What is a good explanation of Latent Dirichlet Allocation? (Quora)
If you need to explain topic modeling to your boss, department chair or funder, you would be hard pressed to find a better source of inspiration.
The explanation here ranges from technical to layman to actual example (Sarah Palin’s emails so you might better check on the audience’s political persuasion). Actually it would not hurt to have LDA examples on hand that run the gamut of political persuasions. (Or national perspectives if you are in the international market.)
BTW, if you not familiar with Quora, give it a look.
