[gensim:138] Using seed words

[Hossein Kazemi]

Hi, I have read several papers that actually start estimation with
some set of seed words. Is this also possible in Gensim package for
LDA modeling? if yes, where exactly this should be done? I am still
new to LDA.
Thanks

Hello Hossein,

seeding with existing documents was a part of gensim some versions
back, in the code that was directly ported from LDA-C. It was meant to
improve convergence (although the final, converged result was the
same).

In recent versions, that code was replaced by a more efficient
algorithm which doesn't use seeding anymore. It is an online
algorithm, so you could say it does "seeding" automatically, in a more
principled manner.

HTH,
Radim

Hi ,
Checking to see if the latest version of Gensim LDA supports seeding ?

Thanks
