Rayleigh entropy
WebJun 15, 2024 · In physics, communication theory, engineering, statistics, and other areas, one of the methods of deriving distributions is the optimization of an appropriate measure … WebJan 9, 2024 · The entropy fluctuations can be viewed as waves that lead to a scattering of light if the Bragg condition is fulfilled. However, entropy fluctuations do not produce a frequency Doppler shift for the scattered light. Therefore, the entropy fluctuation leads to elastic light scattering, which is commonly called Rayleigh-center scattering.

Webon, the generalized Rayleigh distribution with parameters b and l will be indicated as GR (b,l). Shannon entropy is a very important inferential measure to explain the variability or uncertainty of a random variable. The Shannon entropy for a random variable X with pdf f is given by (see [24,25]), H(X) = E f lnf(x)g. (6) WebJun 15, 2024 · Entropy as an Expected Value Shannon entropy S(f) can be looked upon as an expected value of cln f(x). In Mathai’s entropy (4), one can write the numerator as R X f[f(X)] a a h 1gf(X)dX, which is the expected value of [f(X)] a a h 1. Then, (4) is the following expected value: Ma(f) = E[ff(X)g a a h 1 a a]. (5) The quantity in the expected ...
