1 Boosting
We have seen so far how to solve classification (and other) problems when we
have a data representation already chosen. We now talk about a procedure,
known as boosting, which was originally discovered by Rob Schapire, and
further developed by Schapire and Yoav Freund, that automatically chooses
feature representations. We take an optimization-based perspective, which
is somewhat different from the original interpretation and justification of
Freund and Schapire, but which lends itself to our approach of (1) choose a
representation, (2) choose a loss, and (3) minimize the loss.
