I came across this line in the Gensim Documentation- Gensim LDA - "The model can also be updated with new documents for online training."
So my assumption on what it means is - 'Once we have a model trained on one corpus, we can add new data and continue to train the model with new data thereby adding more vocabulary and enriching results. Is this correct?
Is this the same approach discussed in the paper - Online Learning for LDA ? Help me understand this technique.
