Is there an implementation of PLSI in Mahout?

I was looking for PLSI in Mahout a few years ago. Besides that there was no out-of-the-box implementation for PLSI, I didn't found anything in Mahout that would help me to implement it by myself.
So has anything changed ever since? An implementation or at least some support in Mahout?

Thanks :-)

Not really. We had an implementation in Pig contributed a long time ago, but nobody really had time to bring it up to snuff.

We do have a very reasonable parallel implementation of LDA, however, which is often considered the next generation algorithm after PLSI.

Thanks. LDA sounds interesting, I'll have a look into it.
