at 500gb, you can store nearly everything ever written -- let alone compressed.
all statistical learning is a variation on k-nn (see the relevant paper on this) but likewise this is obvious a priori
k-nn is the ideal learner, and a good starting point for analysis
the question for any given system is: what is the learning space, what is the distance function, and how many points are being considered
NNs set up a compressed X,y space, in that space choose points via an empirical expectation, and obtain a weighted average as their prediction
That's just what they do -- there isn't any other mechanism here. The whole formal structure of the NN can be written down on a page of paper
your paper above doesn't deal with this --
it's a reply to the 'forced interpolation' view,
which i haven't espoused. but often NNs are forced interpolated
'extrapolation' is of
course a part of the possible predictive output of a statical learning system -- in that it's latent space is taken to be embedded in R^n
and so one can 'veer off' into R.
Whenever you attribute a higher fidelity space
to a small latent space you are, in effect, extrapolating
