ACM, 36 (4) (1989), pp. 929–965 [10] N. Pollard Convergence of Stochastic Processes Springer (1984) [14] J. Notice that the assumption of an additive noise independent of $x$ is common in statistical literature and is not overly restrictive. Your cache administrator is webmaster.

Inform. Res., 2 (2002), pp. 527–550 open in overlay Copyright © 2006 Elsevier Inc. The performance of a machine learning algorithm is measured by plots of the generalization error values through the learning process and are called learning curve. Learn.

It is impossible to minimize both simultaneously.

Gradient descent is applied to the new training set. It is a foundational element of logic and human reasoning. Generalizations posit the existence of a domain or set of elements, as well as one or more common characteristics shared by those elements. Learning theory: stability is sufficient for generalization and necessary and sufficient for consistency of empirical risk minimization.

Lugosi (1996). As the goal of a learning machine is to minimize the entire quantity $G_ N$, this decomposition could appear as a useless theoretical exercise. Numbers correspond to the affiliation list which can be exposed by using the show more link. Mukherjee, P.
