(X ∩ Y)/ Support (X)
The formula is correct. X and Y don't have anything in common. (X can be {Milk, Butter} and Y can be {Cereal}). Here, we try to find the probability of X and Y occurring, when only X occurs. ( X -> Y).
