Hyperparameters of LDA
Can someone please interpret this graph for me? I find out the alpha value for the different number of topics to find the optimal number of topics which would be required to fir the corpus of data I have.What I could make of this graph is that my corpus is stabilizing at 50 topics. 1 value of alpha means 1 topic per document. Do we want to have 1 topic for each document for our corpus?
