What is the bloody difference here? None worth arguing about that I can
see.
Let me rephrase for you: Your system produces a list of outcomes
ordered by their computed probability. This is your first-order
prediction. If you pop the first element off the list, you can build
another list, a second-order prediction based on the first-order
prediction. Oops, I mean "projection". Get as fancy as you want with
your probability lists, it is a distinction without a difference.
In short, the difference is a few lines of code in implementation. And
that is a difference not worth discussing here as far as I can tell.
