This source directory contains library routines that provide alternative ways of computing generalised second order Stirling numbers used in working with Pitman-Yor and Dirichlet processes (PYP and DP). Included is library routines for posterior sampling on the discount and concentration parameters of the PYP/DP, and some simple demo scripts.

System used for Pitman-Yor processing with topic models, to allow easy scaling to gigabytes of text. Tested on a few versions of Ubuntu Linux and MacOSX and Windows with gcc. In default configuration has no prerequisities. Allows multi-threaded access on Linux version for use in multi-core contexts.

Matching paper with some of the theory at http://arxiv.org/abs/1007.0296, and a series of papers by Buntine and students.
