Is LSI or LSA implemented? #48

Hi,

Currently, I am comparing different topic modeling algorithms using the OCTIS package. For LSI, I noticed that the OCTIS paper states that (Hofmann, 1999) is implemented, while the Github page refers to (Landauer et al. 1998). Could you specify on which work your implementation is based?

Hello, I believe that LSI and LSA are actually synonyms in the context of topic modeling. In OCTIS, we integrated the implementation provided by gensim. They say in the documentation that their decomposition algorithm is based on this work.
