Pachinko allocation available? #286

Closed TimoStolz closed 9 years ago

Hello piskvorky,

thank's a lot for this great library. We use it at our university to uncover topics in messages of patients that use our expert-guided self-help treatments for mental health issues.

Is it possible to do a Pachinko allocation model with gensim? That would help a lot, because these models may uncover correlations between topics in addition to the word correlations within topics. Wikipedia gives a very brief introduction (and another here) and points to some literature.

Again, thanks a lot for this truly great tool!

Hello, you're welcome :)

More topic modelling techniques are on the Feature proposals page, including Pachinko Allocation.

Nobody implemented it in gensim them yet, so no, not available at the moment. Contributions welcome.

Thanks a lot. I'm afraid I'm not enough into it.
