I have some C + python code for stacking autoencoders which share
similar features as DBN (stacked RBM) here:

This is still pretty much work in progress, I will let you know when I
have easy to run sample demos.

However, this algo is not trivially mapreducable but I plan to
investigate on that matters in the coming weeks. Would be nice to have
a pure JVM version too. I am also planning to play with clojure +
incanter (with the parallelcolt library as a backend for linear
algebra) to make it easier to work with Hadoop.
