Makoto Yui commented on HIVEMALL-201:
-------------------------------------
In my experience, Instancce-wise normalization has no meaning and has bad
effects.
Libffm is doing Element-wise normalization.
> Evaluate, fix and document FFM so Hivemall produces comparable accuracy to
> LIBFFM

> We expect Hivemall's FFM capability to replicate the similar accuracy with
> LIBFFM's one. Fix its implementation if needed, and document the usage and
> results as well.
