    • Scalable Collapsed Inference for High-Dimensional Topic Models 

      Islam, Rashidul; Foulds, James (Association for Computational Linguistics, 2019-06)
      The bigger the corpus, the more topics it can potentially support. To truly make full use of massive text corpora, a topic model inference algorithm must therefore scale efficiently in 1) documents and 2) topics, while 3) ...
