    Release Notes: Some linkages to the ALVIS system at http://www.alvis.info allow the software to be used to create topic models and annotate linguistically tagged content. Some cleanups with the linkBags Perl utilities have been moved out to CPAN. To see some of the models in action, visit the search demos at www.alvis.info.

      Release Notes: A bug in mpbags that made it constantly use the CPU was fixed. There is no need to update from 1.54 if you don't use mpbags.

        Release Notes: This release focuses on integration with the tool-suite at www.alvis.info. Some useful new scripts include the linkBags, linkTables, and linkMpca set for running MPCA on Web link data augmented with names and title text.

                Release Notes: Changes were made to the way the dimensions are handled, so the .srcpar format for "dimensions=" is now different. MPI now runs, but has yet to be tested or tuned on anything big. Gamma-Poisson models were now okay but are not documented. Partitioning of Omega matrix was broken again. Threading was fixed.

                  Release Notes: The software now compiles on Windows and on 64-bit AMD Opteron. MPI runs and gets results, but is still buggy. The standard run-time platform (ydin, mpserve, ugui, etc.) was redesigned, along with improved directory structure and a new control module (mpctl). Rao-Blackwellized Gibbs sampling (the Griffiths-Steyvers method) runs well. Gamma-Poisson models (Canny, SIGIR 2004) run in Gibbs and mean-field, but prior parameters are difficult and not documented. Topic-specific page rank works well, but setup is not documented.

                    Release Notes: Better defaults were set for the priors. A bug in the ydin build script for the 20 newsgroups test was fixed. Some improvements were made to the UGUI search interface. A bunch of changes were made to make a Windows port easier. A Windows version of yap was added.

                      Release Notes: A fix was made to the C++ code of ydin. The log probability calculations for Griffiths and Steyvers method were corrected.
