At eastphoenixau.com, we have collected a variety of information about restaurants, cafes, eateries, catering, etc. On the links below you can find all the data about Dirichlet Chinese Restaurant you are interested in.
The Chinese Restaurant Process, which was introduced by Aldous, is another effective way to represent a Dirichlet Process and it can be directly linked to Blackwell-MacQueen urn scheme. This scheme uses the following analogy: We assume that there is a Chinese restaurant with infinite many tables. See more
