Subject field(s)
  • Compartment - ISO/IEC JTC 1 Information Technology Vocabulary
Universal entry(ies)
34.03.14 (2382)
ISO/IEC standard entry number
DEF

activation function that is centered at a point specified by the connection weight vector and whose position and width are adjusted by learning

OBS

In a radial basis function network, the radial basis functions are the activation functions of the hidden neurons, and constitute a basis set to represent the patterns.

OBS

A radial basis function has a maximum or a minimum, in contrast with the usual activation functions that are monotonic. The most used radial basis function is the Gaussian function.

OBS

radial basis function; RBF: term, abbreviation and definition standardized by ISO/IEC [ISO/IEC 2382-34:1999].

DEF

fonction d'activation qui est centrée en un point déterminé par le vecteur des poids synaptiques et dont la position et la largeur sont ajustées par apprentissage

OBS

Dans un réseau à fonctions de base radiale, les fonctions de base radiales sont les fonctions d'activation des neurones cachés et constituent une base pour représenter les formes.

OBS

Une fonction de base radiale a un maximum ou un minimum, contrairement aux fonctions d'activation usuelles qui sont monotones. La fonction de base radiale la plus employée est la fonction gaussienne.

OBS

fonction de base radiale : terme et définition normalisés par l'ISO/CEI [ISO/IEC 2382-34:1999].

In practice, DLA clusters are grown from the centre of a cell and one record the number of sites in the cluster when its radius of gyration becomes equal to the cell size. Then the number of such occurrences is determined as a function of the number of sites in the cluster at that time. The data are fitted to a Gaussian, and the resulting curve is integrated to obtain Monte Carlo estimates of the coefficients in the renormalization transformation.

The next step toward realism and applicability is taken when the extended Weierstrass function is randomized. The simplest and most intrinsic method consists in multiplying its Fourier coefficients by independent complex Gaussian factors of zero mean and unit variance. The real and imaginary parts of the result deserve to be called Weierstrass(modified)-Gauss functions. In several ways, they are approximate fractional Brown functions.

Subject field(s)

CONT

Noise should be confronted by filtering with a point-spread function that attenuates high frequencies. The two-dimensional Gaussian function is a particularly good choice. The choice reduction of the Gaussian filtering cancels the noise enhancement of the differencing procedures.
