Hi, All,
I am using the supervised lda function (slda) from 'lda' package in R
for
topic modeling (http://cran.r-project.org/web/packages/lda/index.html), my
data is a collection of documents, and within which each doc has a label.
There are about 97 different categories and 18K documents in total. I tried
to use the slda for training a model from the data (the whole dataset and
sub_dataset), but failed with some strange problems during the procedure:
Iteration 0
Iteration 1
Iteration 2
Iteration 3
Error in structure(.Call("collapsedGibbsSampler", documents,
as.integer(K),
:
Numerical problems (-789.682, 0.0454545).
I am using R 2.15.0 and lda 1.3.1. Any one has any idea? Thanks very much!
