WebThe Dirichlet distribution is a distribution of continuous random variables relevant to the Multinomial distribution. Sampling from a Dirichlet distribution leads to a random vector with length k and each element of this vector is non-negative and summation of elements is 1, meaning that it generates a random probability vector.
