I would like to clarify the meaning of
in question 2 of the final exam, if possible...
Suppose the polynomial model
which is applied to all
X in a data (sub)set
D. There are
data subsets, indexed by
d. Under this model,
is considered to be:
or
where
?
In other words, we average the "functional form" of the function, or we average the parameters of the function over the training subsets?
Thanks in advance.
