Review of Probability Theory - Stanford University

When a random variable Xtakes on a finite set of possible values (i.e., Xis a discrete random variable), a simpler way to represent the probability measure associated with a random variable is to directly specify the probability of each value that the random variable can assume. In particular, a probability mass function (PMF) is a function p X:

In general, if Xand Yare two random variables, the probability distribution that de nes their si-multaneous behavior is called a joint probability distribution. Shown here as a table for two discrete random variables, which gives P(X= x;Y = y). x 1 2 3 1 0 1/6 1/6 y 2 1/6 0 1/6 3 1/6 1/6 0 Shown here as a graphic for two continuous ran-

RANDOM VARIABLES AND PROBABILITY DISTRIBUTIONS

RANDOM VARIABLES AND PROBABILITY DISTRIBUTIONS 1. DISCRETE RANDOM VARIABLES 1.1. Definition of a Discrete Random Variable. A random variable X is said to be discrete if it can assume only a finite or countable infinite number of distinct values. A discrete random variable can be defined on both a countable or uncountable sample space. 1.2.

Neural Discrete Representation Learning

Lastly, once a good discrete latent structure of a modality is discovered by the VQ-VAE, we train a powerful prior over these discrete random variables, yielding interesting samples and useful applications. For instance, when trained on speech we discover the latent structure of language

Discrete uniform distribution (from X - William & Mary

The shorthand X ∼ discrete uniform(a,b)is used to indicate that the random variable X has the discrete uniform distribution with integer parameters a and b, where a <b. A discrete uniform random variable X with parameters a and b has probability mass function f(x)= 1 b−a+1
