Hi, I put a usage and overview doc for SSVD onto wiki. I'd appreciate if somebody else could look thru it, to scan for completeness and suggestions.
I tried to approach it as a user-facing documentation, i.e. I tried to avoid discussing any implementation specifics . I had several users and Nathan Halko trying it out and actually favorably commenting on its scalability vs. Lanczos but i don't know first hand of any production use (even our own use is fairly limited (in terms of input volume we ever processed) and actually somewhat diverged from this Mahout implementation. Perhaps putting it more in front of users will help to receive more feedback. Thanks. -Dmitriy
