Hi Everyone,
I am implementing a special case of Random forests. At one point, I
have a list of which I then sample for replacement. So if the list
is 100 elements, I get 100 elements some of them duplicates. How can
I easily get the elements that were not included in the list? I
realize i can do this with a for loop by going through each element
and checking if it's in the list but I am wondering if there is a
faster way.
