随机性 Randomness

(重定向自Random)

随机性英语:Randomness)这个词是用来表达目的、动机、规则或一些非科学用法的可预测性的缺失。

一个随机的过程是一个不定因子不断产生的重复过程,但它可能遵循某个概率分布。

术语随机经常用于统计学中,表示一些定义清晰的、彻底的统计学属性,例如缺失偏差或者相关。随机与任意不同,因为“一个变量是随机的”表示这个变量遵循概率分布。而任意在另一方面又暗示了变量没有遵循可限定概率分布。

随机在自然科学和哲学上有着重要的地位。

Randomness 随机性

A pseudorandomly generated bitmap.
Ancient fresco of dice players in Pompei.
The ball in a roulette can be used as a source of apparent randomness, because its behavior is very sensitive to the initial conditions.

Randomness is the lack of pattern or predictability in events. A random sequence of events, symbols or steps has no order and does not follow an intelligible pattern or combination. Individual random events are by definition unpredictable, but in many cases the frequency of different outcomes over a large number of events (or "trials") is predictable. For example, when throwing two dice, the outcome of any particular roll is unpredictable, but a sum of 7 will occur twice as often as 4. In this view, randomness is a measure of uncertainty of an outcome, rather than haphazardness, and applies to concepts of chance, probability, and information entropy.
