....if the training data are independently drawn from a xed underlying distribution, then the expected leave out out error equals the expected test error, which measures the generalization ability of the learning method. Leave one out bounds have received much attention recently. For example, see [3, 5, 6, 10] and references therein. Also in [5, 10] the leave one out analysis has already been employed to study the generalization ability of support vector classi cation. In this paper, we extend their results by deriving a general leave one out bound for a class of convex dual kernel learning machines ....
.... For example, techniques related to what we use here have also been applied in [12, 13] In fact, the proof of Lemma 1 is essentially the dual version of the technique which was used in [12] The convergence of the estimated parameter is also related to the algorithmic stability concept in [1, 6]. The former implies the latter but not conversely. Consequently, better bounds can usually be obtained if we can show the convergence of the estimated parameter. Bounds given in [1, 6] are in the style of the convergence of the empirical loss of the estimated parameter to the true loss of the ....

....notion as weak hypothesis stability. Breiman [Bre96b] argues that unstable weak learners bene t from randomization algorithms such as bagging. He nds that, when the weak learner is stable, bagging does not help, and suggests that AdaBoost [FS97] is more e ective in this case. Kearns and Ron [KR99] consider both hypothesis stability and the weaker, related notion of error stability. They prove bounds on the error of leave one out estimates of error rates, but their arguments rely on the traditional notion of VC dimension [VC71] Bousquet and Elissee [BE01, BE02] prove that algorithms which ....
....awkward to analyze within the VC framework. Devroye and Wagner [DW79] were the rst to observe a connection between the stability of an algorithm and its generalization error. Bousquet and Elissee [BE01] proved that uniform hypothesis stability implies low generalization error. Kearns and Ron [KR99] introduced the notion of error stability, and used it to get bounds on the error of leave one out estimates. We discuss several notions of almost everywhere stability, including: strong hypothesis stability , where an algorithm is stable at most training sets, weak hypothesis stability , ....

....This definition of stability is known as uniform stability. It is a restrictive condition, as it needs to hold on all possible training sets, even training sets that can only occurwith probability 0. This motivates the weaker notion of (#,#) stability.

Definition 2.3 (Kutin and Niyogi, 2001) 5] An algorithm A is (#,#) stable with respect to IP S#Z # (A is # stable at S) #. It is obvious that a # stable algorithm is also (#,#) stable for all # 0.

....of the cross validation and holdout estimates in the case where real valued functions are used as classifiers. We then devise and analyse two new error estimates, which we call the adaptive holdout estimate and the adaptive cross validation estimate. The results we obtain are what Kearns and Ron [20] (in the binary valued context) have described as sanity check bounds. This name reflects the fact that the bounds are not better than those one has for the corresponding resubstitution error estimate. Nonetheless, we believe that such sanity check bounds are worthwhile, first, as they show that ....
....no less interesting. Cheng and Titterington [11] have raised the interesting question of what happens to the result stated in Theorem 1 if a cross validation estimate is used in place of a resubstitution estimate. This problem has recently been considered by Holden [15, 16, 17] and Kearns and Ron [20], and a related problem has been studied by Blum et al. 9] There are different types of cross validation estimate. These operate by splitting the sample z into m sections. A section is removed and the remaining examples used in conjunction with L to select a hypothesis h from H. The ....
