Corrected a few inconsistencies/confusions/inaccuracies:

  • afaik the acronym PLSA is more common that the lower-case variant pLSA -- need to be consistent anyway.
  • Fisher kernels allow PLSA to be used in a discriminative setting, not as a generative model.
  • Whoever wrote the part about "severe overfitting problems" should provide a reference for that.
  • In "Evolutions...", _discriminative_ was obviously wrong -- I think what was meant is _generative_ -- that's one way to present LDA.
  • Added a bullet on the extension to higher-order data

Errr -- whoever added the graph: it's nice and everything but could you try to use the same notation as in the article? Sunny house (talk) 19:44, 11 March 2008 (UTC)Reply

No, in every paper i have read, the latent variable is always denoted as 'z'. So the text should be changed instead.--137.250.39.133 (talk) 09:21, 18 April 2008 (UTC)Reply
