A view of Approximation Theory

IBM Journal of Research and Development, 1987
A selective survey of approximation theory is presented which touches on the concepts of best approximation, good approximation, approximation of classes of functions, approximation of functionals, and optimal estimate. Beginning with the basic ideas of Chebyshev and Weierstrass recent developments and generalizations are given and typical examples are

Flexible Approximators for Approximating Fixpoint Theory

2016
Approximation fixpoint theory AFT is an algebraic framework for the study of fixpoints of operators on bilattices, which has been applied to the study of the semantics for a number of nonmonotonic formalisms. A central notion of AFT is that of stable revision based on an underlying approximating operator called approximator, where the negative ...

Approximation theory of output statistics

IEEE Transactions on Information Theory, 1993
Summary: Given a channel and an input process, the minimum randomness of those input processes whose output statistics approximate the original output statistics with arbitrary accuracy is studied. The notion of resolvability of a channel, defined as the number of random bits required per channel use in order to generate an input that achieves ...

The Theory of the Impulse Approximation

Physical Review, 1952
An integral equation is derived for the scattering of a neutron by a bound proton. This equation has the impulse approximation as the first approximation to its solution. The connection between the impulse approximation and the Fermi approximation is discussed and clarified.

Approximate number sense theory or approximate theory of magnitude?

Behavioral and Brain Sciences, 2017
AbstractLeibovich et al. argue that the evidence in favor of a perceptual mechanism devoted to the extraction of numerosity from visual collections is unsatisfactory and propose to replace it with an unspecific mechanism capturing approximate magnitudes from continuous dimensions.
