11. A constant level of white noise is expected from the random variation of sampling the object's light. 12. Smart showed by using physical characteristics that the species were separate and not a result of random variation . 13. It may be used by cyclic repetition of random variation and selection ( like the natural evolution ). 14. A stochastic neural network differs from a typical neural network because it introduces random variations into the network. 15. Diseased hearts in danger of failure show random variation but no such long-range correlation of patterns, he says. 16. Additionally, we usually know that our data has random variations caused by random noise, or worse yet coherent noise. 17. Fisher approximated the distribution of this by ignoring the random variation of the relative sizes of the standard deviations, 18. In some cases, the pulsations do not have a defined frequency, causing a random variation , referred to as stochastic. 19. You might assume random variations that follow a normal distribution, but the truth is a Laplace distribution or something else. 20. Sometimes, in a species with a stable karyotype, random variations that modify the normal number of chromosomes may be observed.
