I'm trying to run the cvb lda algorithm like so:
$MAHOUT_HOME/mahout cvb -i ./mahout_data/vectors/vectors/vectors\ for\ cvb/
-ow -x 20 -o ./mahout_data/clusters/ -k 140 -dt dist.txt -dict
./mahout_data/vectors/vectors/dictionary.file-0 -a 3
but I get this error
12/07/12 16:06:06 INFO cvb.CVB0Driver: Will run Collapsed Variational Bayes
(0th-derivative approximation) learning for LDA on
mahout_data/vectors/vectors/vectors for cvb (numTerms: 20165), finding
140-topics, with document/topic prior 3.0, topic/term prior 1.0E-4. Maximum
iterations to run will be 20, unless the change in perplexity is less than
0.0. Topic model output (p(term|topic) for each topic) will be stored
mahout_data/clusters. Random initialization seed is 9411, holding out 0.0

Can anyone help me understand what I'm missing?
Thanks,
