As a result, the basic Latent Dirichlet Allocation (Blei et al., 2003) is still prevalent for practitioners despite various recent advances (Srivastava and Sutton, 2017;Xun et al., 2017;Xu et al., 2018).
due to the efficiency of anchor-based inference, the moment construction often becomes the most expensive step for large corpora, but it is trivially parallelizable as the last averaging step is the only computation that couples individual documents.
