Abstract. The purpose of this paper is to define and study a natural rank function\ud which associates to each differentiable function (say on the interval [0, 1]) a\ud countable ordinal number, which measures the complexity of its derivative.\ud Functions with continuous derivatives have the smallest possible rank 1, a\ud function like x^2 sin (x^(-1)) has rank 2, etc., and we show that loss functions in existing methods are consistent, and how to make them consistent if not. 4.1 Statistical consistency We investigate what kinds of surrogate loss functions П†(g(x),y) are statistically consistent with the top-ktrue loss. For this purpose, we study whether the ranking function that minimizes the
