Sean Owen commented on MAHOUT-320:
----------------------------------
On a related note, as Robin mentioned, this class could be merged with Bigram,
or vice versa. I don't think ankur would be too bothered (?) about replacing
Bigram, but, it actually seems to be more well developed. It does binary
comparison too for instance. Might this patch take the extra step of merging
the two?
> Modify IntPairWritable in LDA implementation to be binary comparable to
> improve performance.
