Notation Mismatch : Documentation LDA and HDP

[budhiraja]

Hi,
I have come across an instance where the notations in examples and APIs is different. In LDA and HDP the show_topics function takes arguments - num_topics=20 and num_words=20 where as in the following places, it is mistakenly reported as something else.

1. http://christop.club/2014/05/06/using-gensim-for-lda/ : model.show_topics(topics=5, topn=5)
2. https://radimrehurek.com/gensim/models/hdpmodel.html : hdp.print_topics(show_topics=20, num_words=10

It will be good to rectify these.

Thanks,
Amar

@dsquareindia , @tmylk , HDP is coming up often with regard to this... needs some cleaning up.

Hi @bhargavvader is there an HDP tutorial somewhere? If I am right HDP build a topic hierarchy, is there a way to look at it? Even in a crude way - say parent-child relationship?

Thanks,
Amar

As far as I know, there is no tutorial nor is there a way to look at the topic hierarchy - though I have not used it extensively, and am unaware if it might exist. I'm going to raise an appropriate issue so someone can tackle it, but will wait for @tmylk or @dsquareindia to confirm if we have more HDP examples.

@markroxor should this be updated post #946 merge?

[markroxor]

Not sure what you mean, do you want me to work on #945 ?

[markroxor]

HDPModel now includes print_topics so 'hdp.print_topics(num_topics=20, num_words=10)' can now be executed but the tutorial for hdpmodel here should be updated as it states show_topics as an input parameter instead of num_topics.

I think this issue can be closed and we can move our discussion to #945 which is a superset of this issue.

Can this be closed now that the base class is made?
