Gaussian distribution

Gaussian distribution

A random distribution of events that is graphed as the famous "bell-shaped curve." It is used to represent a normal or statistically probable outcome and shows most samples falling closer to the mean value. See Gaussian noise and Gaussian blur.

We are looking at the possibility that these distributions for the individual central collisions are Gaussian distributions as suggested by the original hydrodynamic model.
(2) The Gaussian distribution curve can also be applied to the heave deformation caused by tunneling.
In the DPFF, the posterior distribution is approximated by a particle set [mathematical expression not reproducible] which is sampled from Gaussian distribution N(*, [bar.[mu]](k - 1), [bar.P](k - 1)) with same weights [w.sup.i.sub.k-1] = 1/[N.sub.p] .

For an image, the Gaussian distribution describes the distribution of specific pixel brightness that reflects the frequency of some gray numerical value [24].
If [alpha] = 2, X is Gaussian distribution; if [alpha] [member of] (0, 2), X is non-Gaussian fractional lower order distribution.
When L [much greater than] 1, CLT assumption can be invoked and the Gaussian distribution is used to approximate this pdf in [13].
Using the Heavside function [H.sub.[epsilon]], the global Gaussian distribution fitting energy function can be rewritten as follows:

To acquire the sparse solution, make [[omega].sub.j] become the Gaussian distribution with mean value 0, namely:
The distribution of the measuring coefficients of the compressed sensing refers to the histogram 2b.The distribution of the image coefficients after compressed sensing is the Gaussian distribution. Meanwhile, as the characteristic that the vision of human eyes isn't sensitive to the high frequency error but sensitive to the low frequency error, if the design of the quantization matrix also follows the Gaussian distribution, the distribution of the coefficients of the quantization matrix is also the Gaussian distribution.
