MPCA is a comprehensive suite of tools for doing discrete principal components analysis on data sets of size 100Mb or more. Scaling is done using sparse vectors, multi-threading, memory mapping, and other POSIX tricks. Reports, file dumping utilities and other utilities are included. The general problem of discrete components analysis is variously called grade of membership, PLSA, non-neg.matrix factorization, multinomial admixtures, LDA, and multinomial PCA. Whats New in This Release: - Some linkages to the ALVIS system 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..
