Meaning
English Wikipedia has an article on:probability distributionWikipedia
probability distribution (plural probability distributions)
(statistics) A distribution of all possible values of a random variable together with an indication of their probabilities.
Examples
A confidence analysis made this way is statistically valid as long as the output probability distribution stays the same and the network is not modified.
A likelihood function arises from a conditional probability distribution considered as a function of its distributional parameterization argument, conditioned on the data argument.
Another interpretation of the KL divergence is the "unnecessary surprise" introduced by a prior from the truth: suppose a number X is about to be drawn randomly from a discrete set with probability distribution p(x).
Another convention reserves the term continuous probability distribution for absolutely continuous distributions.
A particle speed probability distribution indicates which speeds are more likely: a particle will have a speed selected randomly from the distribution, and is more likely to be within one range of speeds than another.
Arithmetic coding applies especially well to adaptive data compression tasks where the statistics vary and are context-dependent, as it can be easily coupled with an adaptive model of the probability distribution of the input data.
