> It bugged me that you needed to specify the number of words directly to the
> LDADriver
> eg ./bin/mahout lda \
> -i ./examples/bin/work/reuters-out-seqdir-sparse/tf-vectors \
> -o ./examples/bin/work/reuters-lda -k 20 -v 50000 -ow -x 20
> with this patch you can instead provide a dictionary; we just count the terms
> in the dictionary
> eg ./bin/mahout lda \
> -i ./examples/bin/work/reuters-out-seqdir-sparse/tf-vectors \
> -o ./examples/bin/work/reuters-lda \
> -d ./examples/bin/work/reuters-out-seqdir-sparse/dictionary.file-0 \
> -k 20 -ow -x 20
