Title:
The Chinese Restaurant Process

Abstract:
The Chinese Restaurant Process describes a sequence of exchangeable random partitions of the numbers {1,. . . , n}. This process is related to the Ewens sampling model in Genetics and non-parametric Bayesian methods. In this talk, we will see the Process in a regime where the number of parts grows as a sublinear power of n. We will see a non-asymptotic concentration result for the number of parts. The talk is based on a joint work with Roberto Imbuzeiro Oliveira and Rodrigo Ribeiro.
