Isn't NFL utter crap?
When you average an learning algorithms performance over a whole bunch of domains that _NATURE WILL NEVER GENERATE_, all algorithms are equally bad.
Paying attention to the theorem is mostly defeatist and counter-productive.
Imagine some ads serving company improves their learning algorithms 10% and is making 100s of millions more dollars. Are you going to say, well, there are billions of other possible universes in which they'd be losing money, they just got lucky that we don't live in those universes?
