Dirichlet distribution

The Dirichlet distribution is a statistical model used to describe probabilities of outcomes that sum to one. Imagine you have a bag containing various colored marbles. If you randomly draw marbles and note their colors, the Dirichlet distribution helps us understand the likelihood of drawing different colors in future attempts based on the proportions observed. It’s particularly useful in fields like genetics, machine learning, and natural language processing, as it allows us to model situations with multiple categories and helps quantify uncertainty about diverse outcomes.
