The Lack of A Priori Distinctions Between Learning Algorithms

Plutowski, M., et al. (1994). Cross-validation estimates integrated mean squared error. In Advances in neural information processing systems 6, Cowan et al. some constant set by k and m. It's also true that E(C OTS | φ, d X) is not drastically different if one considers d X 's with a different m'. Accordingly, our summand doesn't vary drastically between d X 's of one m' and d X 's of another. Since n >> m and π(x) is uniform though, almost all of the terms in the sum have m' = m.
