plda - A parallel C++ implementation of fast Gibbs sampling of Latent Dirichlet Allocation - Google Project Hosting

plda is a parallel C++ implementation of Latent Dirichlet Allocation (LDA) (1,2). We are expecting to present a highly optimized parallel implemention of the Gibbs sampling algorithm for the training/inference of LDA (3). The carefully designed architecture is expected to support extensions of this algorithm.

We will release an enhanced parallel implementation of LDA, named as PLDA+ (2), which can improve scalability of LDA by significantly reducing the unparallelizable communication bottleneck and achieve good load balancing.
