One could use an intermediary representation of the plate diagram where i,j,k appears near their respective variable and generator like it's done for the sigma notation. — Preceding unsigned comment added by 82.239.61.147 ( talk) 16:35, 10 July 2011 (UTC) reply

The text says "There are two variables not in any plate; α is the parameter of the uniform Dirichlet prior on the per-document topic distributions, and β is the parameter of the uniform Dirichlet prior on the per-topic word distribution." But the Dirichlet priors don't need to be uniform, do they? In theory, their form could be arbitrary. So I find it misleading that they are said to be uniform here.
