[Ligncse256] questions regarding LDA

[Andrea Biaggi]

Hey,
Yes, a word can be assigned to only one topic, in the same document.
But for example in our case if food of D1 and D2 have the same topic 
than n_jk = 2 for that particular word and topic.
I have considered a vocabulary of size 3 but I have 4 different topic 
assignment (one for food in D1 and one for food in D2, but they are the 
same word)
That is what I've understood.
Hope this helps (and I hope it is right too :D)
