The Google engineer who supposedly worked on the "Panda" update is said to be an expert in "decision tree processing."
I've been trying and trying to figure out what that is, looking here:
And other places written purely in technospeak.
What I haven't been able to get a grasp on is what decisions are actually the decisions in question.
Are they the decisions the algorithm makes in interpreting the data?
Are they the decisions of the user, which are better understood by the algorithm?
Can anyone (Tedster?) explain?
