The Chinese restaurant table distribution (CRT) is the probability distribution on the number of tables in the Chinese restaurant process. It can be understood as the sum of $${\displaystyle n}$$ independent Bernoulli random variables, each with a different bias: $${\displaystyle {\begin{aligned}L&=\sum … See more

The Chinese Restaurant Process is a metaphorical way for how a Dirichlet process generates data. The Dirichlet process models randomness of a probability mass function (PMF) with unlimited options (e.g. an unlimited amount of dice in a bag). It’s specifically called the Chinese Restaurant Process because the algorithm’s creators, Jim Pitman and Lester Dubins, named it …

by Daniel Dodd. in Easy read. on March 27, 2021. 0. The Chinese restaurant process is a simple yet effective tool. When reduced to its most basic form, the Chinese restaurant process provides us with a distribution over partitions. If we have a set of observations that we want to cluster into groups, the Chinese restaurant process provides an ...

In probability theory, the Chinese restaurant process is a discrete-time stochastic process, analogous to seating customers at tables in a Chinese restaurant. Imagine a Chinese restaurant with an infinite number of circular tables, each with infinite capacity. Customer 1 sits at the first table. The next customer either sits at the same table as customer 1, or the next table.
