Which implementation of Parallel LDA is applied in the Topic Extractor node?

For the node Topic Extractor (Parallel LDA) I am wondering which of the two papers is now implemented?

Newman09 or Yao09? Both papers are mentioned in the description of the node and both use some Bayesian classifier to learn the topics in contrast to traditional LDA.

Hi @b0raas,

we are using the MALLET library for the Parallel LDA.
The code says that the implementation is following Newman but a particular data structure developed by Yao is being used as well.

Best regards,
Julian

Thank you very much for the clarification.
It would be great if you could update the description, because the description in MALLET does not say anything about the paper.
