%description
Find topics in texts which are semantically embedded using techniques like
word2vec or Glove. This topic modelling technique models each word with a
categorical distribution whose natural parameter is the inner product
between a word embedding and an embedding of its assigned topic. The
techniques are explained in detail in the paper 'Topic Modeling in
Embedding Spaces' by Adji B. Dieng, Francisco J. R. Ruiz, David M. Blei
(2019), available at <arXiv:1907.04907>.
