Subject Probability from log likelihood in LDA output
Date Mon, 06 Dec 2010 16:02:23 GMT

As I understand it, the output for LDA is a log likelihood value for
each word/topic pair, which is a function of log(P(w|t)). Is it possible
to invert that function to obtain P(w|t)? I have a feeling it is not,
since it looks like the final value is obtained as a sum of log
probabilities, but I just wanted to check, since an output as a
probability is more readable than the likelihood value given.
